METHOD FOR MANUFACTURING RESIN FILM COVERED METAL SHEET FOR DRAW REDRAWING CAN

摘要

PURPOSE: A method for manufacturing a resin film covered metal sheet for draw redrawing can is provided to manufacture a container having superior preserving property for contents of the container and beautiful external appearance by completely removing existing painting and printing processes from the draw redrawing can. CONSTITUTION: The method for manufacturing a resin film covered metal sheet for draw redrawing can comprises the steps of performing draw redrawing processing on the cross section of a resin film layer(3) consisting of one or more resin films selected from polyolefin, polypropylene, nylon and polyester; performing curved surface printing on the resin film in advance correspondingly to the shape of the can so that the printed curved surface is formed in a shape corresponding to the outer circumference of a can manufactured after draw redrawing process; forming an over-coating layer(1) by over-coating a transparent material such as varnish on the surface of a printing layer(2) that is curved surface printed after curved surface printing; and producing a laminated metal sheet by covering the resin film completed by passing through the above steps on a metal sheet(5).
