WIPO Patent Application WO/2021/006024

A1

This resin film laminate metal sheet is provided with a metal sheet and thermoplastic resin films fused onto both surfaces of the metal sheet, wherein the metal sheet is a steel sheet having a thickness of 0.08 mm or more or an aluminum sheet having a thickness of 0.15 mm or more. When a surface, of the thermoplastic resin film, opposed to a surface fused to the metal sheet is defined as a first surface, the surface tension of the first surface of at least one of the thermoplastic resin films is 50 mN/m or less, the surface tension of the surface fused to the metal sheet is 36 mN/m or more, and the amount of wax deposited to the first surface is more than 0 mg/m2 but not more than 5.00 mg/m2.
