摘要：

A triple layered thermoplastic resin laminated metal sheet for a can stock having excellent flavor retention of packed foods and drinks, excellent formability, excellent adhesion of the thus laminated resin layer to a metal sheet and excellent denting resistance, particularly excellent denting resistance at a low temperature, which comprises formation of a triple layered thermoplastic resin layer wherein a polycarbonate resin layer is sandwiched between polyester resin outer and inner layers on one or both sides of a metal sheet covered with a single layer of hydrated chromium oxide or a double layer consisting of an upper layer of hydrated chromium oxide and a lower layer of metallic chromium by using conventional film laminating, extrusion coating or the combination of these techniques.
