To provide a composite-layered polyester film laminated metal sheet for a container capable of preventing the contamination of a laminating roll caused by not only the wax added to a polyester film but also the oligomer or the like remaining in the film and having both of excellent meat releasability and DRD plate working properties, and its manufacturing method.
The composite-layered polyester film laminated metal sheet for the container is constituted by laminating a surface layer based on a polyester resin with a melting point of 245°C or above and an under layer based on a polyester resin, of which the melting point is lower than that of the surface layer, at least on one side of a metal sheet. The surface layer contains 0.01-2.0 mass% of polyethylene wax and the number average molecular weight Mn of the polyester resin of the surface layer after lamination is 1.4×104 or above.
