Beschreibung
Zusammenfassung:	The present invention provides water-based polymeric coatings, which are free of styrene, have enhanced bio-based content, excellent water resistance, grease resistances, and are heat sealable. The coatings are highly suitable for surface treatment of cellulose-based substrates and finished products made therefrom, for example disposable drinking cups. La présente invention concerne des revêtements polymères à base d'eau, qui sont exempts de styrène, ont une teneur biologique améliorée, une résistance à l'eau et des résistances à la graisse excellentes, et sont thermoscellables. Les revêtements sont hautement appropriés pour le traitement de surface de substrats à base de cellulose et des produits finis fabriqués à partir de ceux-ci, par exemple des gobelets à boire jetables.
