Abstract
A resin laminate structure comprising a layer of a polymer selected from the group consisting of polyolefins and saponified products of ethylene-vinyl acetate copolymers and a layer of a blend comprising (A) a polyolefin and (B) a saponified product of an ethylene-vinyl acetate copolymer having an ethylene content of 25 to 50 mole % and a degree of saponification of at least 96% at an A:B mixing weight ratio ranging from 98:2 to 2:98, said two layers being laminated so that they are adjacent to each other.
