  • Biodegradable paperboard laminate structure
    Patent number: 5213858
    Abstract: The present invention relates to a biodegradable paperboard-based package for various food products. The package utilizes a novel heat-sealable laminate structure wherein the exterior gloss heat-sealable layer is a degradable polymeric resin material such as a polyvinyl alcohol resin or a starch based low density polyethylene polymer resin. Utilization of the material in a novel fashion accelerates the paperboard substrate's degradative properties and tendencies.
    Type: Grant

  • Paperboard laminates having polar copolymer/nonpolar polymer blend surface coatings
    Patent number: 5196269
    Abstract: The present invention relates to a novel coextrusion coating for paper or paperboard substrates. The coextrusion includes a nonpolar polymer layer and a thin exterior skin layer made up of a nonpolar polymer and a polar copolymer. The addition of the polar polymer improves long term treatment level retention which improves long term wettability for printing and gluing adhesion during package or carton formation.

  • Non-foil composite structures for packaging juice
    Patent number: 4802943
    Abstract: The present invention relates to a non-foil composite barrier for an improved container for citrus juices and other liquids. The container utilizes a paperboard barrier laminate for the containment of essential oils and the prevention of losses of vitamin C. Also disclosed is a process of making the laminate. The laminate makes use of an inner barrier layer of a heat-sealable ethylene vinyl alcohol copolymer to enhance the barrier properties of the laminate.
