Abstract: A packaging material for a power storage device includes a heat resistant resin layer 2 as an outer layer, a sealant layer 3 as an inner layer, and a metal foil layer 4 arranged between these layers. The sealant layer 3 is composed of one layer or a plurality of layers. The innermost layer 7 of the sealant layer contains a random copolymer containing propylene as a copolymerization component and another copolymerization component other than propylene, a roughening material, and a lubricant. The roughening material is composed of particles containing a thermoplastic resin. The center line average roughness Ra of the surface 7a of the innermost layer 7 is 0.05 μm to 1 μm. It can provide a packaging material for a power storage device which is excellent in formability and hard to generate white powder on the surface.

Abstract: A molding packaging material is capable of ensuring good slipperiness to secure good formability when molding the molding packaging material and is less likely to cause white powder on a surface of the packaging material. The molding packaging material includes a substrate layer as an outer layer, a heat fusible resin layer as an inner layer, and a metal foil layer arranged between the two layers. The heat fusible resin layer is composed of a single layer or a multi-layer. The innermost layer of the heat fusible resin layer is made of a resin composition containing a heat fusible resin, an anti-blocking agent, a slip agent, and a fluoropolymer-based lubricant.
