Polyolefin film (POF) is used in food and other industries as packaging material. This is a well-known transparent food casing, in which bakery products, meat and fish products, semi-finished products, toys, cosmetics and much more are wrapped.

What it is?

The POF film contains copolymers of ethylene with alpha-olefin and ethylene with vinyl acetate. And also there is a barrier layer. The film is harmless, which allows it to come into contact with any type of food . It is in it that food is packed on the shelves of grocery stores. POF film preserves perishable foodstuffs well, protects them from damage during transportation.

Polyolefin film consists of several (3-5) layers . This multi-layer gives it a gas-tight ability, and the unique molecular structure of the cross-crossed type provides high strength - for example, a POF film with a thickness of 15 microns is equal in strength to a PVC film with a thickness of 20 microns. The polyolefin casing is able to withstand high temperature and mechanical stress.

Since each layer is created separately, their defective features do not match. When they are stacked on top of each other, the strength of the film increases.

A characteristic feature of the material is the fact that the structure of the POF film is closer to fabrics than to polymers. We will also list its other features.

• Profitability . The same rollers with POF and PVC films have different lengths, since they have different thickness indicators. This means that a video with POF film will be a more profitable purchase - it has a greater length. In addition, when working with polyolefin material, you can save on electricity, since its lower density allows you to lower the temperature in the heat tunnel.
• Strength . As already mentioned, this type of shell, due to its structure, has greater strength than other competing materials. It resists tears, punctures, impacts and sprains equally well.
• Environmental friendliness . The composition of the PVC film has a negative ability to emit toxic chlorine during operation. The POF film is odorless, does not emit harmful substances, and has hypoallergenic properties.
• Temperature Range . The shrinkable POF film does not lose its properties at temperatures from –50 to + 30 ° С. TU-film at a temperature of 120 ° C provides a shrinkage rate of up to 120 seconds and reaches 64%. If shrinkage occurs in the region of 80%, then the effect of "second skin" appears, which allows packing objects of complex geometric shapes.
• POF film ensures complete tightness of the package .

The material is resistant to solvents, fats, and foreign odors.

Where is it used?

The scope of application of the POF film is quite extensive

• Food packaging - sausages, meat and fish cuts, semi-finished products, containers with meat and fish preparations. Packaging of products with a tendency to absorb foreign odors such as tea, coffee, chocolate and others. The film does not allow such delicate delicacy as cheese of all types to deteriorate. Fruits, vegetables, herbs are wrapped in it.
• The film keeps the freshness of baked goods for a long time - freshly baked bread, packed in a POF-shell, retains all its qualities and aroma. The micro-perforated surface of the packaging material allows the product to breathe and protects it from hardening.
• The durability and strength of the material allows it to be used in such aggressive environments as marinades and brines . Therefore, containers with pickled cheeses, pickles, barbecue and fish marinades are covered with foil.
• POF film is used for packing stationery, magazines, wallpaper, books, paper products of any kind ., disposable sets of dishes, toys, household and household items, car parts and much more.
• In large industries with the help of such a film, manufactured products of textile or other quality are packed.
• Stable technical characteristics create conditions for printing . This film is used to create colorful labels for bottles with drinks and yoghurts.
• Polyolefin film can replace corrugated board , polyethylene of increased thickness and other similar materials. The scope of application is so huge that it is impossible to list everything.

The same equipment is suitable for working with POF film as with other shrinkable types.

Forms of issue

The manufacturer manufactures products in 2 types

• Half-sleeve - the material has a cut along one of the folds; when it is unfolded, a covering sheet is obtained. Used for wrapping trays, boxes, pallets and other items.
• Sleeve . Used for shrink wrapping - the item is placed inside the film, after which the edges are cut, sealed and heat shrinkable.

Manufacturers and their products

Polyolefin packaging material has been known on the market for a long time, but Russian manufacturers began to produce it in 2005. Until that time, it was started from abroad. For the first time, the company "ProfUpak" was engaged in the introduction of POF films on the domestic market. These products are in great demand and popularity among consumers.

The assortment of the company:

• half sleeve 13 microns, 1000 m, 150 mm;
