The invention relates to the food industry, in particular, to the production of multilayer polymer films, which are used for packing of foodstuffs, in particular, meat and products of its processing, fish and products of its processing, and also for preparing the tubular shells for packing of sausage articles and packets for packing and prolonged storage of foodstuffs under vacuum conditions. A sandwich film for packing of foodstuffs includes the first layer, which contains polyamide (PA), the second layer, which contains adhesive agent (AD), the third layer, which is barrier for Oand contains copolymer of ethylene and of vinyl alcohol (EVOH), the fourth layer, which contains polyamide (PA), the fifth layer, which contains adhesive agent (AD), the sixth layer, which contains polyolefin (PE), moreover as polyamide the layers contain terpolymer of polyamide 6/6,6/12 with melting point (Tm), at least, and with the temperature of crystallization (Tc) of , or its mixture with polyamide or with copolyamide. |
