An object of the present invention is to provide a film-shaped battery packaging material, which can replace the adhesive layer and the base material layer in the conventional film-shaped battery packaging material and provide a coating layer as the outermost surface layer, Thereby, thinning is realized, and the film-shaped battery packaging material has chemical resistance, moldability, and interlayer adhesion between the barrier layer and the coating layer, and can shorten the production cycle. In a battery packaging material including a laminate having at least a coating layer, a barrier layer, and a sealing layer in this order, the coating layer has at least three first coating layers, second coating layers, and third coating layers layer, the first coating layer is located on the outermost surface layer, the third coating layer is arranged on the side of the barrier layer, and the first coating layer is formed with a cured product of a resin composition containing a thermosetting resin and a curing accelerator, respectively , the second coating layer and the third coating layer, and making it meet a specific hardness, it can be thinned, and it is excellent in chemical resistance, moldability, and interlayer adhesion between the barrier layer and the coating layer, In addition, it is possible to shorten the production cycle and efficiently manufacture. |
