INDUSTRIAL APPLICABILITY The present invention uses a resin-coated steel sheet having a resin coating composed of a polyester resin film having a general-purpose composition with excellent economical efficiency, the adhesion of the resin coating is significantly improved, and the excellent corrosion resistance (impact resistance and barrier property) is obtained. And a method for manufacturing the same. The present invention, at least the inner surface of the can is coated with a biaxially stretched polyester film, the outer surface of the can is painted and/or printed resin-coated steel sheet is drawn or drawn/re-drawn. In the resin-coated steel can, the degree of crystallinity of the biaxially stretched polyester film on the side wall of the can inner surface is 42 to 52%, and the shrinkage amount of the biaxially stretched polyester film on the side wall of the can inner side is from 23°C to 5%. The shrinkage amount in the can height direction when the temperature is raised to 130° C. at a heating rate of C/min is less than 10% of the can height. |
