ASyou read this, many of you will be getting ready for interpack, or already be at interpack. The Packaging Europe team will be at the event in Düsseldorf for the entire week, and we will be scouring the trade show aisles to report on all the new developments and trends, conducting interviews and filming short videos. We also have our own stand at North Entrance 1/.16, so make sure you stop by and say hello.

Submissions to our 2023 Sustainability Awards have just closed and judging is underway. We will be announcing the finalists on May 29th – watch this space! The winners will be revealed at our combined Sustainable Packaging Summit and AIPIA super-event in Amsterdam on November 14th and 15th. We’re looking forward to seeing many of you there.

The effects of climate breakdown and global heating are becoming ever more apparent, and reaching net zero goals is becoming more vital as time progresses. Major beverage brands have set themselves ambitious targets to reach net zero by 2040. In this edition of the magazine, Frances Butler speaks to PepsiCo and Coca-Cola Europacific Partners to find out how the companies are tackling their emissions, what role packaging plays in their net zero strategies, and to learn about the progress being made towards these goals.

Victoria Hattersley takes an in-depth look at advances in digital print, asks the question: ‘Are we there yet?’ when it comes to market saturation, and explores four key drivers in digital printing, speaking with Advisory4Pack’s Patrick Poitevin and Landa Digital Printing.

In the wake of the upcoming proposed revisions to the European Commission’s Packaging and Packaging Waste Directive, reducing empty space in commercial packaging has shifted into focus. To gain a clearer picture of the new legislation's implications for the sector, Emma Liggins speaks with representatives from H.B. Fuller and Mondi Group.

AIPIA’s Andrew Manly makes the case for antimicrobial films and explores how innovative antimicrobial and antibacterial materials can be commercialised in a cost effective, viable way.

Coming back full circle back to the topic of carbon, food waste is a major contributor to carbon emissions, and the SAVE FOOD initiative was set up to combat the global food waste crisis. At interpack, a new pilot project that sets out to produce food packaging from food waste will be presented. I speak with the project's coordinator from Istanbul's Bahcesehir University as well as Messe Düsseldorf's Executive Director to learn more about the project. Staying with interpack, you’ll find a round-up of just some of the new products you will be able to see at the event

That just leaves me to say we hope you enjoy the latest issue of Packaging Europe magazine, and we look forward to seeing many of you at interpack in Düsseldorf! n

OF PACKAGING IN BEVERAGE BRANDS’ NET ZERO STRATEGIES

With the effects of global heating becoming ever more apparent, and the European Union aiming to be climate-neutral by 2050, companies’ net zero strategies are more important than ever. Frances Butler takes a closer look at how beverage brand owners PepsiCo and Coca-Cola Europacific Partners (CCEP) are tackling their emissions, what role packaging plays in their net zero strategies, and the progress being made towards these goals.

A closer look at PepsiCo

In January 2021, PepsiCo pledged to reach net zero emissions by 2040. To find out what progress PepsiCo is making towards its net zero targets, we heard from chief sustainability officer Katharina Stenholm.

“Packaging counts for approximately 20% of our GHG emissions, with PET being the biggest contributor,” said Stenholm, emphasising that circular, non-fossil-based packaging will play a vital role in achieving PepsiCo’s net zero emissions goals.

Stenholm highlighted packaging design as a key element of this, such as the brand’s aims to design 100% of packaging to be recyclable, compostable, biodegradable or reusable by 2025; cut virgin plastic from non-renewable sources per serving across food and beverage portfolios by 50% by 2030; and scale new business models that avoid or minimise single-use packaging materials.

She also mentioned its goal to achieve 50% recycled plastic (rPET) by 2030 across Europe, and consumer trials of 100% recyclable or renewable snack packaging which began in 2022 “in line with our new goal of eliminating virgin fossil-based plastic in crisp and chip bags by 2030”.

Stenholm underlined Pepsi Co’s support for ambitious recycling targets, increased recycled content targets and deployment of Deposit Return Schemes (DRS), saying:

5 Packaging Europe

rPET for its 500ml and 600ml bottles, but the use of 100% rPET bottles was scaled back for some UK brands in July 2022, citing supply issues.

When we asked Stenholm how this issue was overcome, she explained that whilst 11 markets across Europe have 100% rPET Pepsi bottles (excluding cap and label) already, “we are struggling to enough rPET to continue the roll out at this pace.”

One the reasons Stenholm cites for this is less advanced return systems in some European countries. However, she points out that in Slovakia “return rates have reached over 80%” which has increased the rPET supply, and the company is going ahead with DRS in many countries.

Achieving net zero: what are the main packaging challenges for PepsiCo?

Following on from the difficulties with rPET availability, we asked Stenholm for her opinion on the main packaging challenges that need to be tackled to achieve net zero.

She stated that PepsiCo is focusing on business models requiring little or no single-use packaging ahead of various reusable bottle schemes due for rollout this year, with SodaStream “expected to eliminate the need for nearly 200 million virgin plastic bottles globally by 2025”.

Stenholm says that in 2022, PepsiCo Labs (which works with tech start ups to test industry needs and scale ideas) identified 12 start-ups which may unlock potential solutions to help PepsiCo’s sustainability agenda across its supply chain, including “a physical and digital tracking system for sorting and recycling of waste, a

In January 2021, the company stated its plan to reduce Scope 1 and 2 absolute GHG emissions across its value chain by 75% and Scope 3 by 40% by 2030 (against a 2015 baseline). We wanted to know what progress has been made with this so far.

Katharina Stenholm, Chief Sustainability Officer at PepsiCo

Stenholm said that 12 European markets eliminated Scope 2 emissions by transitioning to 100% renewable electricity for their own manufacturing operations, and with the reduction of Scope 1 emissions is being tackled through piloting new technologies like “biomass, biogas, renewable natural gas, electrification, and hydrogen opportunities, as well as investing in capability-building and knowledge-sharing internally to quickly identify and deploy low-carbon solutions.”

She underlined the importance of reducing Scope 3 emissions in the food industry, saying: “our efforts to reduce value chain emissions focus on our three largest emissions drivers: agriculture, packaging, and third-party transportation and distribution. Meeting our net-zero goals requires that we move quickly and significantly on these, in collaboration with our upstream and downstream partners from whom these emissions originate.”

A closer look at Coca-Cola Europacific Partners (CCEP)

Another brand owner aiming for net zero is CCEP, who have set sciencebased targets to reduce absolute emissions by 25% by 2030 against a 2015 baseline and achieve net zero by 2040.

As part of its World Without Waste campaign Coca-Cola is planning to make 100% of packaging recyclable globally by 2025, and use at least 50% recycled material in its packaging and collect and recycle a bottle or can for each one it sells by 2030. It also claims that 90% of its packaging is recyclable globally.

To learn more about the progress the company is making towards these goals, we spoke to Joe Frances, vice president of sustainability at CCEP. He outlined plans to make sure all packaging is recyclable; using as much

In Europe, “around 53% of all the plastic we used at the end of 2021 was recycled PET,” he said, with around 60% in Australia and 40% in New Zealand. Between 75%-80% of packaging in Europe is being collected for recycling, which differs by market, with Great Britain and France being lower and some markets with DRS being much higher.

According to Franses, the company’s science-based targets and climate strategy is value chain based, with estimates of around 20-25% of total value chain emissions being ingredients; 40% being packaging; 10% from all of its operations in commercial sites; 10% for transportation; and about 10-15% for cold drinks equipment.

He noted that markets will make a difference here, too – “in a market where the carbon footprint of the local grid is higher than the proportion of the value chain emissions attributed, our cold drinks equipment will be higher – simply because it’s using higher carbon intensive electricity.”

Reducing emissions across the supply chain for Coca-Cola Europacific Partners

CCEP has its own goal to achieve net zero by 2040, with around 90% of the bottler’s GHG emissions coming from the supply chain. We asked Franses to explain what steps are being taken towards this goal, and how packaging can play a role in achieving it.

Franses stated: “Supplier engagement is a fundamental part of how we will proceed on our journey to net zero. We will not be able to reduce our emissions unless we can reduce our Scope 3 emissions”.

He set out three things CCEP has asked suppliers to do: set their own

Sharing data is a key point for Franses. “If you’ve got a can supplier doing excellent work to reduce the carbon footprint of the can, we need to be as close to their data as possible so we can incorporate that into our carbon footprint numbers.

Most big companies will use average data for the entire sector or for a reason. We want to move to using supplier specific data that will help reflect the carbon reductions our suppliers are engaged with.”

In addition, he mentioned CCEP’s sustainability linked finance chain with Rabobank, which will incentivise and reward suppliers for improving their performance in this area, as well as the Supplier LoCTS programme run by the consultancy Guidehouse (which the bottler and many of its packaging suppliers are involved in) which helps to “upscale and upskill supplier activity on carbon reduction.”

In 2021, 98%.3 percent of CCEP’s primary packaging in Europe was recyclable, and the company aims to ensure that 100% of packaging is recyclable by 2025. Franses said that in Europe, there are still some elements that don’t meet the requirements, such as some of the pouches used for Capri Sun, which are not always easily collected for recycling.

Investing in PET recycling plants has taken place in France, Australia and Indonesia, and there is a single-use plastic directive in Europe that requires 90% collection of plastic bottles by 2029.

There is also Packaging and Packaging Waste regulation which will introduce minimum requirements for DRS and make them mandatory across EU member states. Franses underlined CCEP’s support for this infra structure “as long as it’s well designed because it will help because it will help us to get in excess of 90% of our packaging back.”

In terms of collection, he stated that as a global Coke system, CCEP has a commitment to collect a bottle or can for every one it sells, and while “we can’t possibly collect every single pack we put onto the market, we will be looking at equivalents. That depends upon not just recyclability, but the collection functioning really well across all of those markets.”

Packaging Europe 11
CCEP has asked its suppliers to do three things: set their own sciencebased targets; shift to using renewable energy; and share their data with CCEP, for example, making sure the electricity a PET producer is using to make a can is coming from renewable sources.

