[Problem] The purpose of the present invention is to provide a film-like packaging material for batteries, which is capable of providing excellent adhesion strength by curing an adhesive layer in a short time, said adhesive layer being arranged between a base layer and a barrier layer, and which has excellent formability. [Solution] A packaging material for batteries, which is formed of a laminate that sequentially comprises a base layer, an adhesive layer, a barrier layer and a sealant layer in this order. By having the adhesive layer formed of a cured product of a resin composition that contains a thermosetting resin and (A) a curing accelerator and an elastomer resin or (B) reactive resin beads, the adhesive layer arranged between the base layer and the barrier layer can be cured in a short time, thereby reducing the lead time. In addition, by providing the adhesive layer between the base layer and the barrier layer, the adhesion strength between the base layer and the barrier layer is increased and excellent formability can be achieved. |
