  • High barrier multilayer film
    Patent number: 6458470
    Abstract: The present invention is a high barrier multilayer film particularly suitable for packaging. The high barrier multilayer film is a film including (a) a core substrate layer having an isotactic polypropylene produced from Ziegler-Natta catalysts, and (b) an adjacent layer on at least one surface of the core substrate layer, wherein the adjacent layer (b) comprises an isotactic polypropylene produced from metallocene catalysts; or the high barrier multilayer film includes (a′) a core substrate layer having an isotactic polypropylene produced from metallocene catalysts, and (b′) an adjacent layer on at east one surface of the core substrate layer, wherein the adjacent layer (b′) comprises an isotactic polypropylene produced from Ziegler-Natta catalysts.

  • Opaque oriented polypropylene film
    Patent number: 6048608
    Abstract: The present invention relates to an opaque, biaxially oriented polymeric film having a thermoplastic polymer matrix material within which is located a stratum of voids. The voids are formed during orientation by a cavitating agent which is a particle of a cyclic olefinic copolymer. The solid particle is phase-distinct and incompatible with the matrix material.
