Laminate film having a heat-shrinkage rate greater than 15 percent at 90.degree. C.
 Described is a laminate film excellent in oil-resistance, heat-resistant sealing ability, peel resistance and gas-barriering property having a percentage of heat-shrinkage of larger than 15% at 90.degree. C. comprising a center layer consisting of a copolymer(I) of vinylidene chloride and both two outermost layers consisting of a mixture of 20 to 70% by weight of a copolymer(II) of ethylene and alpha-olefin of density of 0.900 to 0.950 and of crystalline melting point of 110.degree. to 125.degree. C. and 80 to 30% by weight of a copolymer(III) of ethylene and vinyl acetate with the proviso that the content of the copolymer(II) in the total amount of copolymers in both the two outermost layers is less than 65% by weight and showing a structure of having an adhesive layer between the center layer and the outermost layer.
