Abstract
A resin laminate structure comprising a layer of a polyolefin and a layer of an ethylene-vinyl acetate copolymer saponified product having an ethylene content of 25 to 50 mole % and a degree of saponification of at least 96 %, wherein a thermoplastic polymer having a carbonyl group in the main chain or side chain thereof is incorporated in at least one of said two layers in an amount of 5 to 100 parts by weight per 100 parts by weight of said polyolefin or said ethylene-vinyl acetate copolymer saponified product.
