(57) [Summary] (Modified) [Problem] Good corrosion resistance with no dissolution of exogenous endocrine disrupting chemicals into the contents of food cans and discoloration such as black sulfide discoloration. In addition, we provide cans with beautiful printed appearance. SOLUTION: In a drawn can (including a deep drawn can) obtained by a single drawing process or a plurality of drawing processes by press-forming a metal plate, a metal surface on the inner surface side of the can (A) has an adhesive portion. There is a layer and a thermoplastic polyester resin film layer (B), and the adhesive layer has a number average molecular weight (Mn) of 6000 copolymerized in a weight ratio of epoxy resin to polyester resin of 95: 5 to 5:95. 〜30000 epoxy-polyester copolymer resin, including a curing agent, From the metal plate coated with (A) and (B), the final can body is formed into a range of 1.5 to 2.5 as a drawing ratio, and is formed into a thermoplastic polyester resin film layer by the forming process. A film-laminated squeezed can characterized in that the entered distortion is released. |
