  • Cold drawn high-orientation multilayered film and process for manufacture of said film
    Patent number: 4469753
    Abstract: A high-orientation multilayered film incorporates at least one cold drawn, highly oriented resin layer excellent in mechanical strength and suitable mainly for use as packaging material. Because of its specific stratal construction which is highly adaptable to afford a wide variety of specific functions, the composite film is suitable for manufacture of thermally shrinkable films which excel in transparency and in ability to shrink rapidly particularly at low temperatures. Also disclosed is a process for drawing at specific low temperatures at high expansion ratios the aforementioned multiplicity of resin layers either all by themselves or in conjunction with layers of other resins by utilizing the cold drawability of the aforementioned resin layers excelling in mechanical strength.
    Type: Grant
    Filed: December 8, 1983
    Date of Patent: September 4, 1984
    Assignee: Asahi-Dow Limited
    Inventors: Isao Yoshimura, Osamu Mizukami, Hideo Hata, Junichi Kageyama, Takashi Kaneko
