PURPOSE:To manufacture easily a packaging vessel which is excellent in its corrosion resistance and appearance characteristic by drawing a laminated body formed by sticking a specified organic resin covering material to both faces of a steel foil by an adhesive agent. CONSTITUTION:Both faces of a steel foil 2 having 100kg/mm<2>>=sigmaB>=30kg/mm<2> tensile strength sigmaB, 120mum>=T>=15mum thickness T, and a surface treating film containing Sn, Cr, Ni, etc. on the surface are covered with thermoplastic resins 4, 6 of polyolefin, polyamide, polyester, polycarbonate, vinyl chloride resin, vinyldene chloride resin, high nitrile resin and others, by polyurethane adhesive agents 3, 5. A laminated body 1 which consists of this steel foil 2 and the organic resin covering materials 4, 6, and whose whole thickness (t) is shown by an inequality (1) is manufactured. By drawing it by a punch 11 and a die 12 by using a wrinkle holder 10, a side face seamless composite vessel which is excellent in its corrosion resistance and appearance characteristic, and has no wrinkle can be manufactured. |
