Draw-ironed aluminum can and method of producing the same
[Problems] To provide an aluminum seamless can very excellent in stab resistance, corrosion resistance and productivity by using a resin-coated aluminum sheet. [Means for Solution] 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.
1. 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%.
