Abstract: A resin-coated aluminum alloy sheet which has a chromium-free surface treatment layer and has a coating film formed by applying an organic resin, and which exhibits excellent adhesiveness and excellent corrosion resistance even after being subject to severe forming such as drawing is provided. A resin-coated aluminum alloy sheet includes: an aluminum substrate having a surface treatment film on at least one surface thereof; and an organic resin film layer formed on the surface of the aluminum substrate. The surface treatment film includes 2 mg/m2 to 100 mg/m2 of zirconium in terms of metal atoms and at least any one of a polyitaconic acid, monosaccharide alcohol and disaccharide alcohol as an aluminum-ion-trapping agent.

Abstract: An easy open end comprising a resin-coated metal plate obtained by coating a metal substrate with a polyester film via a primer, wherein the primer comprises an epoxy resin or a polyester resin and a resole-type phenol resin, and the resole-type phenol resin has 0.2 to 2.0 methylol groups per a benzene ring. The end can be lightly opened without causing defect at the time of opening the end by pushing in the end of a tab and cutting the score and, particularly, can be excellently opened at high temperatures without arousing the problem even in a state of being heated at high temperatures featuring excellent corrosion resistance, resistance against the content and retort resistance.

Abstract: The present invention provides a resin coated seamless aluminum can and a resin coated aluminum can lid having adhesiveness and corrosion resistance by applying a non-chromium chemical conversion coated film to an aluminum alloy sheet and by applying an organic resin layer to the non-chromium chemical conversion coated film. For this end, an organic-inorganic composite surface treated layer containing 2 to 20 mg/m2 of zirconium compound expressed in terms of zirconium atoms, 1 to 10 mg/m2 of phosphorus compound expressed in terms of phosphorus atoms, and 5 to 60 mg/m2 of organic compound expressed in terms of carbon atoms is formed on at least one-side surface of an aluminum alloy sheet, and an organic resin coated layer is formed on the organic-inorganic composite surface treated layer.

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 can 10 is 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 ?m, with a minimum thickness of the aluminum plate of the side wall of the can 0.

Abstract: A surface-treated tin-plated steel sheet for welded cans forming a surface-treating layer comprising chiefly a silane coupling agent on the surface of a tin-plated layer formed on the surface of a steel sheet, wherein the amount of free tin (Sn) (X g/m2) in the tin-plated layer and the amount of silicon (Si) (Y mg/m2) in the surface-treating layer lie in ranges satisfying all of the following formulas, 0.2?X?13, Y?1.0, Y?1.58X+6.92 and Y??0.36X+10.70. Despite of a non-chromium surface treatment, the surface-treated tin-plated steel sheet features excellent weldability, particularly high-speed weldability, close adhesion during the working and excellent corrosion resistance.
