ABSTRACT:
A resin laminate include: a gas barrier resin layer (layer A) made of a saponified ethylene-vinyl acetate copolymer or a polyamide resin; a layer (layer B) made of at least one type of thermoplastic resin selected from a group consisting of a polycarbonate resin, a chlorine containing resin, a thermoplastic polyester resin, an acrylic resin and a styrene resin; and an adhesive polymer layer (layer C) for bonding the gas barrier resin layer (layer A) and the layer (layer B). The adhesive polymer layer (C) is a polymer composition consisting essentially of modified polyolefin grafted with unsaturated carboxylic acid or unsaturated carboxylic anhydride and modified ethylene-vinyl acetate copolymer obtained by grafting vinyl acetate on ethylene-vinyl acetate copolymer.
