  • Patent number: 8741366
    Abstract: A treated paper product is provided according to the invention. The treated paper product comprises a result of applying a water based emulsion to a paper base sheet to provide an impregnated paper product, and drying the impregnated paper product to a water content of less than about 8 wt. % to provide the treated paper product. The water based emulsion includes a barrier and/or release forming component comprising at least one of stearylated melamine, polyethylene wax, paraffin wax, isoparaffin wax, microcrystalline wax, fluoropolymer wax, silicone wax, alkyl ketene materials, octyl succinic anhydride, Werner chrome complex, natural wax, and mixtures thereof. The water based emulsion can have a solids content of between about 2 wt. % and about 50 wt. % when it is applied to the paper base sheet. Methods for manufacturing and using the treated paper product, and a combination food and treated paper product are provided.
    Type: Grant

  • Patent number: 8067087
    Abstract: A heat seal adhesive paper product is provided according to the invention. The heat seal adhesive paper product comprises a paper substrate and a heat activatable adhesive. The heat activatable adhesive comprises a result of applying an aqueous polymer dispersion to the paper substrate to form a coated paper substrate and drying the coated paper substrate. The aqueous polymer dispersion includes a polymer component having a melting temperature (Tm) greater than about 220° F. and a glass transition temperature (Tg) greater than about 50° F. A method for manufacturing a heat seal adhesive paper product is provided and a laminate product containing the heat seal adhesive paper product is provided.
