Metal can using polyester film laminated ECCS (electrolytic chromium/chromium oxide-coated steel)

Abstract

TULC™ (Toyo Ultimate Can) is a 2-piece press formed can using thermoplastic film laminated ECCS. It is required for the laminate to have excellent formability and strong adhesive strength to withstand the severe forming of the can body. In this paper, development of ECCS, polyester film and lamination technologies are described. By using the developed material, dry forming 2-piece can manufacturing system was accomplished and the following merits can be obtained; the metal can with high corrosion resistance and excellent flavor retention, and elimination of the can manufacturing energy, elimination of CO2 generation and solid waste generation of the can manufacturing process.
