Abstract

An object of the present invention is to provide an organic-resin-coated metal sheet for beverages and foods having retort blushing resistance and can manufacturability, a manufacturing method thereof, and a metal can and a can lid that are made by processing the organic-resin-coated metal sheet. An organic-resin-coated metal sheet of the present invention is an organic-resin-coated metal sheet in which an unstretched film is stacked on at least a single surface of a metal sheet, and is characterized in that the unstretched film is composed of a polyester-based resin composition obtained by blending copolymerized polyester (I) composed mainly of a polyethylene terephthalate-based resin with crystalline polyester (II) composed mainly of a polybutylene terephthalate-based resin with a mixing amount of the crystalline polyester (II) of 20 to 45 wt %.
