<p>PURPOSE: To provide a polymer coated metal laminate of superior compatibility of molding properties, particularly resistance to impact and taste characteristics by coating a layer, in which polyester A composed of ethylene terephthalate or ethylene isophthalate of specified melting point as main component and thermoplastic elastomer are blended together by a specified weight ratio, with extruded laminate. CONSTITUTION: A polymer coated metal laminate is formed by coating a layer I constituted of polyester A composed of ethylene terephthalate of ethylene isophthalate having melting point of 140-245 deg.C as main component and thermoplastic elastomer blended together by the ratio of 70:30-98:2 by the weight ratio. Resistance to impact is good even when a number of heat histories such as heat treatment in the can manufacturing process, retort treatment after the can manufacturing process and the like are applied after extrusion laminating to the metal and mold, and molding and can manufacturing are carried out by mixing thermoplastic elastomer of adequate amount i0 polyester having specified melting point. Not only the compatibility of resistance to impact with taste characteristics but also resistance to impact can be improved to a large extent by the above-said effect.</p> |
