Who we are

MOLTENI S.R.L. is a company that was born in the 70s as a reality manufacturer of heat-shrinkable sheaths, gaskets, pipes and profiles in PVC, and wire ropes covered with plastic materials, specializing since the beginning in the supply of products on technical specifications and customized on customer needs.

The company philosophy has always been to pursue, as a primary goal the complete customer satisfaction, national and international, both in terms of services and quality and for interpersonal relationships, through direct contact between the customer and the technical part.

With this intent, aimed at continuous customer satisfaction, in 2017 the company implemented some lines for the production of tubular plastic nets for packaging, containment and protection.

Finally, in 2019, the company was purchased by a new owner who, after acquiring the company shares, added a further injection of enthusiasm, freshness and knowledge techniques in the field of plastic nets.

All this allows the company to present itself on the market today as a young, flexible reality with high technical knowledge in the field of extruded mesh.

Where we are?

Our new industrial settlement is located in northern Italy, in Sirtori (LC), in Via Del Peschierone 12, in the middle of the industrious Brianza. The company is located 40km from Milan, 35km from Bergamo and less than 15km from the main motorways of northern Italy.

We can count today on a settlement industrial area of 4,000 m2, consisting of Area Production, Logistics Area adjacent both internally and externally, Offices and large external space.

This new step represents a key choice for our growth and for the improvement of our customer service.

What we do?

We produce plastic nets starting from granules of various resins thermoplastics and formulations, depending on the request of the customer, from the characteristics that the market requires toour product or its application.

Some products from our range come subjected to particular processes, such as ironing longitudinal, the bi-orientation of the fibers plastics, cutting, welding and other types of conversions

How we do it?

Extrusion

The extrusion process takes place through the dissolution of the plastic granule, inside the extruder which forces, with its action, the melted plastic inside heads of developed internally and extrusion dies. The different choices in using different heads and dies determine the different nature of the products.

Orientation

The process of one- or two-way orientation is intended to orient the plastic fibers in order to obtain a more light but with significantly higher tensile strength and stiffness values. To do this, the plastic is stretched using machinery with elite technology.

Shelters - Plastic Netting Tree guards

Why do you need Shelters Tree guards?

Wildlife is integral to the life of fields. As they seek to satisfy their natural needs (food and reproduction), animals can cause damage to trees and shrubs. Farmers need to be well acquainted with the different types of guards in order to use them properly and make the right choice for protecting their trees.

One of the most important keys to success with newer ornamental trees and shade trees is to protect the bark of these young trees for the first 5 to 10 years after planting.

The bark of a tree is like an artery in our bodies. The living part of the bark carries sap filled with nutrients and life nurturing water from the roots to the leaves. Any damage to the bark of young trees is significant and a major hurdle for the tree to overcome since it reduces the flow of nutrients and water.

Never underestimate how important it is to protect the ark of younger trees.

Wildlife damage to trees

Roe and red deer, rabbits and hares damage trees in various ways. Damage may be related to feeding and/or behaviour and its appearance provides clues as to the species responsible.

Browsing: this refers to the removal and consumption of seedlings, buds, leaves or needles, vertical shoots orlateral branches. Animals usetheir teeth to detach the palatable parts of plants within their reach. Deer, rabbits and hares all cause this type of damage, as they seek to supplement their usual diet of herbaceous and semi-woody vegetation.

Bark gnawing: this type of damage is caused by rabbits and hares It is closely correlated with food scarcity and with the animals’ need to wear down their incisors. It consists of bark nibbling and is often characterised by oblique teeth marks at the collar or base of the trunk of young trees.

This damage mainly affects trees of less than 10 years old, and often leads to the death of the tree. The causes of rubbing are essentially behavioural. Male deer use tree trunks to rub off the velvet from their newly acquired antler growth when it starts to shed. During the rutting period, deer search for mates and engage in mock combat against young trees to release their aggression and also mark their territory with scent signals.

Which kind of tree guard device can we use?

On the market there are several ways of providing protection for individual young trees. It is useful to differentiate and made an anlysis between all the products. In particularly we can focus on the two different most used products:

TREE TUBE SHELTER and PLASTIC NETTING TREE SHELTERS

Why use our Plastic netting Tree Shelters?

