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.

Abstract: This invention relates to a chlorine free, wax free aqueous composition for providing a repulpable water vapor barrier coating for flexible packaging applications. The composition includes a tackifier resin, a polymer and enough water to provide dispersions of the tackifier resin and the polymer. It may also include a filler with a plate like structure.

Abstract: The composition comprises a polymer emulsion containing, for example, polyvinylidene chloride having a particle size distribution finer than 10.mu., and an additive with generally the same size distribution, for example aluminum silicate, calcium carbonate, polyvinyl acetate polystyrene, polyacrylates, carboxylated styrene butadiene, or mixtures thereof in emulsion or powder form which is capable of interstitial combination with the polymer particles. The composition has a critical pH between about 2 and 9. The method of repulping coated packaging is also disclosed.
