Abstract
A method for forming a heat sealable coating on a substrate, wherein the substrate is formed from at least one oriented polymer is shown. The method includes depositing an aqueous polymer dispersion on the substrate, wherein the aqueous polymer dispersion includes (A) at least one thermoplastic resin; (B) at least one dispersing agent; and (C) water; wherein the dispersion has a pH of less than 12, and drying the dispersion to form a first layer.
Claims11
