ABSTRACT:
A can that features superior resistance against puncture under higher puncture strength, and superior resistance against flange cracking. The resin-coated aluminum seamless can body of the present invention features superior resistance against cracks in the can wall during distribution, and resistance against flange cracking, wherein the inner and/or outer surface of the can of the aluminum seamless can10is coated with a layer of thermo-plastic resin, the thickness of the thermoplastic resin layers of the inner surface and the outer surface is a total of 2-50 μm, with a minimum thickness of the aluminum plate of the side wall of the can 0.110 mm or less, and the tensile stress at break measured for the aluminum plate that is removed from the thermo-plastic resin of the side wall of the can in the direction of the circumference of the can, is 450 MPa or less, the product of the minimum thickness of a plate of the side wall of the can including the thermo-plastic resin <t> (mm), and the tensile stress measured of the side wall of the can including the thermo-plastic resin in the direction of height of the cans (MPa), is <t ×s>≧30. The thermo-plastic resin layer is a thermo-plastic polyester resin layer having oriented crystals, wherein the heat of fusion of the polyester resin layer is not less than 15 J/g.
