ABSTRACT:
A metal-film laminate including a metal plate and a biaxially oriented polyester-group film laminated on the metal plate. The orientation degree of the film is controlled such that, when the thickness of the film is represented by T and the mean orientation degree of the film in the area from the metal-plate side surface to a position of T/2 in the thickness direction of the film is represented by X, the orientation degree of the film in the area from the metal-plate side surface to the position of T/2 is in the range of X.+-.0.5X and an orientation degree of the film at the non-metal-plate side surface is not less than 2X. When the metal-film laminate is processed by drawing etc., an excellent drawing property and an excellent impact resistance of an obtained metal-film laminated product can be achieved.
