PROBLEM TO BE SOLVED: To obtain a can having a beautiful image on it, by electrostatically attracting color to one side of a long continuous film, which has a clear coat layer formed on its other side, by an electrophotographic printing method, by putting a layer of adhesive onto their uppermost layer, then by temporarily fixing them, and by heat-bonding the obtained printed film to the surface of a can body. SOLUTION: After a cylindrical can 1 is formed from a metal plate, a thermoplastic resin film 2 having a printing layer is heat-bonded, via a layer of adhesive, to the can body of the can 1 heated by an induction heater 28, thereby producing a film-laminate can. In the case, by means of development units 12-15 and by an electrophotographic printing method, several kinds of color toners are electrostatically attracted to one side of the long continuous thermoplastic resin film 2, drawn from a roll 6, which has a clear coat layer formed on its other side in advance. Subsequently, by means of a development unit 16, a layer of adhesive is put onto the uppermost layer of the color toners, thereafter they are temporarily fixed by an infrared oven 21. After that, the film 2 is cut and heat-bonded to the surface of the can body as a printed film for one can. |
