Abstract: A polyester film for use in a laminate with a metal plate comprises a polyester-group resin containing a white pigment having a mean particle diameter of 0.01 to 1.8 mu m at a content of 10 to 30% by weight. The film has (a) a void ratio of 4 to 30%, (b) a melting peak temperature of 150 to 245 DEG C , (c) an amount of oligomer of not more than 3% by weight and (d) an orientation degree of 0.7 to 4.0. When the film is laminated on a metal, it can provide excellent light interruptive, lamination, forming and processing properties.

Abstract: Disclosed is a metal-film laminate comprising 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 a 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", an 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.

Abstract: A metal-film laminate comprises a metal sheet and a biaxially oriented polyester film laminated on the metal plate. The degree of orientation of the film is controlled such that a film, having a thickness T and having a mean degree of orientation X in the region from a surface of the metal sheet to a position T/2 in the thickness direction of the film, has a degree of orientation at points within the region from the surface of the metal sheet to the position T/2 in the range of X +/-0.5X and a degree of orientation at the surface of the film remote from the metal sheet which is not less than 2X. The metal-film laminate can be processed by drawing etc., to provide cans for storage.