HOT TOPICS AT HEUFT

Digital technologies for track & trace. Inline inspection for security in the circular economy. Foreign object detection for product safety. Smart image processing for efficient resource management: HEUFT has the right solutions.

Digital technologies for the bi-unique identification, tracking, serialization and aggregation of the most varied packs will be presented at Stand A43 in Hall 13. From proof of origin to the documentation of the whole packaging process they generate "Big Data" for traceable production.

Right up to the archiving of the detection images this also applies to all the data of network-capable HEUFT systems for the inspection of empties for safely reusable packaging in the circular economy and for the examination of full containers for high product safety.

A highlight is the HEUFT eXaminer II XT. With optimized pulsed X-rays and a revised mechanical design it offers more detection accuracy during the inspection of still unpackaged product mass and more flexibility for space-saving integration.

PFM Packaging Machinery, a leader in the production of automatic and robotic systems for flexible packaging, will be showcasing technological innovations at interpack in hall 13 / A03.

Among the new products on display at the event, visitors will be able to see the D-400 EPT Series Horizontal Stand-up Pouch and the RQ700/800 Series Vertical Stand-Up Pouch.

The D-400 EPT Series is equipped with an electronic pouch transport system with magnetic carriages, adding further benefits to the D-Series:

Innovative image processing combines artificial intelligence with human expertise to clearly distinguish harmless objects from critical ones, so that resources are no longer wasted and only truly unmarketable products and packaging are rejected.

SERIES

The magnetic carriages group the pouches together, thus doubling the filling time compared to traditional systems. The machine can switch from Duplex to Triplex configuration in 20 minutes with increased bag output and width format changeover. and can produce up to 200 stand-up pouches per minute.

The RQ700/800 is the VFFS intermittent motion packaging machine that can produce pillow bags, block bottom packs and doy-style packs, also with zip. The innovation lies in the new sealing unit concept, i.e. the QRM, which can be pulled out with a special carriage and replaced in a few minutes with a second unit to switch from a pillow or block-bottom pack to a doy-style pack. The format changeover takes place without the need for further adjustment, and the sealing control system allows the sealing force applied to each side of the pack to be set, managed, measured and stored independently.

DISCOVER THE POTENTIAL OF ELBA’S COMPACT MACHINE FOR RETORT POUCHES

ELBA S.p.A. has recently launched an innovation around the modular structure of its SA-V pouch making machine.

Despite its compactness, this updated model can preserve high levels of productivity and efficiency for the manufacture of retort pouches with bottom inserted gussets.

Customization is one of the features that distinguish ELBA in the pouch making machines market, indeed the SA-V can be designed for two or four-lane production.

Automation is another essential characteristic of ELBA’s machines: the automated collecting table allows to reduce time and effort as pouches are piled up automatically at the end of the process.

This compact SA-V has been engineered to make machine management easier in every respect, from setup to maintenance, and is equipped with new design components. The latter guarantees maximum reliability, regarding speed and sealing quality, and minimize maintenance downtime, limited only to wear and tear parts.

ATinterpack, the MBP 12C4 will be presented, designed to minimize impact and eliminate the risk of product breakage during weighing phases.

The strength of the 12C4 multi-head weigher’s design concept is to reduce the product's falling height as much as possible and with it the impact against rigid surfaces.

The multi-head weigher is characterized by 12 weighing buckets fed directly from the vibrating channels, excluding the pre-dosing buckets. Furthermore, the central vibrating plate, used for distributing the product on the radial channels, has a flat horizontal shape, which improves the

product's distribution on the channels and minimizes the product's falling height.

The product's impact in the buckets is reduced to a minimum thanks to the degree of inclination of the bucket walls.

The falling height from the pans to the belts is only a few centimeters, as is the distance between the belts and the discharge point.

All maintenance and cleaning operations of the multi-head weigher are made easy: the four main belts rotate 90° downwards, and the carpets are easily removable.

The MBP 12C4 is integrable with an inclined vertical packaging form fill and seal machine,

specific for fragile products, or it can feed an output conveyor belt that, in turn, can feed different types of packaging machines.

PFM DEVELOPS AND APPLIES ROBOTICS TO HIGH-SPEED PRODUCTION LINES

PFM will present a packaging line produced by SPS that features a robotic feeding system with computer vision for product recognition at interpack.

The line can manage the mixed-up bars on the exit belt: the robots recognize them, pick them up and deposit them on the feeding belt of the first high-speed horizontal packaging machine.

The first part of the line wraps the bars in a primary flexible packaging; the packaged product is then rotated before coming out, to feed the second packaging machine; eventually, this will create multipacks of bars thanks to iTRAK, the intelligent feeding system by Rockwell.

The line offers an increase in production rates: the automatic line for bars can reach a speed of

up to 1000 pieces per minute, while ensuring a consistent quality of the final product. Furthermore, it offers reduced downtime. The automatic line for bars is equipped with a system that allows a fast and easy format changeover.

Furthermore, the automatic line for bars features a smaller footprint.

At interpack, visitors will be able to see the whole line running with its predictive maintenance system and augmented reality for technical assistance, which allows monitoring of the machine’s status in real-time and to take prompt action in case of anomalies or faults.

FOCUS ON CIRCULAR PLASTICS

Plastic solution expert Braskem is supporting the transition of the packaging industry towards a carbon neutral circular industry.

Braskem believes the future of both plastic and packaging relies on the development of low carbon, circular solutions together with stakeholders. Over a decade ago, Braskem launched I’m Green™ Polyethylene and EVA, a premium biobased plastic solution. Braskem is supporting the growing demand for more sustainable packaging by expanding production of sustainably sourced bio-based plastics from currently 260kt

to 1Mt in 2030. Each ton of green polyethylene used avoids 5 tons of GHG emissions and is 100% recyclable. This contributes to achieving a carbonneutral circular economy and to decoupling from fossil feedstock. More recently, Braskem launched Wenew, a portfolio of chemically and mechanically recycled resins, to support the transition to a circular plastics chain. Braskem is committed to expanding the recycling portfolio to include 300kt of products by 2025 and 1MMt by 2030.

“At Braskem we are focused on supporting converters and brand-owners to achieve their

sustainability goals in packaging and at this year’s interpack, our goal is to show the various examples of how we can help the packaging industry to achieve those goals.”,

WILL MANDATED SPACE

the Packaging and Packaging Waste Directive. For grouped and transport packaging applications, the amount of empty space in a pack – which includes room left for filling materials – should correspond with the total volume of the product(s) and their sales packaging, and it is up to the economic operators facilitating these kinds of packaging to ensure that the space-to-product ratio should only ever reach a maximum of 40%.

This approach has come under fire by key players in the packaging industry at large, some of whom have argued that an absence of scientific or empirical evidence, combined with a lack of consideration for the range of properties that come with packaged products, has resulted in ‘arbitrary’ restrictions. Even so, consumer demand for less, more spaceefficient packaging remains on the rise.

In search of a clearer picture of the new legislation’s implications for the e-commerce sector, Emma Liggins consulted Nedim Nisic, e-commerce director at Mondi Group, and Tania Montesi, global e-commerce manager at H.B. Fuller, about their respective takes on the situation.

Broadly speaking, what impact could a mandated reduction of space in e-commerce packaging have on the e-commerce sector?

TM: We believe it would have a positive impact on the e-commerce packaging market. According to our consumer surveys, right-size packaging is desired by consumers. Yes, the reduction of space will require packaging designers to adapt their designs to be regulation compliant, but this process will drive the creation of new innovative packaging designs that reduce empty space and design out waste. We believe it is possible to achieve this reduction in space without compromising product protection and stability during transit.

Of course, there are other benefits associated with a reduction of packaging: right-sized packaging should result in a reduction of carbon emissions, as it allows more packages to be loaded onto a delivery vehicle and logistics optimisation across the supply chain. It should also enable energy savings and cost-effective solutions, as less materials will be required to manufacture the package.

27 Packaging Europe

thirds (67%) of respondents said they would avoid shopping with an online retailer that sent orders in oversized packaging, while almost as many (62%) said they would also avoid shopping with a retailer that used excess internal packaging material.

With the growth of online shopping, packaging has become a crucial aspect of the brand experience. To strengthen customer loyalty, brands need to consider consumer packaging demands for sustainable materials, convenient returns and recycling, and right-sized packaging.

What are your thoughts on holding economic operators responsible for enforcing the 40% spaceto-product ratio? Is it a useful or realistic goal?

TM: This gives full clarity on where the accountability sits. The proposed date of 2030 is a target, and we believe that economic operators should start working towards the

innovative package redesign with less ecological impact.

We believe that the 40% target is realistic. That is not to undermine the challenges it presents to e-commerce packaging – the supply chain has many obstacles to overcome in achieving this space reduction target. For example, fragile items, such as glass drinkware, need to be suspended away from the outside of the packaging, with added packaging components to fill the space between to

Certainly, meeting the empty space ratio of 40% will require some innovative design thinking but we believe it is possible. This being said, many e-tailers will look to invest in automated right-sizing equipment to achieve this goal, assuming the volumes and financials justify the investment. This investment will help them achieve the directive’s goal and reduce their packaging and overall freight costs, as calculated by Dimension and Weight Ratio (DIM), through the elimination of protective components or void fillers.

29 Packaging Europe

NN: Mondi is committed to making packaging that is sustainable by design, and for e-commerce minimising the amount of packaging required is a key consideration. We offer a multi-material portfolio, including kraft and functional barrier paper, paper bags, and corrugated solutions. With a broad product portfolio, deep technical expertise, and an integrated value chain, we can help customers to make the best packaging choices. Partnering with customers provides an opportunity to innovate and create fit-for-purpose solutions that contribute to a circular economy.

Would a widespread reduction of space effect costs, within the industry or amongst consumers?

TM: Yes, and we all should see a positive effect on costs. The reduction of space in e-commerce packaging has an overarching goal to reduce packaging waste and the amount of materials used. The reduction of the empty space will decrease or eliminate the need for void fillers, like air cushions, polystyrene, paper fillers, or bubble wrap, which can reduce the overall packaging cost.

