Metal-polyesterfilm laminate

摘要

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.
