<p>PROBLEM TO BE SOLVED: To provide a film type packaging material for a cell, which can be made thin by disposing a coating layer as an outermost layer as a replacement for an adhesive layer and a substrate layer in a conventional film type packaging material for a cell, and which can reduce the lead time while achieving chemical resistance, molding property, and an interlayer adhesiveness between a barrier layer and a coating layer.SOLUTION: The packaging material for a cell comprises a laminate having at least a coating layer, a barrier layer, and a sealant layer in the stated order, in which the coating layer has at least three layers comprising a first coating layer, a second coating layer, and a third coating layer, disposed in such a manner that the first coating layer is positioned as the outermost layer and the third coating layer is positioned on the barrier layer side. The first coating layer, the second coating layer, and the third coating layer are each formed of a cured product of a resin composition containing a heat-curing resin and a curing accelerator to have sufficient specific hardness. Thereby, the packaging material can be made thin and is configured to have excellent chemical resistance, molding property, and interlayer adhesiveness between the barrier layer and the coating layer, to reduce the lead time, and to achieve efficient production.</p> |
