A polyester-resin-coated seamless can including a reduced diameter portion obtained by neck processing within a distance of 0% to 15% from a can body uppermost portion with respect to a total height of the can from the can body uppermost portion to a can bottom of the can. A ratio Im/Iu is 1.0 or more, where Iu (cps/μm) is calculated by dividing a maximum peak intensity in a range satisfying 15°≤2θ≤19° of an outer-surface coating in a maximum reduced diameter portion of the reduced diameter portion by a thickness of the coating at the measurement site, and Im (cps/μm) is calculated by dividing a maximum peak intensity in a range satisfying 15°≤2θ≤19° of outer-surface coating at a measurement site within a distance of 45% to 60% from the can body uppermost portion by a thickness of the outer-surface coating at the measurement site.

Polyester-resin-coated seamless can and method for manufacturing the same

To provide a bath for surface treatment capable of forming a surface-treating film having excellent corrosion resistance by a high-speed electrolytic treatment, and a method of producing a surface-treated steel plate having excellent corrosion resistance and closely adhering property to the coating maintaining good productivity. A bath for surface treatment used for forming a surface-treating film on the surface of a steel plate by cathodic electrolysis, the bath for surface treatment containing Zr and/or Ti, and a polycarboxylic acid.

Bath for surface treatment, method of producing surface-treated steel plate by using the bath for surface treatment, and surface treated steel plate produced by the same method

A seamless can including a resin-coated steel plate. The can is a draw-ironed steel can having a resin coating formed on at least the inner surface of the can, wherein the resin coating on the inner surface of the can has a tensile strength of 160 to 360 MPa. Also disclosed is a method of producing the draw-ironed steel can.

Draw-ironed steel can and method of producing the same

A surface-treated steel plate obtained by forming, on at least one surface of the steel plate by cathodic electrolysis, a surface-treating film which contains a mixed oxide of an oxide of Fe and at least one of an oxide of Zr or an oxide of Ti, and a polycarboxylic acid, the amount of Zr or Ti, or the total amount of Zr and Ti if both of them are present, being from 3 to 300 mg/mand the amount of C being from 0.1 to 5.0 mg/m.

[Problems] To provide a resin-coated metal sheet that exhibits excellent trimming property at the time of being formed into a seamless can, and is capable of providing a seamless can that closely adheres to the printing ink and exhibits excellent abrasion resistance. [Means for Solution] A resin-coated metal sheet including a metal sheet and a layer of a polyester resin which chiefly comprises an ethylene terephthalate unit formed on at least one surface of the metal sheet, wherein the polyester resin is a blend of a lowly crystalline polyester resin and a highly crystalline polyester resin.

Resin-coated metal sheet and seamless can made therefrom

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 canis 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 &#x3bc;m, 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 &#x3c;t&#x3e; (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 &#x3c;t &#xd7;s&#x3e;&#x2267;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.
