  • White, biaxially oriented polyester film with cycloolefin copolymer and process for producing the film
    Patent number: 6719940
    Abstract: A method of controlling the gloss of a white biaxially oriented polyester film. The film will include at least one layer containing a cycloolefin copolymer at a concentration of about 4 to about 60% by weight of that layer. The method includes the step of stretching the film in a machine direction to a ratio of about 2.3 to about 3.4 to obtain desired gloss characteristics.
