Abstract
A pigmented, printable, biaxially oriented polymer film, also known as a synthetic paper, having one or more layers, is produced by (1) extruding a melt of a mixture made from crystallizable film-forming polymers, pigments or fillers, (2) allowing the extruded melt with pigments and fillers embedded in it to harden while controlling the temperature and thickness of the primary film produced followed by biaxial orientation and cooling. During this process, the temperature of the primary film is controlled in a range between its solidifying point and the temperature required for orientation such that the primary film is never cooled to a temperature below that required for orientation. Also the interval between solidification and orientation process is selected to allow crystallization of the film-forming polymer between the embedded particles of filler and pigment before orientation.
