  • White porous polyester film and preparation method thereof
    Patent number: 8999499
    Abstract: A white porous polyester film of the present invention comprising a polyester-based monopolymer/copolymer blend, a crystalline polymer resin which is not miscible with a polyester and has a heat deformation temperature of 90° C. or higher, inorganic particles, a whitening agent, and a stabilizing agent has improved optical properties, and thus is useful as a film for use in printing, labeling, electronics, and display applications.

  • WHITE, POROUS, SINGLE-LAYER POLYESTER FILM AND METHOD FOR PREPARING SAME
    Publication number: 20090042015
    Abstract: The present invention relates to a white, porous, single-layer polyester film comprising a polyester resin, particles of a noncrystalline polymer which has a heat deformation temperature higher than the temperature of the drawing process of said film by at least 10° C. and is not miscible with the polyester resin, inorganic particles and a whitening agent. The inventive single layer film has sufficient process stability as well as good optical properties, and thus is useful as a film for use in printing, labeling, electronics and display applications.
