Film provides crush protection, prevents penetration of dampness, protects against scratches, creates presentable appearance for packing product, possess flexibility, make it possible to manufacture bags at individual sizes. Also applies as covering material for pools, hothouses and as insulation material in construction field.

PE - PE – Polyethylene film (LDPE, LLDPE, LDPE/LLDPE, HDPE)

   Protects against oxygen and dampness. Used as disposable packing of short shelf life products in food industry, retail trades, “fast food”, also in agriculture sector and construction field. Being in direct contact with the product, it provides longer storage of products, helps to preserve their properties, prevents rapid drying, protects against external impact and off-odor permeation.

PE Coex – Co-extruded polyethylene film

   Co-extruded three-layer polyethylene film (different combinations of LDPE and HDPE are possible). Such film is distinguishes by improved optical properties. Also significantly increases tensile at break, stretching and puncture. Three-layer structure allows to achieve optimal technological and exploitation properties of film at cost minimization.

PVC – polyvinylchloride (PVC) film

   «Breathing film» used as disposable packing of long shelf life products. PVC film has all advantages of polyethylene films, but with improved capability. In line with all this, such films have “barrier-layer” effect, in other words transmission of air components (steam, carbon dioxide) outside and oxygen inside. As a result of such property secures a “breath” of products – maintenance of microclimate inside the package and thus long-term conservation of products.

BOPP – biaxially oriented polypropylene film