Optimised packaging should also provide a reduction in freight costs that have been calculated by the major companies using DIM since 2015. Time will tell if the transportation industry updates the DIM costing approach, as the size and weight of packaging reduce and potentially bring down their revenue stream.

NN: We believe that overpackaging is neither sustainable nor cost-effective. A reduction of space will have an impact on the whole supply chain: less empty space means more cost-effective transport, lower material usage, and lower material cost. Furthermore, better product safety – thanks to a better packaging fit – will minimise product loss, lower stocking costs, and reduce the overall Total Cost of Ownership. Our latest annual e-commerce consumer research also shows that overpackaging can negatively influence buying decisions. Customers prefer not to support retailers that use too much or improperly sized packaging, which could lead to online retailers losing money from potential customers.

Should we be concerned that less space for protective packaging could lead to products being damaged in transit?

TM: No, and it is time to redesign packaging and get creative. Many companies are already embracing the challenge and have launched some excellent innovative solutions. For example, the tableware brand Lenox redesigned the packaging for its red wine glasses, which enhanced sustainability and greater product protection for Amazon’s Frustration-Free Packaging program requirements.

31 Packaging Europe

using the right materials. By ensuring a good fit between the product and its packaging, the product is less likely to move inside the package, providing stability and protection.

Do you feel that the Packaging and Packaging Waste Directive addresses the biggest challenges to sustainability that the e-commerce industry is facing?

NN: We support the European Commission’s ambitions for making packaging part of the solution in a circular economy. Our experience shows that sustainability needs to be considered from a holistic perspective, considering all the potential trade-offs. This means considering the environmental impacts of our products at each stage of the value chain, from sourcing raw materials to product design and end-of-life, to drive progress towards a circular economy and eliminate unsustainable packaging.

TM: Every step forward matters and while PPWD may not solve all of the sustainability challenges faced by the e-commerce indus try, it is a big step in the right direction. The focus to reduce space in e-commerce packaging most likely received extra atten-

tion due to the fast growth experienced over the last couple of years. In 2021, European e-commerce grew by 13% to €718 billion according to industry figures. Even though some innovations have already focused on lightweighting e-commerce packaging, the amount of waste packaging generated has continued to grow significantly. Also, the responsibility for correct end-of-life packaging disposal, i.e., recycling, shifted more to the consumers.

Regulations generate innovation – and as the packaging industry finds the answers, we may well see the introduction of alternative fibres as another advanced step on

the sustainability journey. For example, the Ukrainian green tech company Releaf is using their patented technology to turn leaves collected by city authorities, which would normally be burnt or left to decompose, into cel-

Empty space is a key area of consideration for the industry, as it is a loss for all parties, including customers, online retailers, and suppliers. We expect that the industry will continue working to reduce the amount of unused space in e-commerce packaging with more innovative and functional designs that deliver on sustainability goals and product requirements.

I believe we’ll see multiple strategies that will ensure the e-commerce industry is able to comply with these new regulations. There will be a shift for smaller items to be shipped in flexible, paper-based mailers instead of rigid corrugated boxes to reduce empty space. These mailers are lightweight and cost-effective. We are already seeing many innovative, 100% fibre-based designs entering the market, including paper bubble mailers that are constructed with kraft paper to mimic plastic bubble padding. Others use honeycomb to provide cushioning and protective functionality

We know the packaging industry is both highly innovative and motivated to develop new packaging formats and materials that not only comply with PPWD requirements but also support the circular economy journey. For sure we’ll see new designs that minimise the amount of empty space and packaging required and are easy to recycle at end of life. But we’ll also see new packaging designs that enable different ways of consumer use such

TALKS

SUSTAINABILITY IN ADHESIVE TAPES

In the latest of our Wider View series, we turn our attention to the subject of adhesive tapes. Longstanding industry expert monta discusses how the sector can reduce its environmental impact and increase efficiency and product security along the supply chain.

The importance of adhesive tapes as a key driver of green innovation across the packaging industry should not be overlooked. Packaging tapes are a small yet vital component of the whole packaging concept. The right choice of tapes can save a lot of resources, material and time and also enable packages to be manufactured from more recyclable materials – and this is just the start. They can also increase the pack’s ability to withstand tough conditions during transit, reducing product waste and therefore enhancing resource efficiency. And no damaged goods, of course, also equates to greater customer satisfaction.

monta Klebebandwerk GmbH, the subject of this article, is well aware of the many possibilities for this sector: monta tapes are used for box and bag sealing, carry handles, strapping, surface protection and splicing.

Its product range – which we will discuss in more detail – includes the carbon-neutral Greenline tapes, namely paper-based tapes, biodegradable tapes and tapes that eliminate the need for virgin, fossil based raw material, to name just a few.

monta focuses on natural rubber based adhesives which it develops and manufactures in-house, as opposed to acrylics or hotmelt, which are the other alternatives for this segment. Sylvia Di Felice, Head of Product Management & Marketing, explains why.

“Natural rubber adhesive has the benefit of naturally having a relatively high biobased content of around 50% (whereas acrylic and hotmelt typically are of 100% petrochemical origin). It is suitable for many demanding applications, such as below zero temperatures or high humidity, and

36 Packaging Europe

thanks to its unique flowing properties is great for even adhering to recycled cartons and other difficult surfaces. Another plus is that with natural rubber, one layer of tape is (almost) always sufficient to achieve the desired bond. This means minimal material input is required.”

Why are packaging adhesive tapes so important?

According to monta, the global market for packaging tapes is estimated at 30 billion square metres per annum. The majority of this comprises tapes with a plastic-based backing, with paper backing taking up a smaller – albeit growing – part of the market. The biggest application is carton sealing, in which the tape is applied to close the box. In most cases, says the company, at the end of life, the adhesive tape enters the cardboard recycling stream, where it’s usually separated from the carton and incinerated for energy recovery or heating.

Sustainable innovation in the adhesives sector is today focused on several different areas. For example, on the raw materials side the tapes themselves can be manufactured using ever-more environmentally responsible chemical formulations, while substrates can also be made from more eco-efficient, recyclable or circular materials.

A different, possible future end-of-life solution might be pyrolysis: instead of incinerating it, the tape is converted into liquid oil or gas as a basis for new raw materials, thus closing the loop.

Material reduction is also a big priority, as Sylvia Di Felice explains:

“As a result of choosing a low-quality tape or one that isn’t well suited for the application, we often see that far too much tape is applied to achieve a secure seal. This is neither costeffective nor sustainable, as unnecessary material and time is wasted. Often the user is not aware of the fact that if using the appropriate tape technology for their specific carton quality, a single layer application and short strip of tape is sufficient Put in other words: the less tape you require for the desired result (e.g. closing a shipping carton), the more economical and sustainable your packaging. In addition, a neatly sealed carton, without excessive packaging material, leaves a positive impression on the customer. And with an individual print on the tape, companies can convey their brand message in an easy and sustainable manner, another value-added adhesive tapes offer.”

The big market challenges

But while progress is continuous, the industry also has many ongoing obstacles to overcome. New or revised regulations and initiatives – among them the European Green Deal, the Circular Economy Action Plan, the updated Packaging and Packaging Waste Directive, the Chemicals Strategy for Sustainability, the SUP Directive – all demand greener packaging solutions.

“Sustainability has been an integral pillar of our corporate strategy for many years, enabling monta to anticipate the current trend – which translated into our monta Greenline range to offer products that fulfil sustainable market requirements,” says CEO Daniel Lückfeldt. “The challenge in some cases is the price of new raw materials! Everyone wants to have green packaging, but if the price premium compared to the ‘conventional, fossil based’ tape is perceived as too high, the green intentions often subside. But the price gap is getting smaller, and availability of alternative raw materials is also improving, so we see a positive development.”

Another challenge the company mentions when it comes to using sustainable packing tape alternatives is technical performance: “They must perform equally well [as existing products] if not better. The box must stay closed during transportation to ensure the packaged goods reach their destination safely and intact. Before launching eco-friendly alternatives, extensive research & development work and practical testing is mandatory to achieve the required technical specification.”

Working towards carbon neutrality and biodegradation

One of the primary goals of the European Green Deal is to make Europe climate-neutral by 2050, and the adhesives industry is supporting this in various ways. For its focus on sustainable responsibility, monta has been awarded the silver medal for sustainability by international ratings platform EcoVadis multiple times – most recently in 2022. The company’s Greenline tapes are a key part of its carbon neutral strategy.

“We calculated the product carbon footprint based on the GHG protocol (Greenhouse Gas Protocol Product Life Cycle Accounting and Reporting Standard) for all our Greenline tapes with great results: monta biopack® & monta reTec offer lower carbon footprints than conventional polypropylene tapes. To go one step further, we decided to offset all unavoidable CO2 emissions by investing in certified climate protection projects. Some call this greenwashing; we don’t. monta has established an Environmental ManagementSystem to EN ISO 14001 in 1999 and has been energy certified to EN ISO 50001 since 2015. Part of this certification is setting an annual target to lower our energy consumption. We report regularly and also get audited on our progress annually.” (See Figure 1)

37 Packaging Europe

monta biopack®, incidentally, was a finalist in our 2020 Sustainability Awards. Aside from having a high biobased content (around 90% based on dry weight) the product is also compostable under industrial conditions –certified by TÜV Austria with the OK COMPOST Industrial mark. While, as mentioned above, many self-adhesive packaging tapes have a fossil-based plastic backing and are often coated with an acrylic or hotmelt adhesive, monta biopack® uses a biobased PLA film and a natural rubber adhesive.

It should be pointed out here that while biodegradability has come a long way and shows strong promise, there are still some question-marks surrounding it that the packaging industry as a whole is attempting to address. For example, there is an important difference between home compostability and industrial compostability – something that can still be confusing to consumers, which may be in part a labelling issue.

