  • Heat-setting process for polyester film
    Patent number: 4042569
    Abstract: Improvement in a two-stage heat-setting process for asymmetrically, biaxially oriented polyester film wherein the film from the second heat-setting stage is heat set a third time and quenched. The starting film can be oriented by a transverse direction-machine direction sequence of drawing or a machine direction-transverse direction-machine direction sequence. The film can be machine direction drawn again after the second heat-set stage and relaxed an equal amount after the third heat-set stage. The film has improved dimensional stability in the transverse direction without a substantial loss in tensile strength at 5% elongation in the machine direction.
