  • Adhesive polymers for forming laminate structures
    Patent number: 9150763
    Abstract: Laminate structures comprising one or more sheets of material bonded together with an adhesive polymer. The adhesive polymer is a polyester amide, polyester urethane, or polyester urea.
    Type: Grant
    Filed: March 13, 2008
    Date of Patent: October 6, 2015
    Inventors: Leonardo C. Lopez, Alveda J. Williams, William J. Harris
  • Composite material and method of making the composite material
    Patent number: 8101283
    Abstract: A composite is formed by inserting a ceramic powder into a channel of a preform to form a ceramic powder filled preform. The ceramic powder has at least one reactive ceramic powder. The preform is a ceramic, ceramic-metal composite, metal or combination thereof that has walls that define a plurality of channels each channel having an opening at a surface of the preform. The ceramic powder filled preform is infiltrated with a molten metal to form the ceramic-metal body, which has at least one ceramic phase that is a reaction product of the reactive ceramic and molten infiltrated metal.
    Type: Grant

  • Polyolefin based peelable seals
    Patent number: 7863383
    Abstract: The invention relates to a polyolefin-based heat sealable and peelable seal. The peelable seals comprise from 5 to 98 percent by weight of a propylene based plastomer or elastomer and from 2 to 95 percent by weight of a second polymer selected from the group consisting of polyethylene, polybutylene, and styrenic polymer and mixtures thereof. The invention also relates to tamper evident peelable seals. The invention also relates to methods of making and using the heat sealable, peelable seal.