“It is true that the infrastructure for compostable products is not widely established yet and there is room for improvement,” says Daniel Lückfeldt. “And there are voices that therefore don’t like packaging alternatives made from biobased plastic, like monta biopack®, which is made from PLA film. The perfect ‘green’ packaging solution has not been invented yet but biobased plastics have huge potential to replace fossil based plastics, with lower carbon footprint and potential to be able to move away from dependence on fossil based materials. Depending on the product and application they can also successfully be recycled, e.g. as a mono-material solution where monta biopack® is used for sealing PLA bags. Furthermore, part of

the TÜV OK COMPOST certification also tests on eco-toxicity, which our tape passed, so another benefit there. As to the marketing of compostable packaging materials, clear communication is important, so as not to confuse or even mislead the consumer.”

Replacing plastics with paper?

Across the packaging value chain, products that were traditionally plasticbased are increasingly being replaced with fibre-based solutions. But how does this apply to adhesive tapes, where strength and durability are so vital? Are paper-based tapes always sufficient?

“We offer a paper-based tape that is silicone free and perfect for light to medium heavy boxes. It adds a more natural look and is popular where a mono-material tape solution is desired. It also offers stunning print results,” says Sylvia Di Felice.

“A drawback is that most paper tapes may not be strong enough for heavier cartons or harsher conditions, and the CO2 footprint of paper tapes compared to other conventional tapes (PP) and other sustainable tape options (biobased) unfortunately is much higher. Also, not all paper tapes stay in the cardboard recycling stream and get incinerated instead of recycled at the end of life.”

monta says its “eco-friendly answer for heavier boxes or more demanding applications is using a filmic tape with either a high renewable raw material content (like monta biopack®) or one that significantly reduces the

38 Packaging Europe
Figure 1

need for virgin fossil-based raw materials, like the above-mentioned monta reTec, a tape manufactured with a film backing made from reprocessed polypropylene, which eliminates the need for virgin fossil based raw material by over 99%. For both products CO2 emissions (cradle to gate plus waste) are lower than with other tapes.”

2023 and beyond

Looking ahead at the bigger picture, monta sees strong prospects for ‘greener’ alternatives across the wider adhesive tapes sector. In order to get the most from this, says Daniel Lückfeldt, “Staying flexible, ideally anticipating the direction the market will take and responding quickly to demand are the main ingredients for continued success.”

And monta itself has some exciting products in its R&D pipeline, some of which may be revealed at this year’s interpack in May. To find out more, come and talk to the team at Hall 7, stand 70C20 (where they will be serving some local specialties!).

We have heard a lot in this article about the benefits of working with the right adhesive tape producer.

We were interested to delve a little deeper into this by getting the perspective from monta’s customers themselves. We therefore put some questions to Cameron Bell, General Manager of Australia-based Stylus Tapes International:

PE: Why is the correct choice of adhesives tapes essential to help you meet your sustainability goals and ensure product security?

CB: It is our opinion that for the Australian market it has to be truly sustainable. That means certified compostable or recyclable. If recyclable, the process of material collection and recycling has to be viable and accessible for both domestic and commercial use. If compostable, the process of collection has to be available and composting facilities must be accessible. The tape should also perform according to consumer expectations and be suitable to the packaging application. Another aspect is the continuity of supply of the sustainable material.

PE: What are the biggest challenges you face in this regard?

CB: Consumer and industry awareness of the need for sustainability is a big challenge, as is recycling collection accessibility and viability. There is also the question of whether consumers and the industry will accept the need to pay a premium for sustainability, as prices for sustainable raw materials are higher.

We also spoke with Thilo Simon, Lead Buyer (paper, wood, plastics) at the Industrial and Packaging Division at Germany-based TAKKT Group, about the impact of the e-commerce sector:

PE: Has the recent e-commerce boom increased the importance of efficient and sustainable bonding solutions?

ST: We have been experiencing an increased demand for sustainable products for some time now. The recent e-commerce boom has reinforced once again the importance of efficient and sustainable bonding solutions because packaging is a critical component of the supply chain, and online shopping has significantly increased the volume of packages being shipped. Efficient and sustainable bonding solutions, such as the monta paper packaging tape or monta biopack®, can help reduce waste, improve the packaging process, and create a more sustainable supply chain.

ARE PLASTICS REALLY THE ENEMY?

For this edition of the Wider View, Victoria Hattersley speaks to PakTech about our collective attitude to plastics and how the industry is – or should be – addressing the plastic waste problem.

INthis article, we’re going to talk about plastics. Because while there are many recognized benefits to these materials – they are strong, lightweight, durable, reusable, aseptic, help prevent food waste, etc. – we know that they have also garnered a lot of negative press. And yes, it’s fair to say there is a good reason for this. According to the UN, today we produce around 400 million tonnes of plastic waste each year. (I say ‘we’, but as we know the largest percentage of plastics are produced by first-world nations.)

But these perceptions are only part of the story, and to get a balanced viewpoint we need to know the whole story. We certainly have much to do to address plastic pollution so that the above-mentioned benefits of these

materials can outweigh their drawbacks. So that plastics never reach landfill or incinerators but are instead recycled or reused. And indeed, many would argue that is exactly what governments, industries and individual companies around the world are doing. To name just a few, we have: the Ellen MacArthur Foundation’s (EMF) Global Commitment which has united more than 500 signatories; the posited UN Treaty on Plastic Pollution; and the Alliance to End Plastic Waste. There will be more on these later.

Then, of course, there are the many, many single organizations signing up to global commitments or looking at how they can individually tackle plastic waste. PakTech, a producer of 100% recycled HDPE handles and handle applicators, is one such company. Throughout this article, PakTech Sustainability Officer Gary Panknin will give us his viewpoint on the steps the industry needs to take, collectively and individually, to ensure plastics are not always seen as the ‘enemy’.

‘Unintended consequences’

“There is no question that plastic packaging and its impact on the environment is under scrutiny,” says Gary Panknin. “This has led to a public backlash on all things plastic.”

And one problem is, this ‘backlash’ can have its own unintended consequences if plastics are widely replaced with other materials without thinking about other factors such as carbon footprint or resource efficiency.

42 Packaging Europe

“We have seen knee-jerk reactions to this negative consumer perception of plastic – retailers and brands have been quick to switch to paperbased materials without reflecting on the low level of durability of paper, the fact that it can only be recycled a handful of times and that paperbased packaging often contains a lot of toxic chemicals and additives. Simply switching plastics to alternatives can lead to increased food waste, emissions and energy consumption.”

‘Three major challenges’

Before we go on, let’s acknowledge what the problem is and where the specific issues lie. PakTech sees three major challenges that the industry must address.

First and foremost, not all plastics are equal: Some types – such as PP no-bottle, PS or PET thermoforms – are not recyclable in practice and there are calls to reduce or cut their use entirely. Flexibles are also currently not recyclable, although as we know this is something the industry is working on, not least through the CEFLEX consortium.

“A lot of plastic packaging is not designed for recycling,” says Gary Panknin. “Some packaging uses two or more different types of plastic that make it difficult to recycle. Further, some types of plastic are much more difficult to recycle within the currently available infrastructure.”

For PakTech, it is also important to acknowledge that there is a big difference between ‘manufacturing with virgin petroleum vs using recycled plastic’.

The second major challenge for plastics identified by PakTech comes down not to the materials themselves so much as the wider infrastructure surrounding them. Plastic waste, to many, is a waste management problem. As Gary

Panknin says, there is a ‘clear mismatch’ between the demand for recycling and the current infrastructure available to support the industry and “many materials recovery facilities are lacking innovation to evolve with the demands of recycling. We are dedicated to pursing improvements in the recycling infrastructure to achieve improved collections and recycling of materials.”

Among other things, the industry needs to implement best practices when it comes to securing a steadier supply of PCR content, such as through long-term contracts. Alongside this, more viable reuse models need to be developed at scale through cross-industry collaboration on ambitious pilot projects.

And third, says Gary, “toxic chemicals or additives also pose a hindrance to recycling by reintroducing harmful substances to recycled products, and thus to the circular economy, or compromising the level of recyclability of a plastic material.”

43 Packaging Europe
“Toxic chemicals or additives also pose a hindrance to recycling by reintroducing harmful substances to recycled products, and thus to the circular economy, or compromising the level of recyclability of a plastic material.”

PakTech itself has attempted to address these three challenges through its own product design. It believes there should be more focus on the plastics that are widely recycled rather than attempting to create ways for more challenging plastics to be recycled.

“PakTech handles are mono-material as they are made from 100% recycled HDPE (#2 plastic). The material choice was deliberate as HDPE is one of the easiest plastics to recycle and also widely collected by kerbside collection. They are also toxic free, containing neither bisphenol-A (BPA) nor phthalates nor any other harmful chemicals.”

From problem to solutions

How, then, can the above challenges be addressed? One fundamental step to improve supplies of recyclates would be, as Gary says, “for the consumer-facing part of the value chain (such as retailers and brands) to commit to using more recycled material. This will help to drive more demand for recycled material, which would incentivize the improvement of recycling rates which in turn would make recycled plastic material more competitive compared to raw feedstock from fossil fuels.” The following infographic illustrates just how much we can save through improved recycling rates.

On a granular level, he feels there is plenty of promise and scope for innovation in the area of waste collection, sorting and separation. “For example, recently we have seen the integration of Artificial Intelligence to accelerate plastic waste classification in processing sites. This will allow the industry to work with secondary raw materials of higher quality. Also, automated recycling, which accepts, classifies and digitally bills for waste without the use of manual labour, could also benefit from AI solutions to address the worker scarcity plastic recyclers are often facing.” He adds that chemical recycling is likely to play an increasing role, but stresses the question marks that exist over the carbon footprint and chemicals required in the process.

We are seeing an increasing focus on the shift away from single-use to reusable packaging (as exemplified, for example in the EU’s Single-Use Plastic Directive as well as the key focus areas outlined in the recent EMF 2022 Global Commitment Report). PakTech believes this is an important goal – indeed, its own products are reusable – but cautions that we should not lose sight of the need to improve recycling processes.

“When it comes to reuse, it would be good to see requirements that are practical and without compromising on ambitions to build more recycling infrastructures. Our products provide a reusable alternative to single use and hard-to-recycling packaging such as plastic rings, plastic film or shrink-wrap.”

‘Are we moving in the right direction on plastics?’

