PROBLEM TO BE SOLVED: To provide a method for producing a battery packaging material molded body, by which ink is suitably printed on an outer surface even after having being stored over a long period and transported.SOLUTION: A method for producing a battery packaging material molded body 11 includes: a step of preparing a battery packaging material in which at least a base material layer 1, a metal layer 3, and a sealant layer 4 are laminated in order; a molding step of subjecting the battery packaging material to cold molding; and a surface modification step of subjecting an outer surface of the base material layer 1 of the battery packaging material to surface modification treatment before or after the molding step. In the method for producing a battery packaging material molded body 11, the surface modification treatment is corona treatment, only a part of the base material layer 1 outer surface being subjected to the surface modification treatment.SELECTED DRAWING: Figure 2 |
