Abstract:
A laminated metal sheet for a two-piece can includes: a metal sheet; and first and second polyester resin layers formed on outer and inner face sides of the container, respectively. The first polyester resin layer contains polyethylene terephthalate or a copolymerized polyethylene terephthalate with a content of a copolymerized component of less than 6 mol % in a ratio of 30% to 60% by mass, polybutylene terephthalate or a copolymerized polybutylene terephthalate with a content of a copolymerized component of less than 5 mol % in a ratio of 40% to 70% by mass, and a polyolefinic wax in an amount of 0.01% to 3.0% in outer percentage, the second polyester resin layer is a copolymerized polyethylene terephthalate with a content of a copolymerized component of less than 22 mol %, and residual degrees of orientation of the first and the second polyester resin layers are less than 30%.