While the industry must play its part through innovation and fundamental systems change, this has to be backed up by concrete laws and regulations. There are calls on governments – again, for example, through the above-mentioned EMF Global Commitment – to create legally binding plastic waste targets. It is of course a huge challenge to enshrine ambitious targets into law.

“For instance, in the EU, changing the legal basis of the Plastic Packaging Waste Directive to a Regulation is a very ambitious move as it means that the forthcoming legislation will apply equally to all Member States and also come into force at the same time for all Member States. However, this level of ambition is necessary to ensure that rules are harmonized everywhere at the EU level and circularity ambitions remain high for all Member States.”

With the global initiatives and treaties such as those mentioned at the start of this article, as well as ongoing policy and legislative updates, can we at least be hopeful that we are moving in the right direction on plastics?

Regarding the UN Treaty on Plastic Pollution, Gary Panknin says, “PakTech is glad to see partners joining the fight against the use of single-

44 Packaging Europe

use plastics, whether those partners are of a commercial nature like the businesses we work with or of a political or policy nature. The Treaty, which is expected to result into a legally binding agreement by the end of 2024, is expected to reflect diverse alternatives to address the full lifecycle of plastics, focusing on reusability and recyclability.”

The company is also a signatory of the US Plastics Pact, launched as part of EMF’s global plastics network (of which PakTech is a signatory). Many in the industry will already be familiar with the main goals of this, but just to briefly recap, the pact aims to: eliminate problematic plastic packaging by 2025; ensure 100% of plastic packaging is reusable, recyclable or compostable by 2025; achieve an average 30% recycled content or responsibly sourced bio-based content in plastic packaging by 2025; and undertake actions to effectively recycle or compost 50% or plastic packaging by 2025.

All these goals are vital and it has been encouraging to see such impetus behind systemic change. However, as outlined in the recent EMF 2022 Global Commitment Progress Report, it is becoming increasingly likely that these targets will not be reached. This, says the Foundation, only ‘reinforces the urgency for businesses to accelerate action, particularly around reuse, flexible packaging, and decoupling business growth from packaging use’.

This signals that, while individual signatories may be on track to meet the targets, as a collective, the industry and governments need to do better. I was interested to know where PakTech feels some of the issues may lie, and how the agreement may perhaps be modified to ensure a more positive outcome. For Gary Panknin, it comes down partially to a recognition that in some ways we are not all equal and that perhaps goals should reflect this (not, admittedly, an easy to thing to accomplish when taking into account the amount of work it takes to bring such a global commitment into being in the first place).

“We need to look at sustainability holistically, and at the same time, we have to take into consideration the specific requirements of individual companies in a flexible way. There is no one-size-fits-all solution in existence. It is mandatory to constantly evaluate which activities make sense for a certain company to achieve concrete, significant, and noticeable sustainability improvements in the best way. Increasing the use of recycled plastic can be a great lever for one company to increase sustainability. In contrast, for another company, this can be irrelevant because of constraints in terms of technology or restrictions from the products that will be packed (e.g. food contact packaging).”

‘The real enemy: Failure to act’

Are plastics the enemy? It may sometimes appear that way but, as with many if not all problems, small or (in the case of climate change and plastics waste) unfathomably large, failure to move is the real enemy. Given their relatively low carbon footprint in terms of production, plastics can indeed be part of the solution to our current climate crisis, if we can move away from petroleum-based materials and reduce reliance on virgin plastic, while simultaneously boosting reuse and dramatically increasing recycling rates. And it’s also worth pointing out, as many have, that the need to reduce CO2 and tackle plastic waste do not have to be mutually exclusive goals.

There is certainly reason to hope when it comes to achieving a circular economy for plastics, but as they say, hope can be cheap. It is actions that propel us forward. n

PakTech – Putting circularity principles into action

• The recycled HDPE PakTech uses to manufacture its handles is made from products such as milk, water, juice, and other unpigmented household containers.

• Production of PCR plastic material compared to virgin plastic material requires 90% less energy, 100% less petroleum and produces 78% less GHG at the processing facility.

• PakTech handles are designed for recycling and once recycled, they are given a third life as composite lumber, park benches, planter pots and more.

• 907,164,295 recycled milk jugs have been collected, shredded and extruded into pellets to create PakTech products.

• 54,429,858 kilograms of plastic has been rescued from landfills and oceans and used to make PakTech products.

• The equivalent of 25 soccer fields were saved from landfill by repurposing recycled containers into PakTech products.

DIGITAL PRINT: HOW FAR DO WE STILL HAVE TO GO?

When it comes to digital printing, how far have we come and what can the industry do to take advantage of the many benefits these technologies offer? Victoria Hattersley reports.

Are we there yet?

Anyone who has driven a child on a long journey will no doubt be all-too familiar with the question. When we apply this question to digital printing, as in, have we reached the stage where it accounts for the largest percentage of the market, the answer really depends on what ‘there’ means.

According to the Smithers Pira report, ‘The Future of Digital Printing to 2032’, by 2032 digital print will account for almost a quarter of the global value of all print and printed packaging by value, so we’re certainly not looking at total market saturation. In short, it appears we’ve still got a way to go (sorry, little one).

Then again, perhaps the child-on-journey scenario is not the best analogy at all. Perhaps we need to think of the road to digitalization of printing as not so much as one with a finite end, as a series of stops – a gradual progression of technological breakthroughs in print machines, workflow and finishing systems that bring us further along the road to mass digital adoption.

In the following, I will highlight four key drivers for progress in digital printing: sustainability, easing supply chain pressures, meeting consumer needs and meeting brand owner needs. I will look at how digital print can help to address, these including some recent examples on the market –and then, perhaps more importantly, how far there is still to go.

Key drivers 1. Sustainability

Sustainability – or lack thereof – is the biggest concern for every aspect of the value chain. There are several ways in which digital already has an environmental advantage over analogue. Patrick Poitevin, former Principal Scientist at Mondelez International and founder of Advisory4Pack, mentions just a few of these.

“Inventory reduction is an important factor: Instead of eg. 60 SKUs with digital you would only need one for each brand. There is also no obsoles-

Packaging Europe 47

cence: you only print what you need, when you need, for where you need; this is the case not only for packaging materials, but also when there are changes to the finished product due to overstock; changing legislations or ingredient changes can be factored in. Finally, digital print engines also use less energy than their conventional print processes, as well as well less ink.” We can add to this the fact that a significant amount of energy is required to produce offset plates, whereas with digital, no plates are required.

A recent example of the impact innovative digital technologies can have on brand owners’ environmental footprints can be found in the finalist list of our very own 2022 Sustainability Awards. CCL Label’s Hybrid ASD Technology enables printing embellishments to be produced with digital hybrid inkjet technology. According to CCL, it provides ‘”all the embellishments of conventional printing with digital hybrid inkjet technology. It is designed to reduce waste, reduce CO2 footprint, and use less material and solvents whilst using less energy during the print process. This ensures brand owners still have the freedom to design without limitations.”

2. Ease supply chain pressures

In today’s global marketplace, changes in consumer expectations have vastly increased the pressures on the packaging supply chain. Digital print can play its part by, among other things, offering a quicker response to the market, shorter lead times, inventory reduction, increased efficiency and minimum order quantities (MOQs).

Sealed Air, for example, has launched a digital packaging brand, prismiq, which has a portfolio of solutions for design services, digital printing and smart packaging. Through this, systems can run multiple designs on a single order, print serialized/digitized codes and images that are packagespecific and allow customers to have flexible order quantities, as well as, it claims, faster turnaround times.

“Our world is constantly changing and evolving,” says Amir Shalev, Director of Market Development at Landa Digital printing, “and our printed products need to be able to change with it and keep up with the pace. Digital printing enables service providers to cut down their response time for their customers. On top of that, the reduction in setup times and make ready means that we can take away the inefficient pieces of the production schedule and release tremendous capacity to let the conventional, analogue presses become more productive – and overall, increase plant yield.”

3. Meet consumer demands

The key goal of brand owners – apart from sustainability – is to meet consumers’ evolving demands. Increased interest in personalization and customization are central here, as Patrick illustrates: “More and more brands utilize digital print for unique individual customization for events - eg. Cadbury’s Dairy Milk associated with football tournaments, Toblerone’s continuous personalization which can be done in store, in airports where growth and market increase is obvious. The HP Mosaic is well known and used quite often for customization.

Packaging Europe 48
Sustainability – or lack thereof – is the biggest concern for every aspect of the value chain and digital print is not exception. There are several ways in which digital already has an environmental advantage over analogue.

Also, brands such as Mondelez International’s Milka have enabled the possibility for consumers to individually colour or create their own design and have their packaging (product) printed.”

Furthermore, as consumers are much more concerned with both the provenance of the products they buy and what they contain, it is also important that brand owners can communicate information to them in the most efficient way. This includes personalized ingredients and wellbeing information, sustainability messaging and communication. All of this is a substantial improvement on offset if there are ingredient or legislation changes that need to be incorporated on the packaging at a late stage.

4. Meet brand-owner needs

For brand owners, the onus is very much on factors such as security, brand protection and image. Digital presses such as HP’s Indigo 6K Secure Press can address the first of these. The machine was designed specifically for the security printing market, delivering end-to-end security solutions featuring multi-security layers printed in one pass.

When it comes to the look of the pack, digital print also opens up opportunities for more higher-resolution graphics than was formerly possible, helping ensure brand stand-out.

“Digital vendors are constantly improving their systems to address a larger piece of the addressable market,” say Amir Shalev. “Landa Digital Printing’s Nanography® is a platform that allows endless upgrades for productivity, print quality and application span.”

‘Keep pushing productivity’

All of the above shows us what is currently possible. But it is fair to say that the market has not yet fully embraced the opportunities offered by digital printing technologies. So where are the missed opportunities, what can the industry do better and what are some of the challenges to overcome?

On the one side, the wider industry downstream – the brand owners, retailers etc. – have been slow to embrace the benefits of digital. “What has not been done enough is to bring digital print in-house, in line, near line - which creates even more opportunities in regard to inventory control,

49 Packaging Europe
50 Packaging Europe

reduced obsolescence and sustainability,” says Patrick. “But,” he emphasizes, “product makers are not printers. So good and close collaboration with digital print converters is essential.”

