ABSTRACT:
This invention comprises an impact-resisting glazing structure having a support frame and a multilayered composite secured in the frame wherein the composite comprises two sheets of glass spaced apart by an interior spacer positioned along the periphery of the glass sheets with a polyester film adhered to the interior surface of one of the glass sheets. The polyester film has an asymmetric orientation of crystals and molecules in the amorphous regions and having an in-plane distribution of crystalline and amorphous phases in which the (100) planes of said crystals lie in the film plane and wherein in the film, said crystals have chain axes oriented toward the transverse direction such that dominant physical properties are obtained in the transverse direction.
