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.
