PROBLEM TO BE SOLVED: To provide a film-shaped packaging material for batteries which allows a thinner film formation to be materialized by providing a coating layer as a top layer instead of an adhesion layer and a base material layer in a conventional film-shaped packaging material for batteries, and which is high in the film strength of the coating layer and superior in formability, and enables the shortening of a lead time.SOLUTION: A packaging material for batteries comprises a laminate having at least, a coating layer, a barrier layer, and sealant layer in this order. The coating layer is composed of a monolayer or multilayer formed by a hardened material of a resin composition including a thermosetting resin and a hardening accelerator. The resin composition used to form at least one layer of the coating layer is arranged to include reactive resin beads, which enables the rise in formability, and the shortening of a lead time. |
