[Problems] To provide a resin-coated metal sheet that exhibits excellent trimming property at the time of being formed into a seamless can, and is capable of providing a seamless can that closely adheres to the printing ink and exhibits excellent abrasion resistance. [Means for Solution] A resin-coated metal sheet including a metal sheet and a layer of a polyester resin which chiefly comprises an ethylene terephthalate unit formed on at least one surface of the metal sheet, wherein the polyester resin is a blend of a lowly crystalline polyester resin and a highly crystalline polyester resin.
A resin-coated metal sheet including a metal sheet and a layer of a polyester resin coating the metal sheet, the polyester resin chiefly comprising an ethylene terephthalate unit formed on at least one surface of the metal sheet, wherein said polyester resin is a blended polyester resin comprising a blend of a lowly crystalline polyester resin and a highly crystalline polyester resin, wherein said highly crystalline polyester resin is a homopolyethylene terephthalate or a polyethylene terephthalate containing isophthalic acid in an amount of not larger than 3 mol %, and said lowly crystalline polyester resin is a polyethylene terephthalate containing isophthalic acid in an amount of 12 to 18 mol %.
