  • Patent number: 10968288
    Abstract: A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes an emulsion-polymerized latex copolymer having copolymer chains of one or more ethylenically-unsaturated monomers and one or more styrene offset monomers. Preferably, the coating composition is substantially free of BPA, PVC, and styrene. The method may also include curing the sprayed coating composition, thereby providing the coating on the interior surface of the food or beverage container.
