Traditionally, the food can manufacturing industry has been using lacquer coated steel sheets. However, there is a move to regulate the use of lacquer coated steel sheets in the EU due to the discovery that bisphenol contained in the lacquer paint is an endocrine disrupter. Under these circumstances it was desirable to develop new types of laminated steel sheet. These new laminated steel sheets would not contain endocrine disrupters, but would have properties comparable to, or better than conventional lacquer coated steel sheets, and would be easy to form, enable laminated film to firmly adhere to the substrate steel sheet, be corrosion resistant, and easily release their contents. The new product also had to be compatible with existing can manufacturing facilities. NKK responded to such requirements and developed and marketed a world-first film laminated steel sheet for food cans that satisfied the requirements as can-making steel sheets, including the content release property.
