Abstract
Disclosed herein is a heat-shrinkable multi-layered laminate film comprising a core layer made of a saponified copolymer of ethylene and vinyl acetate, two outer layers made of a mixture of a copolymer of ethylene and vinyl acetate having a crystal melting point of 85.degree. to 103.degree. C. and a copolymer of propylene and ethylene having a crystal melting point of 126.degree. to 155.degree. C. or a linear low-density polyethylene having a crystal melting point of 110.degree. to 125.degree. C. and two adhesive layers disposed between the core layer and the two outer layers, the multi-layered laminate film being excellent in gas-barrier property, oil resistance and peel-resistance of the sealed parts in the heat shrinkage and suitable for heat-shrinking packaging of foodstuffs, particularly for vacuum heat-packaging of foodstuffs.
