Abstract: The present invention provides water-based coatings that provide liquid resistance when applied to various substrates. The coatings are particularly suitable for cellulosic substrates such as paper or paper board. In addition to liquid resistance, the coatings have good heat sealability, and are resistant to roll blocking. Preferably, the coatings are recyclable and/or repulpable with the substrates to which they are applied. The coating compositions comprise one or more polymer binders, and one or more particles. Preferably, at least one polymer binder has a glass transition temperature (Tg) less than 10° C. Preferably, at least one polymer binder has a heat seal onset temperature of less than 200° C. Preferably, at least one particle has a mean particle size greater than 4 μm. It is also preferable that the particles have a melting point greater than 60° C.

The fire-resistant paper comprises Kraft paper with a preferred eight of 40 to 60 pounds/3,000 ft2, and a fire-resistant ink applied to each side of the Kraft paper. The fire-resistant ink includes an acrylic resin, a dispersant, and a boron compound, and optionally, talc and a molybdate compound. When heated, the fire-resistant ink preferably converts the Kraft paper into a non-combustible and heat shielding substance.

Abstract: Coating compositions are disclosed that can be applied to at least a food-facing surface of a molded fiber container to make the coated container suitable for applications involving long term storage of a dry or frozen food item combined with short term contact with the food item in a liquid or moist state. The coating compositions include carboxylated polyvinyl alcohol copolymer and a crosslinking resin that is epichlorohydrin-based and/or azetidinium-functionalized. The compositions can also include clay particles or other suitable fillers. After crosslinking and drying, the compositions form a thermoset barrier coating in which the polyvinyl alcohol is bonded to the crosslinker by a plurality of function groups including ester functional groups.
