HVTSE™ Dry-less Technology Offers Multi-resin Flexibility PTi continues to make major investments in its own organization and particularly the engineering division. People make products and projects successful. PTi is firm believer in this philosophy. Touting some of the industry’s leading engineers, PTi provides systems that feature advanced design innovations and technology developments.

HVTSE™ technology by Bandera

The patented HVTSE™ technology (High Vacuum Twin Screw Extrusion) employs a single atmospheric and dual high vacuum vent system coupled with a long L/D co-rotating twin screw extruder. This unique approach allows moisture (up to 12,000 ppm) and other volatiles to be removed as part of the extrusion process. In the case of recycled PET flake, the need for recrystallization is also eliminated. The energy savings realized from the elimination of the drying and crystallization steps is as high as 35% over conventional methods. The HVTSE™ technology is capable of processing PET, PS, PP, HDPE, ABS and other resins. Contact us today about scheduling a sheet extrusion process trial on our 2200 pph (1000 kg/hr) Demonstration Line using your own resins.

This is also true for flexible packaging in industrial sectors, such as construction materials, chemical products and animal feed.

To reach the 20% increased print speed, it is equipped with high-performance drive technology, as well as the new generation Turboclean inking and wash-up system.

EXTRUSION | PRINTING | CONVERTING

Dates back to 5000 BC. Popular as an aphrodisiac among the ancient Greeks. More than 5,000 varieties cherished by connoisseurs today. How else would you produce packaging film for something so treasured than on the best blown film line in the world?

Films for food packaging must meet the highest standards for shelf life, aroma barrier and product presentation. The VAREX blown film extrusion line enables the production of mono-layer, multi-layer and barrier films with excellent quality that has set the standard. Always consistent with up to eleven layers of exemplary sustainable production and safe, efficient handling. We'd be happy to tell you more about the exciting properties for your film extrusion process.

The researchers were inspired by printing ink, which crosslinks in a few seconds after exposure to UV light.

Maintaining efficiency Tests carried out by the Photovoltaik-Institut (PI) Berlin have shown that Tectosil, a thermoplastic encapsulant from Wacker, helps to maintain device efficiency. In particular, the silicone elastomer ensures that modules do not display leakage currents due to potential-induced degradation (PID) – which can occur in the event of higher voltages or penetrating moisture, and lead to significant performance losses in the solar module.

“We now have clear proof that Tectosil is capable of reliably suppressing PID effects in solar cells.” In addition, Evonik says it has developed a complete acrylic lens package, Plexiglas Solar Pre-Fab Optics, to provide access to Concentrated Photovoltaic (CPV) optics, while cutting the cost and lead times associated with tooling. The lens panels are part of the Plexiglas Solar (Acrylite Solar in the Americas) range, which consists of speciality PMMA moulding compounds and sheet products for solar applications. The lens panels are combined with a Secondary Optical Element (SOE) to create a complete optical train package for assembly directly into CPV modules. This allows customers to avoid buying a tooling device needed to create the product. “This allows us to deliver world-class performance to our customers while bypassing the tooling process, to save both time and money,” said Christopher Walby, new business development manager of Evonik’s Acrylic Polymers business line. “We are also offering the product in small quantities of as little as 10 panels to be

additive in compounds can contribute to sustainability by potentially cutting raw material use, lowering energy consumption and enabling product scrap recycling. Its low density compared to many other polymers allows the creation of lighter, thin wall products while maintaining product properties. Vistamaxx PBE can reduce compound processing temperatures for reduced energy use, it says. “When used in a polyolefin blend, it can contribute to less overall waste in the manufacturing process, as any scrap produced during processing can be recycled,” says the company. Vistamaxx PBE can be dry-blended – using existing equipment – with PP before processing. Vistamaxx PBE

The company’s product lines are not engineered as standard equipment, said Chew, but are designed for each customer. “We do not try to commoditise our customers’ applications,” he said. “We engineer machinery that is tailored to individual customer needs.”

On a roll At this year’s Chinaplas, Illig will introduce its RDM-K and RDK series of automatic of roll-fed thermoforming machines. The current third generation of RDM-K models are designed for high-volume cup production in a range of shapes and sizes. RDK series machines rely on roll-fed material to produce bowls, trays and hinged packs, such as those used on supermarket display shelves. At the show, an RDM 70K with 680 x 300mm forming surface will make close to 45,000 APET cups Gloucester

The new platform also claims higher efficiency, productivity and reliability, better quality rewind reels, lower noise levels and more effective, operator-friendly control systems. Atlas also makes the Titan range of secondary slitter rewinders for flexible packaging materials, plastic film, labelstock, laminates and paper. The latest Titan SR9 series modular slitter rewinders provide high levels of slitting productivity, design modularity and rewind reel quality, says Atlas. New features include reduced power consumption and faster set-up time. Maag Pump Systems will showcase its Extrex pump family, including the unveiling of the new EA pump that was developed specially for the Asian market. Extrex EA is a localised extrusion pump that covers most extrusion applications. Assembled at the company’s new facility in Shanghai, it integrates key components, such as gears and bearings made in Maag’s European facilities, to guarantee high standards of quality. The EA pump covers most standard extrusion applications, providing a differential pressure of up to 200 bar.