But there is also a need to drive technology forward further upstream, on the innovation side, as Amir Shalev tells us: “Digital printing is on its way to becoming mainstream. However, providing the unique digital capabilities of just in time printing and variable data is not enough. Digital vendors will need to keep pushing productivity, media compatibility and print costs to constantly grow digital volumes by working on both sides of the equation – which are volume and value printing.”

To ‘do better’ also involves pinpointing and addressing the most significant challenges or barriers to wider digital print adoption. We are familiar with the issue of food contact compliance when it comes, for example, to recyclates – but the same issue applies to digital inks. As Patrick tells us, there are not many digital print inks or processes that are fully compliant with EU or global legislation. On a more positive note, in the future it is expected that more and more digital inks will become food compliant.

“Cost is another a challenge,” he says. “But that is because brand owners compare like for like when it comes to packaging materials. And they do not compare and incorporate other cost benefits such as inventory, obsolescence, speed to market, test markets and so on. Then there is speed. Where conventional print is up to 500 metres a minute, inkjet or electro inks are still slower.”

‘No final destination, just progress’

But what about the road ahead? What are the up-and-coming technologies or trends that we can expect to make a real difference for the packaging value chain?

One thing that’s coming next, says Patrick, is print on shape, where “a product will be able to be printed once packed or even shipped, which leads to greater flexibility and opportunities at later stages – at warehouse, at retail, in vending machines, stores or airports.”

From a wider perspective, says Amir, “Expect to see a continuing push by digital vendors in the packaging space. We could have the market include smaller, low-cost systems aimed at very short runs and small customers, to larger, industrial digital presses that will take on the larger volumes and aim for the bigger production plants.”

Before we get too excited about the prospects for digital we should remember that embracing newer technologies does not necessarily have to mean that the more established ones become entirely obsolete – rather that the ratios gradually change over time.

“Digital print will and should never be considered to replace conventional print,” confirms Patrick. “It is an additional process which can be integrated as hybrid presses or should be utilized for the right reasons, the right opportunities.”

Yet there’s no doubt that the pace is picking up for digital. Expect to see its market share grow, and look out on packagingeurope.com for stories of new product and technology launches in the coming months. n

A CLOSER LOOK AT BW PACKAGING’S PEOPLECENTRIC APPROACH TO PACKAGING INNOVATION

What does it mean to take a people-centered approach to value creation in the packaging space, and what are the core benefits of using a system like this? Barry-Wehmiller’s VP of Innovation, John Koke, explains how BW Packaging views innovation as an opportunity to include customers in its culture of caring for people.

The statement “We measure success by the way we touch the lives of people” underpins Barry-Wehmiller’s guiding principles. Could you introduce this concept to our readers? What does it mean in practice?

Barry-Wehmiller’s people centric culture originated with our CEO Bob Chapman who saw that business could be a fundamental force for good in the world if companies genuinely cared for their people, treated them with respect, and built a vibrant business able to provide a secure future for them and their families.

Within BW Packaging, our vision is to ensure that everyone who interacts with our team, our equipment and our parts feels that same level of care. We touch the lives of tens of thousands of people every day as they operate and maintain the equipment in their operations.

What are the core benefits of a people-centric innovation model, and what does it offer that other models don’t?

People centric innovation grounds our new product developments in fundamental value creation in the lives of people. What are the needs of the operators who use our machines every day? What are the needs of the maintenance teams that are responsible to keep our systems in great working order? What are the needs of operational leaders? And what about the needs of the business leaders who count on our machines to safely package their products day in and day out? What can we do in packaging to help marketers to market their products more effectively? A peoplecentric innovation model challenges you to consider value creation from a people centered point of view.

And how does the ethos of people-centric innovation manifest itself at BW Packaging on a day-to-day basis?

Our innovation process now starts and ends with people and markets. We start our innovation process with a deep dive on customer needs. We conduct voice of customer events to speak with people who rely on our products and services to do their jobs. What are their needs? How can we better address those needs? And we don’t stop there. Several years ago, we decided to train our team members to perform true observations, to go and watch our customers or potential customers use the equipment that they have today to identify the aspects of that experience that could be improved that they might not think to tell us in a conversation because they are so accustomed to living with that constraint.

It is not just about designing the machine; it’s about understanding how we impact customers in every interaction with us. This includes the sales process, the installation, and the entire life cycle of our packaging solutions in their plants. How can we solve their problems? How can we create value for them?

Could you pick out a specific project or product where people-centric innovation is particularly evident?

We recently introduced the Hayssen ISB VFFS Bagger in our BW Flexible Systems Division. This is a great example of people-centric innovation and it’ll be on display and running at our Interpack stand 6/C79. This solution was designed to be used in the high hygiene applications like produce, cheese, and IQF. These are typically harsh environments to work in, not only for our machines, but also the people who operate them.

We sat with the people who work on our machines in these environments and asked them: what made their tasks difficult? What was hard? What would an ideal solution look like from their perspectives? Then we sent our engineers and cross functional teams into our customers’ operations to observe their current machines through a 24-hour cycle: Start up, production, change over, breaks, restarts, shut down, 3rd shift wash down. All in the pursuit of understanding what problems we could solve for the people who worked on our machines day in and day out. Only when we had collected and synthesized those insights did we set out to design our solution.

What would you say to a company that is debating switching to a model like this? What could they stand to gain?

I suspect BW Packaging was not so different from many companies. We had a history of basing our innovation efforts on bringing great new technologies and systems to markets. Someone would have a great idea; they would sell that idea to leadership. We would invest and develop a great technological marvel. The only problem was no one needed it.

It was not addressing the real needs people have while running a packaging line every day. People centric innovation focuses your value creation at a very human level. Creating real value for customers, real people with real jobs, hopes and dreams, and not to forget, shareholders who are real people too. n

MAKING THE CASE FOR ANTIMICROBIAL PACKAGING FILMS

Innovative antimicrobial and antibacterial materials are announced on a near-weekly basis, but why do so few reach scale? What can the industry do to commercialise more solutions like this in a cost-effective, viable way? Andrew Manly, communications director at AIPIA, tells us more.

Over the last decade (or more) AIPIA has reported on the development, or research into the development, of hundreds of active packaging materials – intended to fight microbial or bacterial growth – to extend the shelf life and maintain the condition of perishable foods and some sensitive pharmaceuticals.

These projects are using a host of materials, which range from bamboo to cellulose on one hand and cranberries to durian skins on the other. Add to that an extensive mix of more exotic materials, such as nano mud, chitosan, and essential oils of many herbs, and you have the potential to be confused. l am, for sure. At the end of the day, it’s got to be about effective food waste prevention.

Let’s be clear from the outset, there are some highly successful active materials on the market - whether additives, coatings or compounds, from highly reputable companies such as Aptar, Parx, and Sealed Air; to name just three AIPIA members in this space.

My confusion arises from how many different materials researchers actually need to explore to come up with what is needed. Again, our members

such as AIMPLAS and ITENE are doing great work here, often in collaborative projects with industry partners.

But when researching one story l came across no less than 200 different university research programs developing some form of antimicrobial or antibacterial packaging film.

Research is, of course, necessary – you may have to go down many avenues before you find the right path. My issue is, after more than a decade, why have we not settled on four or five promising materials which have the right properties and focused our attention on these?

What is needed are effective, scalable materials or additives which are costeffective and meet most sustainability criteria (recyclability being a key one).

I am not a scientist, but over the years one or two materials, such as cellulose or chitosan (the shells of shrimps and lobsters and other crustaceans) have shown great promise and have the advantages of being plentiful, easy to source, and highly cost-effective. There would seem to be a sound criterion for using them as the basis for ongoing research and development and, l emphasize again, at scale!

Nanomaterials have also shown themselves to be highly effective antimicrobial agents and, in the right combination of compounds, can have dramatic beneficial effects. AIPIA worked with several partners on the NanoPack project, funded by the EU’s horizon 2020 program.

In three years, we developed a very effective plastics packaging film using halloysite nanotubes combined with oregano and thyme essential oils. The resultant film proved able to inhibit mould growth in bread by at least three weeks; increase saleability of fresh cherries by 13%; and expand shelf-life of yellow cheese by at least four additional days.

55 Packaging Europe
56 Packaging Europe

However, any commercialization of this, or any other, food contact material is stalled by the need for regulatory approval, in the EU by ESFA. But this can take years, which makes most industry-funded projects unattractive. This is a major barrier to developing active food contact materials beyond the laboratory, in my opinion, and needs to be cleaned up urgently, both here in Europe and in the USA’s FDA. We all want them to do their job, but not take forever about it.

Food (and pharmaceutical) waste is now at the top of the agenda item for governments, NGOs and affected industries. Of course, the sustainability factor is also part of this equation – hence the focus on using naturally derived materials for these antimicrobials and antibacterials. But let’s not forget food waste is a bigger environmental problem than packaging waste.

Given the amount of food that continues to be wasted and both the monetary and environmental cost of it, there would seem to be an urgent need to encourage the development of more active packaging films. There needs to be more joined-up thinking on what to develop and encouragement from Governments and other organisations to speed up bringing these to market.

If produced at scale it would cost tiny amounts per pack to implement. As one AIPIA member said to me: “If you can reduce wasted food, extend selling time, and increase profitability along the supply chain it’s a no-brainer! Why would you not want to do that?” Answers, as before, on a postcard….

This article was created in collaboration with AIPIA (the Active and Intelligent Packaging Industry Association). Packaging Europe and AIPIA are joining forces to bring news and commentary about the active and intelligent packaging landscape to a larger audience.

To learn more about this collaboration, join us at this year’s Sustainable Packaging Summit and AIPIA World Congress in Amsterdam this November from the 14th to the 15th).

WHAT DOES IT MEAN TO ‘INVEST IN BETTER’?

Klöckner Pentaplast, a global manufacturer of plastic films and high-barrier protective packaging, has set out an overarching aim for the business – ‘Investing in Better’. By achieving concrete targets related to this aim, kp hopes to lower its environmental footprint, improve the lives and careers of its employees, and make a positive impact on communities.

