Patent ID: 8647729

Claim:
A draw-ironed aluminum can having a resin coating on at least the inner surface of the can, wherein the coating resin on the inner surface of the can has a tensile strength of 270 to 420 MPa, said resin coating on the inner surface of the can is of a two-layer constitution comprising a surface layer of a highly crystalline polyester resin and a lower layer of a lowly crystalline polyester resin, and a thickness ratio of the surface layer and the lower layer is 1:5 to 9:1, and said highly crystalline polyester resin is an ethylene terephthalate type polyester resin containing a copolymer of isophthalic acid in an amount of not less than 0 mol% but less than 3 mol%, and the lowly crystalline polyester resin is an ethylene terephthalate type polyester resin containing the copolymer of isophthalic acid in an amount of 10 to 18 mol%.
