摘要：
The present invention relates to a resin film laminated metal sheet for can, in which both faces of the metal sheet have resin film laminated layers, and a surface free energy γs of a face of the resin film is 10 dyn/cm or more to less than 30 dyn/cm, the face becoming an inside of can after can-making and being contacted with stuffed food contents. As the resin film, applicable is a polypropylene film or a propylene ethylene based random copolymer film of polypropylene being a main component. Further, a resin film of polyester being a main component and containing a wax component of 0.1 to 20% is used in a resin film to be an inside of can after can-making. The resin film laminated metal sheet for can according to the invention has excellent formability and adhesion while can-making and superior taking-out property of stuffed food contents.
