Inner surface corrosion resistance and outer surface printing excellent in the drawn and ironed cans for steel plate, can body and method of manufacturing the same

摘要

PROBLEM TO BE SOLVED: To provide a steel sheet for squeezing and drawing cans excellent in inner surface corrosion resistance and outer surface printability, a squeezing can, and its production method.;SOLUTION: In the steel sheet for the squeezing and drawing cans having thermoplastic resin film layers on both surfaces, a Ni-plated layer is laminated on the surface of the steel sheet, on its surface, a polyester resin film of 8-50 μm thickness is laminated on a surface corresponding to the inner surface side of a can of the Ni-plated steel sheet having a chromate membrane layer comprising metallic Cr and hydrated oxidized Cr 0.2-30 mg/m² in metallic Cr reduced quantity, and the polyester film of thickness 8-25 μm is laminated on a surface corresponding to the outer surface side of the can through an adhesion primer layer containing 20-70 mass% of a white pigment and/or a colored pigment. In the polyester resin film laminated steel sheet for the squeezing and drawing cans excellent in inner surface corrosion resistance and outer surface printability, the density of the polyester resin film to be the outer surface side of the can is 1.360 g/cm³ or below. The squeezing can of the polyester resin film laminated steel sheet for the squeezing can and its production method are also disclosed.;COPYRIGHT: (C)2006,JPO&NCIPI
