Vacuum bags for food packaging made of high-barrier PA/PE film

For the production of bags we use smooth imported nine-layer film, which reliably protects the products to be packed from oxygen, nitrogen, carbon dioxide, water vapor, prevents the penetration of odors, frostbite, drying, has a special elasticity that allows freezing the contents.
The bags are used for packaging in a modified gas environment or vacuum depending on the properties of the product, they are used with professional vacuum cleaners.
New modern equipment allows to produce bags with veils, notches to facilitate the opening of the contents. Dimensions of bags, color, density of film layers can be agreed with the manager of the company if you wish to produce STM products.
All products comply with hygienic norms and standards of Ukraine.

Characteristics of the film are given in the table

Composition: PA/PE.
Color: TRANSPARENT.
