PURPOSE:To manufacture resin coated steel plate for can end, easily openable end, drawn can, drawn and re-drawn can, drawn and re-drawn can with stretching, 5 gallon can excellent in processing adhesion. CONSTITUTION:Resin film having two-layered structure, in which the tack starting temperature of upper layer resin is set to be higher by 5 deg.C or more than that of lower layer resin and the melting point of the upper layer resin is set to be higher by 20-70 deg.C than the tack starting temperature of the lower layer resin, is used so as to be pressure-welded for the first time on one side or both the sides of steel plate, which is heated up to the temperature ranging from the tack starting temperature of the lower layer resin to the melting point of the upper layer resin. After that, the resin film is pressure-welded for the second time and forward on the steel plate, the temperature of which lies within the domain ranging from the tack starting temperature of the lower layer resin to that of the upper layer resin. |
