| description | A resin-coated metal sheet according to the invention of the present application that can suppress occurrence of retort blushing (white spots) includes a metal sheet, and a resin layer A coated on at least one side of the metal sheet. The resin layer A contains a polyester resin as a principal component, and the polyester resin is a blend of 30 to 50 wt % of a polyester I having a melting point of 210° C. to 256° C. and 50 to 70 wt % of a polyester II having a melting point of 215° C. to 225° C. The resin layer A has, in X-ray diffraction thereof, a peak intensity ratio satisfying the following formulas (1) and (2): (I100)II/(I100)I≥1.5 . . . (1) and (I100)II/(I011)II |
