摘要: [Problem] To provide: a resin-coated metallic plate which cannot undergo the occurrence of a retort brushing phenomenon (the formation of white spots) or the delamination of a film under retort sterilization treatment conditions; and others. [Solution] A resin-coated metallic plate having a resin layer (A) and a resin layer (B) is characterized in that the resin layer (A) contains 50 to 80 wt % of a polyethylene terephthalate-based resin (I) and 20 to 50 wt % of a polybutylene terephthalate-based resin (II), wherein the resin layer (B) contains 50 to 80 wt % of a polyethylene terephthalate-based resin (III) and 20 to 50 wt % of a polybutylene terephthalate-based resin (II), the polyethylene terephthalate-based resin (I) has a melting point of 210 to 230° C. inclusive, the polybutylene terephthalate-based resin (II) has a melting point of 215 to 225° C. inclusive, and the polyethylene terephthalate-based resin (III) has a melting point of higher than 230° C. and 205° C. or lower.

摘要: The disclosure relates to a can lid for food or drink, the can lid including an end and a tab for opening a score formed on the end. The end and/or the tab includes an aluminum alloy containing: Mn: 0.5 mass % to 1.4 mass %, Mg: 2.0 mass % to 4.5 mass %, Si: 0.6 mass % or less, Fe: 0.8 mass % or less, Cu: 0.25 mass % or less, Cr: 0.10 mass % or less, Zn: 0.25 mass % or less, and Ti: 0.10 mass % or less. With this configuration, even if the end and/or the tab contains a recycled aluminum alloy made up of aluminum UBCs as a raw material, a can lid having such an end and/or tab that has properties required for a can lid, such as pressure resisting strength, can be provided.
