1. An inside spray food or beverage container coating composition comprising:
an aqueous carrier; and
an emulsion-polymerized latex copolymer dispersed in the aqueous carrier, wherein the monomers used to produce the emulsion-polymerized latex copolymer (i) include one or more polymerizable surfactants and (ii) are substantially free of BPA, PVC, halogenated monomers, and styrene;
wherein the coating composition has an average viscosity ranging from about 5 seconds to about 40 seconds, pursuant to the Viscosity Test;
wherein the coating composition has a resin solids content ranging from about 10% by weight to about 30% by weight, based on a total weight of the coating composition; and
wherein the coating composition, when cured, has a glass transition temperature of 50° C. or greater.
