  • Plastic material for packaging
    Patent number: 5919863
    Abstract: The instant composition is a sealable and peelable polymer composition consisting essentially of a first ethylene copolymer grafted with a vinyl monomer and a second ethylene copolymer selected from ethylene/methylacrylate copolymers, ethylene/ethylacrylate copolymers and ethylene/butylacrylate copolymers.
    Type: Grant
    Filed: December 24, 1996
    Date of Patent: July 6, 1999
    Assignee: Borealis A/S
    Inventors: Hanneli Seppanen, Markku Sainio, Torvald Vestberg, Lars-.ANG.ke Mattsson
  • Laminate and production method thereof
    Patent number: 5700586
    Abstract: The invention concerns laminates incorporating plastic layers and cellulose fiber layers and a method for the production thereof. The plastic layers and the cellulose fiber layers incorporated in the laminates can be separated intact from each other in aqueous defibering by virtue of a water-soluble polymer layer placed adjacent to the fibrous layer whereby all components of the laminate become recyclable for reuse. The laminates can be produced using extrusion coating/laminating methods. The laminates according to the invention are suited to use as, e.g., wrapper and packaging materials.
    Type: Grant

    Date of Patent: December 23, 1997
    Assignee: Borealis Polymers Oy
    Inventors: Erkki Laiho, Markku Sainio
  • Plastic material for packaging
    Patent number: 5677069
    Abstract: The invention relates to sealable and peelable polymer composition which comprises 5-35 weight-% styrene modified ethylene copolymer and 95-65 weight-% ethylene butyl acrylate copolymer. Ethylene copolymer is preferably ethylene butylacrylate copolymer (E/BA) or ethylene vinyl acetate copolymer (E/VA).
    Type: Grant
    Filed: May 12, 1995
    Date of Patent: October 14, 1997
    Assignee: Borealis Holding A/S
    Inventors: Hanneli Seppanen, Torvald Vestberg, Markku Sainio, Lars-.ANG.ke Mattsson
  • Plastic material for packaging
    Patent number: 5663232
    Abstract: The invention relates to sealable and pealable polymer compositions which contain 20-80 weight % polyolefin and 80-20 weight % ethylene-hyaroxyacrylate co- or terpolymer in which as one comonomer is 5-30 weight % hydroxyacrylate and as another comonomer 0-40 weight % vinyl compound. The composition is pealable also after heat processing.
