Laminate sheet and process for making a seamless can using the same

摘要

A laminate for can-making is disclosed, comprising a metal sheet (2) and a thermoplastic resin layer provided on the surface of the metal sheet. The thermoplastic resin layer comprises a laminate film layer (3; 5, 6, 7) comprising a polyester-base resin intermediate layer (A) containing 10 wt% or more of coloring agent particles, a polyester-base resin outer surface layer (B) and a polyester-base resin backing layer (C). The outer surface layer (B) and the backing layer (C) each contains the coloring agent particles in an amount of 20 wt% or less and at the same time, in an amount less than that contained in the intermediate layer (A). Also disclosed is a process for making a can using the laminate.
