Abstract
Abstract A laminated material comprises (A) a layer composed mainly of polyolefin, (B) a layer composed mainly of a saponified produce of an ethylenevinyl acetate copolymer, a polyamide resin or a polyester resin, (C) a vacuum deposited metallic layer, and (D) a layer composed mainly of a transparent thermoplastic resin. This laminated material has superior gas barrier properties, light-shielding properties, moisture resistance, etc. and is suitable for use as a packaging material.