We spoke with Ben Elkington, Marketing Director for Global Trays at kp, to learn more about this initiative – and how it relates to the products the company will be demonstrating and launching at interpack.

Simply put: what does ‘Investing in Better’ mean to kp? How is it reflected both in overall goals and on a day-to-day basis?

We are investing our time, focus and energy in becoming a better, more sustainable business.

kp’s purpose is to deliver the sustainable protection of everyday needs. It means we incorporate sustainability into everything we do.

Our broad and ambitious sustainability strategy drives us to design new, recyclable products and to close the loop by using more recycled material in their production.

We are also focusing on becoming more efficient, cutting carbon emissions, and helping our customers and end-consumers play their part. Working with others to make our industry more sustainable is critical, as is making sure our people are safe, mutually respected and engaged as they help us do better.

Our sustainability strategy, ‘Investing in Better’, comprises three clear objectives and ten specific targets:

Objective 1: Close the Loop

Many of our Food Packaging products already contain 100% PCR and have done for some time.

By 2025, at least 30% of the post-consumer recycled material in our packaging will come from our kp Tray2Tray® initiative and 100% of our packaging will be recyclable.

Objective 2: Work Smarter

With the aim of using less energy, we will increase energy efficiency by 17% against a 2019 baseline by the end of 2025, we will reduce Scope 1 and 2 emissions by 50%, and by 2030, Scope 3 emissions by 20% per tonne of raw materials, against a 2019 baseline.

Objective 3: Act Responsibly

In the future, we will do even more to keep our people engaged, while we become a safer and more diverse company.

By the end of 2025, we will reduce our lost-time accident rate to zero, the percentage of women at management levels at kp will exceed 30%, and our employee engagement score will improve to over 80%.

100% of kp plants will complete at least one impactful community project annually, doubling that by the end of 2025.

I’d now like to drill down into the concept as it relates to different sustainability themes. What does ‘Investing in Better’ mean to kp in terms of recycled content and Circularity in general?

We have been using post-consumer recycled PET for nearly two decades to produce high-quality products that meet global safety standards and consumer expectations. We are maximising the recycled content across our product lines – replacing recycled content from bottles with recycled content from trays is at the heart of – our kp Tray2Tray® programme.

58 Packaging Europe
kp FlexiFlow® EH 145 R & kp Infinity®

50% of PET used in Europe is recycled – most of it coming from plastic bottles. 30% (500k tonnes) of the total available recycled PET goes into food packaging trays. And virtually nothing is recovered from used trays. That means 500k tonnes of tray PET is wasted per year! After three years of research, we have developed a solution.

Our kp Tray2Tray® technology creates a closed loop for trays. Our work with the entire value chain is helping to generate demand and ensure a constant supply, the success of which depends on suppliers providing kp with adequate quality tray flake, on recyclers maintaining their investment in tray recycling, and on customer demand at the right scale. Thanks to the kp Tray2Tray® programme, our plastic trays and rigid films can now come back time and again as safe, protective, fully recyclable food packaging trays, in a fully closed loop.

Tray2Tray on its own has the potential to bring more than 50k tonnes of recycled PET back into the game.

How about recyclability – how is ‘Investing in Better’ manifested in that area?

We are committed to increasing the recyclability of our entire product portfolio. We are transitioning from multi to mono layer packaging and innovating to remove difficult to recycle elements from the packaging.

Our kp Zapora® padless tray technology improves recyclability. Our product designers have worked out how to deliver high-quality fresh protein packaging while doing away with absorbent pads and their adhesive, both of which have the potential to contaminate streams.

This helps improve the operation of kp Tray2Tray®, as obtaining highquality flake becomes easier, and more can be included in our mix.

kp Zapora® is cleaner and more convenient for the end consumer to recycle at home. The trays are already made using up to 100% recycled PET in a mono-material which is available to packers globally. Removing the pads means greater process efficiencies, and easier handling for recyclers.

It is also available in combination with both kp Elite® and our Mono rPET trays.

kp Zapora® won three awards in 2022: Global Pack awards Best in Class, World Star Award, European Congress United.

kp Elite® is a modified atmosphere packaging (MAP) tray for fresh protein that delivers end-to-end sustainability. It’s an award-winning product made with up to 100% recycled post-consumer PET (rPET), which is recyclable. It is highly efficient, reduces food waste and extends shelf life.

We will be rolling out certified recyclability (RECYCLASS) for our kp Elite® product line in 2023. It can be combined with our kp FlexiLid® EH 145 R product as a certified recyclable solution for MAP case ready applications.

kp MonoSeal® is a mono PET film that is fully recyclable and that has the strongest sealing capability in the market, while being 7% lighter than multi-layer films. It also offers best in class hermetical seal, even through

contamination. It’s downgauged 10% and so the rolls are longer requiring fewer reel changes for the customer and energy gains because it seals at a low temperature. kp MonoSeal® has gained certification of recyclability by TCEP (Tray Circularity Evaluation Platform) from PETCORE Europe, being one of our first rigid film products truly closing the loop.

kp FlexiLid® EH 145 R is recyclable barrier top lidding film. We combine the kp FlexiLid® EH 145 R formulation of our flexible barrier top lidding film with our sustainable trays and technologies to create a recyclable combination from top to bottom. With this combination you get a top film with best-in-class blown extrusion technology and an award-winning tray together from one source.

kp FlexiLid® EH 145 R is certified and validated by the third-party organization Interseroh and designed following Ceflex recycling guidelines.

Meanwhile, kp FlexiFlow® EH 145 R is our recyclable barrier flow wrap film which delivers full protection while minimising plastic weight up to 75%. It’s the perfect sustainable solution for minced meat. Combine it with our fully recyclable, mono material kp Infinity® trays to create a recyclable combination all around. With this combination you get a flow wrap film and an award-winning tray together from one source.

And what does the concept mean in terms of resource efficiency? What are your views on the importance of making the most of limited resources in a sustainable way?

We want to play our part in tackling some of the big environmental challenges the world faces today. Reducing resource use, cutting emissions and avoiding landfill helps us do that.

It’s a balance between material reduction and protection. We engineer our products to ensure effective protection and preservation of food. At the same time we need to guarantee that the products we manufacture can run on our and our customer’s lines efficiently.

Energy saving initiatives are also part of our strategy. We have invested in on site solar energy in several sites and will continue to do so. We make and generate our renewable energy at or near these sites. n

FOCUS ON FIGHTING FOOD WASTE

The SAVE FOOD initiative was set up to battle the global food waste crisis. At interpack 2023, a new pilot project with the goal to produce biodegradable food packaging from food waste or from by-products of food production will be presented. Elisabeth Skoda speaks to Bernd Jablonowski, Executive Director at Messe Düsseldorf, and Zeynep Tacer Caba, PhD , Assistant Professor, Faculty of Engineering and Natural Sciences, Bahcesehir University, Project Co-ordinator, to find more about the work of the initiative, important milestones and the latest project.

Elisabeth Skoda: Could you tell me a bit more about the history of the SAVE FOOD project – when and why was it set up, and what are its goals?

Bernd Jablonowski: The SAVE FOOD project was founded in 2011 by Messe Düsseldorf, interpack, and the Food and Agriculture Organization of the United Nations (FAO) in response to the growing global food waste crisis. The project recognizes that reducing food waste has a significant impact on the environment, as wasted food is a major contributor to greenhouse gas emissions and the depletion of natural resources. Moreover, it exacerbates hunger and poverty, making it a critical issue for both developed and developing countries. The goals of the SAVE FOOD project are multi-faceted, including increasing public awareness about the issue of food waste, promoting the development of new technologies and best practices to reduce food loss and waste, and supporting the development of international and national policies and programs to tackle this issue. Certainly, with interpack, we can bring in our special expertise and network in the global processing and packaging industry, as innovation is key.

What are some of the notable milestones of the project?

BJ: Through various initiatives such as congresses, meetings, studies and presentations, e.g. at the UN, the initiative has succeeded in raising

awareness of food loss among different actors in the value chain. This has led to the formation of alliances and individual commitments, resulting in concrete solutions and projects to reduce food loss.

One such project is the Mango Project in Kenya, where SAVE FOOD members worked with a local company to process fresh mangoes into dried fruit and pack them hygienically. Previously, up to 64% of the annual harvest was lost because the mangoes could not be harvested and processed in time.

Despite the successes of the initiative, there is still a long way to go from creating awareness to changing behavior and implementing concrete projects. During Covid, the project was put on hold, but since last year we have been actively tackling projects again. At the moment there is a joint study with the Bahçeşehir University (BAU) in Istanbul. The goal is to produce biodegradable food packaging from food waste or from by-products of food production.

60 Packaging Europe
The SAVE FOOD project recognizes that reducing food waste has a significant impact on the environment, as wasted food is a major contributor to greenhouse gas emissions and the depletion of natural resources.

How did the collaboration BAU Istanbul come about?

BJ: The initiative came from our long-standing partner, the FAO Regional Office for Europe and Central Asia, who brought us and BAU University together in a partnership. This collaboration is set up as a student challenge on a new food bio-packaging solution using food waste/food by-products to be developed and named "Bio-based packaging using food waste student challenge - SAVE FOOD Initiative Messe Düsseldorf GmbH & BAU". The project partners are BAU, Messe Düsseldorf GmbH and CIFAL Istanbul, UNITAR. The two selected concepts will be presented at interpack in May.

Who are the participants in the pilot project, and how are they working together?

Zeynep Tacer Caba: We have recruited 28 students for the study. They work in six interdisciplinary groups. The students come from the Bioengineering and Biomedical Engineering MSc programmes as well as Industrial Design, Industrial Engineering, Computer Engineering, Molecular Biology and Genetics, Electrical/Electronic Engineering and Energy Systems Engineering. So, we have a wide range of expertise and special experiences and approaches. A great combination! They have taken intensive courses in food packaging, materials science, design thinking and nanotechnology applications. With this project, they are learning by doing and gaining a deep understanding of a novel food packaging development process.

