The disclosed laminate includes a layer of a saponified copolymer of ethylene and vinyl acetate thermally bonded directly (without use of an adhesive) to a layer of thermoplastic with a high interlayer adhesive strength therebetween. The laminate is produced by pretreating the surface of the thermoplastic layer to be bonded with a low temperature plasma and then thermally bonding the two layers together.