Cheaper and more convenient

The most marketed tubes are nested in each other by five or more, sold rolled up and delivered in boxes.

Plastic Netting tree shelter guards are less bulky, and usually sold flat and pre-folded. This makes them easier for storage and carrying. The purchase price of mesh tree guards can be up to 35 % lower than tree TUBE shelters.

Unattractive to wasp nests

In the spring, the confined space created by the diameter of small tree shelters favours nesting of the wasps. With the summer, wasp activity and nest size increase. They proliferate and are made aggressive by the heat. During tree pruning, stings are frequent. The microclimate in tree guards is less favorable for wasps and it is rare to observe nests within them.

Easier for pruning

Low tree densities optimise initial growth by reducing competition from other trees, but induces the development of numerous defects in shape. Pruning is a means to correct these defects.

The diameter of the tree shelter is critical (≤ 12 cm) because it constrains branches. It can be difficult to insert pruning shears into a narrow tube when removing the unwanted branches. A mesh tree guard of 20 cm in diameter is the ideal device to facilitate the workof tree pruning.

Promote balanced tree growth

Plastic tree TUBE shelters can cause physiological modifications in the growth of young tree seedlings by creating a microclimate within the tube. The most visible effect is a substantial elongation of the annual leading shoot (sometimes 2 to 3 fold longer than that of unsheltered tree).

However, a reduction in root and stem diameter growth of the trunk has been also observed. While earlier studies focused on temperature and light modifications to explain the distorted growth of trees inside TREE TUBE shelters, more detailed studies have shown that ventilation is crucial. Without good ventilation, resulting from free convetion through the top of the shelter, the supply of CO2 to the tree is too low.

Shelters TUBE have been improved by creating chimney-effect ventilation with holes drilled at the bottom, resulting in unnatural trunk diameter growth. However, the shoot-root ratio remains unbalanced. This abnormal biomass allocation in ventilated tree TUBE shelters results from the lack of tree movement within the TUBE shelter. The movement of the tree stem induced by the wind influences the way in which material is allocated to different parts of the growing plant. Repeated swaying leads to a thickening of the lower stem and the rapid development of a structural root stem. This phenomenonis called thigmomorphogenesis. Finally we can say that a PLASTIC NETTING TREE SHELTER promote a more balanced tree growth as the plastic netting promote a more “NATURAL” plant environment, letting air and sun passing through the mesh.

Quality criteria

Height and diameter

Shelters - Plastic Netting Tree guards

The effectiveness of a mesh tree guard depends on its capacity to protect tree seedlings during their entireperiod of vulnerability. The minimum height of a tree guard must always be greater than the critical height of possible damage inflicted on trees by an animal.

The standard heights of tree guards are 50 cm for rabbits/buck, 60 cm for hares, 120 cm for roe deer, and 180 cm for red deer. In areas where deer populations are very dense, the attractiveness of newly planted trees often compels farmers to use higher, heavier, and more rigid tree guards. These should be 150 cm high for roe deer and 200 cm high for red deer, and supported by reinforced wooden stakes. The standard diameter of mesh tree guards will depend on the type of tree to be protected: 10 cm to 15 cm for poplar; 14 cm to 15 cm for hardwoods with strong apical dominance (e.g. cherry, ash, maple, red oak); 20 cm to 25 cm for hardwoods with strong lateral development and weak apical dominance (oak, beech, walnut) and 30 cm to 33 cm for conifers.

Weight and stifness

For protecting hardwoods from wildlife damage in agroforestry plantations, heavyweight (200/250g/m), mixed and reinforced mesh tree guards combine the advantages of wide (1-3 cm) and fine (2-3 mm) mesh: thicker horizontal and vertical plastic strands provide rigidity and greater tear resistance, while the fine mesh prevents shoots from growing through the sides. This reduces the risks of malformation and browsing of the main stems.

Four pre-formed folds make the mesh guard easy to open for plaing on the tree withoutinjuring the tip, and help to maintain an oval cross-section which ensures the tree can grow easily out of the top.
