A method of making a removable closure for use in sealing a food or beverage container, the method comprising: (a) providing a metal-containing substrate; (b) providing a coating composition, said coating composition incorporating ingredients comprising: (i) at least one polycyclic polyester resin, wherein the polycyclic polyester resin comprises first and second fused rings that share at least one atom in common; and (ii) crosslinkable, resole phenolic resins with the proviso that at least one of such resole phenolic resins is a crosslinkable, alkylated resole phenolic resin; and wherein the coating composition is substantially free of resins and resin precursors comprising covalent halogen-containing functionality, and wherein the coating composition is substantially free of resins and resin precursors incorporating bisphenol A; (c) applying the coating composition onto at least a portion of a surface of the substrate under conditions effective to provide a dried coating having an average dry film weight of 1 to 25 grams per square meter of coated surface area; (d) at least partially curing the applied coating composition to form a coating on the substrate; (e) forming the coated substrate into a removable closure comprising the coating on an interior surface of the closure; and (f) providing a gasket to at least a portion of the coating on the interior surface of the closure. (a) providing a metal-containing substrate; (b) providing a coating composition, said coating composition incorporating ingredients comprising: (i) at least one polycyclic polyester resin, wherein the polycyclic polyester resin comprises first and second fused rings that share at least one atom in common; and (ii) crosslinkable, resole phenolic resins with the proviso that at least one of such resole phenolic resins is a crosslinkable, alkylated resole phenolic resin; and wherein the coating composition is substantially free of resins and resin precursors comprising covalent halogen-containing functionality, and wherein the coating composition is substantially free of resins and resin precursors incorporating bisphenol A; (i) at least one polycyclic polyester resin, wherein the polycyclic polyester resin comprises first and second fused rings that share at least one atom in common; and (ii) crosslinkable, resole phenolic resins with the proviso that at least one of such resole phenolic resins is a crosslinkable, alkylated resole phenolic resin; and wherein the coating composition is substantially free of resins and resin precursors comprising covalent halogen-containing functionality, and wherein the coating composition is substantially free of resins and resin precursors incorporating bisphenol A; (c) applying the coating composition onto at least a portion of a surface of the substrate under conditions effective to provide a dried coating having an average dry film weight of 1 to 25 grams per square meter of coated surface area; (d) at least partially curing the applied coating composition to form a coating on the substrate; (e) forming the coated substrate into a removable closure comprising the coating on an interior surface of the closure; and (f) providing a gasket to at least a portion of the coating on the interior surface of the closure.
