Abstract

A process for production of polyester film of polyethylene terephthalate and copolymers thereof for packing of food products and drugs involves drying of polyester granulated material, melting thereof, preparation of amorphous half-finished product by the method of melt extrusion to the taker-in, biaxial separate orientation, heat fixing, cooling and winding the film to the roll. Prior to melting granulated material is subjected to thermal degassing at temperature of 180–2000 C and pressure of 0.075–0.150 N/mm2.
