An object of the present invention is to provide a film-shaped battery packaging material capable of curing an adhesive layer provided between a base layer and a barrier layer in a short time, thereby having excellent adhesion strength and excellent formability. In a battery packaging material including a laminate having at least a substrate layer, an adhesive layer, a barrier layer, and a sealant layer in this order, a reaction method comprising a thermosetting resin, and (A) a curing accelerator and an elastomer resin or (B) By forming the adhesive layer with a cured product of the resin composition of the resin beads, the adhesive layer provided between the base material layer and the barrier layer can be cured in a short time, and the preparation time for processing can be shortened. Furthermore, by providing the above-mentioned adhesive layer between the base material layer and the barrier layer, the adhesion strength between the base material layer and the barrier layer is high, and excellent moldability can also be obtained. |
