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°to 103°C. and a copolymer of propylene and ethylene having a crystal melting point of 126°to 155°C. or a linear low-density polyethylene having a crystal melting point of 110°to 125°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.

A heat-shrinkable laminate film excellent in gas-barrier property, oil-resistance and peel-resistance, comprising a core layer made of a saponified copolymer of ethylene and vinyl acetate, two outer layers made of a resin selected from mixtures of 80 to 30% by weight of a copolymer of ethylene and v

A heat-shrinkable laminate film excellent in gas-barrier property, oil-resistance and peel-resistance, comprising a core layer made of a saponified copolymer of ethylene and vinyl acetate, two outer layers made of a resin selected from mixtures of 80 to 30% by weight of a copolymer of ethylene and vinyl acetate having a crystal melting point in a range of 85°to 103°C. and 20 to 70% by weight of a linear low-density polyethylene having a crystal melting point in a range of 110°to 125°C. or a copolymer of propylene and ethylene having a crystal melting point of 126°to 155°C., and two adhesive layers disposed between the core layer and the outer layers, the ratio of the weight of the copolymer of ethylene and vinyl acetate to the total weight of the polymers of the two outer layers being larger than 0.4.
