Heat-shrinkable laminate film
 Disclosed herein is a heat-shrinkable laminate film excellent in gas-barrier property and oil-resistance and heat-sealing resistance, comprising a core layer of a gas-barrier resin which is a copolymer of vinylidene chloride or a copolymer of ethylene and vinyl alcohol, the outer layer (A) of a resin which is a copolymer (I) of ethylene and alpha-olefine having specific gravity of 0.900 to 0.950 and of a crystal melting point of 110.degree. to 130.degree. C. or a mixture of more than 20% by weight of the copolymer (I) and less than 80% by weight of a copolymer (II) of ethylene and vinyl acetate having crystal melting point of 80.degree. to 103.degree. C., the other outer layers (B) of a resin which is a cross-linked material formed from a polymer selected from the group consisting of the copolymer (I), the copolymer (II) and mixture of the copolymer (I) and the copolymer (II) by exposing the polymer to an ionizing irradiation, and two adhesive layers disposed between the core layer and the outer layers (A) and (B).
