Abstract: The invention relates to a composition which, when mixed with a polymer composition, allows for the formation of a continuous and cohesive film. The film is characterized in that it provides water, grease and oil resistance, provides a water vapor barrier and can used as wax replacement treatment and a top coat for flexible packaging, but also on other substrates. This film is formed at a very fast set speed without the need of thermal energy. The composition contains i) a salt of one or more of myristic, palmitic and stearic acid; and preferably also ii) a C9-C18 fatty acid complex of a metal ion, the metal ion having an oxidation state of at least 3. The invention also provides processes and coated substrates.

Abstract: A coating composition for the linerboard of corrugated paperboard provides water and grease resistance but is water vapor permeable, and thus permits a different mode of manufacture of corrugated paperboard when aqueous adhesives are employed in the assembly of the linerboards and corrugated medium; in particular the linerboards may be coated with the coating composition prior to assembly of the corrugated paperboard because the water vapor permeable coating permits escape of the water of the aqueous adhesive, during drying of the assembled components of the corrugated paperboard; the coating composition employs a styrene-acrylate copolymer and a C14-C18 fatty acid complex of a metal ion having an oxidation state of at least 3, such as chromium.