Looking a bit closer at the project, what are the key challenges that need to be overcome when developing biodegrad able packaging from food waste and food by-products?

ZTC: Food bio-packaging solutions require a multi-layered evaluation of different issues. Therefore, the main challenges were related to the creation of novel user-based bio-packag ing ideas, the selection and safety of food waste, difficulties in learning, designing and conducting the experiments, challenges in working in multidisciplinary groups and planning the sharing of responsibilities.

How are you overcoming these challenges?

ZTC: When faced with challenges, the initial solution is often linked to research, as it provides a better understanding of the problem at hand. In addition, challenge-based problem-solving methods can be developed on a product-specific basis. When dealing with in-group problems, it is crucial to use the appropriate communication tools to ensure effective collaboration and problem resolution. However, it is important to note that the challenges we face are complex and multifaceted, and thus require a multidisciplinary approach to design and build vision and strategy.

Could you tell me a bit more about the prototype that will be presented at interpack 2023?

ZTC: From tea waste to banana leaves - we see many exciting approaches. But currently I can only give you the status of the process. We do not yet know which idea will make it to the final round. Two of the following ideas will be presented at interpack: SCOBY biofilm with tea waste as a novel packaging for dried foods, PLA and rice husk integrated nano-film for the modified atmosphere packaging of strawberries, 3D printed pectin film for confectionary, double layered packaging from banana leaves, mussel shells, and watermelon rinds, Nano-film with pomegranate peel for meat packaging and Beeswax coated inner case for milk packaging. We are curious to see which approach will show the greatest potential.

Can you give us some examples of innovations on show at interpack that address the issue

At interpack, we have around 30 exhibitors who are also members of the SAVE FOOD initiative. This is great news because the SAVE FOOD highlight route at the trade fair allows visitors to get a glimpse of the latest technologies that can help reduce food losses and increase product safety. Additionally, we've included the SAVE FOOD topic in our lecture programme, particularly during our product safety theme day at the spotlight forum talks & trends. n

DISCUSSING SUSTAINABILITY IN FLEXIBLE PACKAGING WITH WIPAK

In the latest edition of our ‘In Conversation With…’ feature, we spoke with Wipak’s Senior Marketing and Communications Specialist, Josefina Pönkkä, to unpack their views on how the evolution of regulation and consumer sentiment is affecting the flexible packaging sector.

How have changing regulations affected the flexible packaging industry?

The changes of regulations in packaging are mostly driven by environmental concerns over their impact in addition to safety reviews about the packaging materials, and companies must comply with these changes.

Other topics driven by regulation and consumer awareness is the aim to reduce plastic materials, design for recycling, re-fill solutions, etc. all with the aim of enabling a circular economy where materials are responsibly sourced, recycled and recovered back into production always aiming to reduce waste as much as possible throughout the entire process.

Nowadays there are strong guidelines urging to keep end-consumers well-informed so that they can take responsible purchasing decisions. The recyclability of the packaging must be considered as early as the design stage considering the user experience providing all the necessary information so that the packaging may be effectively sorted, collected, and recycled. Countries following different approaches to these guidelines, makes it even more challenging, therefore we keep preparing ourselves to stay up to date on trends, regulations, and certifications.

For example, we make sure our renewable and recycled materials are from certified and traceable sources: all our paper materials are from responsibly managed forestry and our recycled materials are ISCC plus certified.

Consumers are becoming more environmentally conscious, and flexible packaging has come under fire for not being so easily recyclable. What effect did this have on the industry?

A ground basis to participate in Ceflex as stakeholder is to support a common approach on design for recycling guidelines that ensure effective recycling for flexible packaging. This connects directly to the previous point on consumers making informed decisions by having access to information that should be clearly displayed on the flexible packaging.

The flexible packaging industry works closely among the value chain partners to ensure flexible packaging is designed to meet with recycling requirements and that their formats and solutions are collected, sorted, and recycled across all EU countries.

What are the biggest sustainability challenges when it comes to developing flexible packaging?

The flexible packaging industry has continuously focused on reducing material consumption for decades. There are several challenges when trying to reduce plastic material for thinner and more lightweight packaging that also meets design for recycling guidelines. The ideal scenario is that there would be recycling infrastructure and technology that can

effectively allow recycling of at least 80% of all flexible packaging, that’s what we aim for in Ceflex.

As there are limitations and local guidelines on what can be classified as recyclable, our solutions must be designed for recycling from the start to be compatible with the waste streams. A common approach in designing for recycling in Europe would be possible with upcoming legislations, resulting in better aligned schemes.

In 2019, Wipak committed to becoming the first climate-neutral flexible packaging company by 2025. How far along is the company now, at the halfway point of this journey?

Our main target to reach Company Carbon Neutrality by 2025 has not changed. We know our journey will not come to an end by this time but will be the strongest foundation to our never-ending pledge to reduce our emissions to the constant absolute minimum. We are thrilled to have reached the big milestone of becoming Operational Carbon Neutral by the end of last year.

Our operational carbon footprint describes all Scope 1 and 2 emissions in Wipak’s authority. Those include all energy related emissions as well as further direct emissions (cooling mediums, burning of solvents (RTO)). All our production units are running on renewable electricity, and we have on-going energy-saving projects across all our sites.

One of the strongest pillars at Wipak has always been our focus on avoiding waste. During 2023, one of the key activities is the optimization of our internal recycling capabilities across all units. Some other carbon reduction projects include further investments to using bio solvents and transitioning to water-based inks and adhesives.

We believe in our strategy, and we keep on constantly preparing for the future. We are aware that there are some small unavoidable remaining emissions. These emissions are offset by founding certified carbon reduction projects to reach carbon neutrality.

Is GreenChoice by Wipak a pillar to this strategy?

Wipak is committed to becoming the most sustainable flexible packaging company, and we are on the right track to reducing our Company carbon emissions to zero by 2025.

We measure and report direct emissions caused by sources under Wipak’s authority as well as indirect emissions from upstream and downstream activities from Scope 2 and 3 that are not in Wipak direct’s control. Our infinite goal is to minimize emissions from all our company’s activities to the strict minimum, including those related to our products.

However, the corresponding emissions to the use of the flexible packaging material produced by Wipak has a variety of options at every customer. Nevertheless, we are constantly developing and introducing innovative flexible solutions that comply with the market demand and the changing regulations, highlighted under our GreenChoice portfolio of flexible packaging solutions.

GreenChoice by Wipak is our pledge into actions by making the transition in favour of more sustainable flexible packaging as easy as possible. With GreenChoice, we offer solutions that are recyclable, from certified recycled or renewable feedstock. In our efforts to reduce carbon emissions, we use for example our WContribute software as a comparison tool for calculating the carbon footprint of various solutions to help the customer in making well-informed decisions. n

RECYCLING BY COLOUR ON SECOND THOUGHTS...

The EU’s recent adoption of a 55% net emissions reduction target by 2030 has sent a clear message across all industry sectors, but it is the waste sector in particular that needs to heed the call given that it has been listed among the largest contributors to Greenhouse Gas Emissions (GHG) in the EU. According to a report by Eunomia the waste sector emitted 112 MtCO2e (million tonnes of CO2 equivalent) in 2020 .

This reinforces the urgent need to address the end-of-life management of all waste, starting with post-consumer packaging.

As I write we face pivotal societal choices that risk destabilising our best efforts.

There is a disconnect between those who steadfastly believe there is no need to change their modus operandi because technology will resolve our issues and those who acknowledge that technology is only one part of the equation. In truth we don’t need over-complicated solutions to close the loop, we need manageable, accessible and scalable solutions.

And these do involve a degree of change that can be simply and cheaply adopted- namely in the way we address packaging design.

Packaging decision-makers should clarify what their end goal is for their packaging. This must now go beyond protecting and marketing the goods contained within. Priority should be given to the end-of-life of the packaging – all packaging must be capable of being effectively sorted by recyclers with minimal adaptation.

Colour controversy

Pigments are possibly the most contentious element of today’s packaging. Yet, if we could shift the rigid mindset around colours = branding and instead opted for colours defining specific categories, we could transform packaging into a recycler’s dream come true.

In this scenario only a small range of colouration systems would be acceptable – such as all food products contained in natural or white packaging, brands in the non-food sector in pastel colours – thereby using smaller concentrations of pigments – and hazardous products in black plastic to ensure they don’t enter domestic recycling circles.

Sorting by transparent/pastel/black colouration of packaging is simply achieved by deploying established, accurate and relatively low-cost auto-

matic sorting technology using the visible light spectrum and cameras for detection.

If we take this scenario further all automatic and manual sorting systems could immediately adopt this protocol globally without delay and without expensive capex or plant alteration. The sorting speed and yield would be boosted due to its simplicity, the purity of food-grade packaging could be instantly assessed and quantified and as recycled content levels rise the cost for high-quality recycled material would drop.

Shedding pack colours would reduce masterbatch costs. The design cues could be on the label (with self-peeling or dissolvable glue) or sleeves. This simplifying scenario would result in effective separation of foodgrade plastics without expensive and complex sorting equipment. It would also boost recycled content levels, making high-quality recycled material more plentiful and less expensive.

And, finally, the actual brand recycling story would be authentic.

Ultimately coloured plastic packaging is much harder to recycle economically than clear plastic since there is little demand for the resulting “recycling grey” that we get when we mix colours.

If brands aligned with their sustainability targets by relinquishing their reliance on branding by colour, the recyclability of their packaging could be transformed.

Busting the technology myth

The reluctance to make this quantum leap is primarily due to our all toohuman resistance to change – and the flawed perception that technology is a cure-all that will enable brand owners to continue producing packaging without any changes – like developing a high-tech sledgehammer to crack the proverbial nut.

In fact, if we create multiple sub-categories of packaging in response to the belief that clever high-tech sorting will have the capacity to create narrower fractions of materials then the economics will diminish, issues of cross-contamination will increase and the entire recycling sector will suffer.

Ultimately we are faced with two scenarios – over-sophisticated, costly technology that risks impairing recycling efficiency or changing packaging design to align colours with categories.
