  • Microwave energy interactive insulating structure
    Patent number: 9073689
    Abstract: A microwave energy interactive structure for heating, browning, and/or crisping a food item in a microwave oven includes a plurality of layers including a layer of microwave energy interactive material and a substantially continuous tie layer. The tie layer includes a thermoplastic material. Upon sufficient exposure to microwave energy, the tie layer softens and allows the adjacent layers to separate from one another to define a void between the respective layers.
    Type: Grant
    Filed: February 15, 2008
    Date of Patent: July 7, 2015
    Assignee: Graphic Packaging International, Inc.
    Inventors: John Cameron Files, Scott W. Middleton
  • Thermally activatable microwave interactive materials
    Patent number: 7868274

  • Anti-blocking coatings for PVdc-coated substrates
    Patent number: 7416767
    Abstract: A barrier composite having reduced blocking is disclosed. The composite may include a substrate, a barrier layer formed from polyvinylidene chloride disposed on the substrate, and an anti-blocking layer disposed on the barrier layer. The anti-blocking layer may be formed from polyvinyl alcohol, and optionally, colloidal silica, wax, or a combination thereof. Alternatively, the anti-blocking layer may be formed from a polymeric carrier material, colloidal silica, and a wax. Methods for forming such composites and for forming a roll of such composites are also disclosed.
