Abstract: The present invention relates to a method comprising the steps of applying to a paper or paperboard substrate an aqueous dispersion of polymer particles which comprise structural units of a vinyl ester, vinyl alcohol, and an acrylate monomer, then drying the composition. The method provides a coating that has oil and grease resistance, mineral oil barrier performance, and beat scalability.

Abstract: The present invention relates to an article comprising a paper or paperboard substrate superposed with a film having a dry coat weight in the range of from 1 g/m2 to 20 g/m2; wherein the film comprising a copolymer which comprises structural units of a vinyl ester, vinyl alcohol, and an acrylate monomer. The coating provides oil and grease resistance, mineral oil barrier performance, and heat sealability.
