  • Polyester film containing minute glass spheres and fumed silica useful microfilm
    Patent number: 5278205
    Abstract: The present invention relates to films or sheets of linear polyester containing glass spheres having a certain particle size distribution and in a certain amount based upon the weight of the polyester film. The addition of the glass spheres improves several properties of the film, including the dynamic coefficient of friction. Preferably, a second film additive, fumed silica, of a controlled particle size distribution and weight is additionally added to the film. The addition of the fumed silica additionally improves several properties of the polyester film, including the static coefficient of friction of the film.
