<p>PROBLEM TO BE SOLVED: To prevent a resin film stuck on the surface of a can body with the aid of an adhesive layer from being released therefrom even when a can is subjected to retort treatment after an opening portion of the can body is diametrally narrowed in a precise manner in case of the necking-in of such a film-stuck can made of a metal, whose can body and can bottom are integrally formed, as to have a printed resin film stuck on the outer surface of the can body. SOLUTION: In such a film-stuck can made of a metal, whose can body and can bottom are integrally formed, as to have a printed resin film stuck on the outer surface of the can body, an organic/inorganic composite formation processing film which has 1 to 7 mg/m2 as an adhesion amount of phosphorus (P) and 5 to 50 mg/m2 as an amount of film carbon (C) and in which the ratio (C/P) of the amount of film carbon to the adhesion amount of the phosphorus is 2 to 10, is formed in advance on a metallic surface of the can, on which a resin film is stuck. A diameter of an opening portion at the top end of the can body is diametrally narrowed so as to be in the range of 79-87% with respect to the diameter of the can body.</p> |
