FIELD: laminated thermoshrinkage film. SUBSTANCE: the film has a central layer consisting of copolymer of ethylene and vinyl alcohol, two external layers of mixed of vinyl-acetate and ethylene- alpha-olefinic copolymers, and two adhesion layers. The film features a free shrinkage of at least 40%, preferably, at least 45%, and most preferably - at least 50% in both directions at a temperature of 120 C, and maximum shrinkage force in the lateral direction within the entire range of the shrinkage temperatures not exceeding 0.5 N/cm. The film is designed for parking of deformable products, such as trays. EFFECT: enhanced tightness of packing. 14 cl, 2 tbl |
