Abstract:
A resin-coated metal sheet for containers that has excellent content releasability is provided. The resin-coated metal sheet includes a resin layer (A) and a resin layer (B). The resin layer (A) has a multilayer structure and is disposed on a side which, after the metal sheet is formed into a container, becomes the inner side of the container. The resin layer (B) is disposed on a side that becomes the outer side of the container. The resin layer (A) contains polyester as a main component and includes an uppermost resin layer (a1). A Raman band intensity ratio (I2968/I3085) on the surface of the resin layer (a1) is 0.6 to 0.9. The resin layer (B) includes polyester (I) composed mainly of polyethylene terephthalate and a polyester (II) composed mainly of polybutylene terephthalate. A Raman band intensity ratio on the surface of the resin layer (B) is 0.8 to 1.0.
