Abstract: Disclosed is a polyester film for use of a laminate with a metal plate comprising 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 .degree.C , (c) an amount of oligomer of not more than 35 by weight and (d) an orientation degree of 0.7 to 4.0. When the film is laminated on a metal, it can indicate excellent light interruptive property, lamination property, forming property and processing property.

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.

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: Molten polyester sheet (2) is solidified by cooling it on the surface of a mobile cooling medium on which water film (7) is formed, and the sheet is stretched at least 4.5-fold in overall stretching ratio in a longitudinal direction through a plurality of stretching steps. Since casting is conducted via the water film, water is absorbed in the surface layer and the interior of the cast sheet, thus facilitating orientation by stretching in the longitudinal direction and lowering the stretching temperature. As a result, stretching with a high stretching ratio can be attained by multi-stage stretching without conducting high-temperature stretching. Thus, this process can accelerate film formation, improve productivity, and provide a film having reduced unevenness in thickness, less surface roughness and excellent abrasion resistance.
