Zusammenfassung: | PURPOSE:To provide a manufacturing method by which an excellent decorative property can be imparted on the outer surface side of a can body part of a cylindrical metal can with bottom. CONSTITUTION:A cylindrical metal can body 1 with bottom is formed from a metal sheet. A can body part 2 is heated, and a polyester film 6 with a printed layer is heat-bonded by a thermosetting type adhesive layer. The adhesive is thermally set by heating the metal can body 1, and a metal can body 10 is obtained. A cylindrical metal can body with bottom is formed from a metal sheet. On a can body part 2, a polyester film with a printed layer is press- bonded by an electron beam setting type resin adhesive layer. An electron beam is cast, and the adhesive is set, and a metal can body is obtained. A thermosetting type paint 7 is coated on the can's internal surface side of the metal can body on which the film 6 is bonded, or a metal sheet, the side to become a can's internal surface of which is covered by a polyester film, is used. After the bonding of the film 6, a neck in process and flange process are applied. A thermosetting type overcoat layer is provided on the film 6. |
