  • Film structure
    Patent number: 5972496
    Abstract: A film structure comprises a first sealable skin layer (a) of an olefin co- or terpolymer having an external surface which contains a slip/antiblock system. The slip/antiblock system comprises non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane and silica antiblock particles. Layer (a) is located on one side of a core olefinic polymer layer (b). On an opposite side of the core layer (b) there is a second skin layer (c) which is ethylene homopolymer and which is free of the slip/antiblock system, optionally the second skin layer (c) is metallized.
    Type: Grant
    Filed: April 28, 1997
    Date of Patent: October 26, 1999
    Assignee: Mobil Oil Corporation

  • Film structure
    Patent number: 5858552
    Abstract: A film structure comprises a first outer skin layer (a) of an olefin co- or terpolymer having an external surface which is sealable and machinable, the first skin layer containing a non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane, and which is located on one side of a core olefinic polymer layer (b) on an opposite side of the core layer there is a second skin layer (c) which is ethylene homopolymer and which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from about 1.25 to about 2.5.

  • Metallized film structure
    Patent number: 5753363
    Abstract: A metallized film structure comprises a first outer skin layer (a) of an olefin co- or terpolymer having an external surface which is sealable and machinable, the first skin layer containing a non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane, and which is located on one side of a core olefinic polymer layer (b), on an opposite side of the core layer there is a second outer skin layer (c) which is an ethylene homopolymer which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer having a metal deposited thereon. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from about 1.25 to about 2.5.
