Abstract: A film-shaped packaging material for a cell in which a coating layer is provided as the outermost layer instead of a substrate layer and an adhesive layer in a conventional film-shaped packaging material for a cell, thereby making it possible to produce a thinner film; wherein the packaging material is provided with exceptional moldability and insulation performance and enables lead time to be reduced. The packaging material is a laminate having at least a coating layer, a barrier layer, and a sealant layer in the stated order, the coating layer including a single- or multiple-layer configuration formed by a cured product of a resin composition containing a heat-curable resin and curing accelerator, the laminate having a piercing strength of at least 5 N, as measured in compliance with JIS 1707:1997, and the coating layer having a breakdown voltage of at least 1.0 kV, as measured in compliance with JIS C2110-1.

Abstract: A battery packaging material of a first aspect identifiable from the outside has exceptional moldability, insulating properties, and reduced external appearance defects and seal defects. A battery packaging material of the second aspect identifiable has post-molding concealment and adhesion properties, exceptional electrolyte resistance and surface insulating properties. The battery packaging material of the first aspect includes a laminate of at least a base material, adhesive, metal and sealant layers sequentially laminated, at least one of the base material and adhesive layers includes a dye. The battery packaging material of the second aspect includes a laminate of at least a decorative, base material, metal and sealant layers sequentially laminated; the decorative layer has at least a first and second decorative layers from the base material layer side. The decorative layer includes coloring and matting agents. The resin ratio is at least 60% by mass for the first and second decorative layers.
