摘要： 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.

摘要： A battery packaging material 1 of this invention has a stretched heat-resistant resin film layer as an outer layer 2 which is laminated and integrated on one surface of an aluminum foil layer 4 through a first adhesive layer 5; and a non-stretched thermoplastic resin film layer which is laminated and integrated as an inner layer 3 on the other surface of the aluminum foil layer 4 through a second adhesive layer 6, in which the second adhesive layer 6 is an adhesive layer which is formed by a dry lamination method and whose melting point is 60° C. to 100° C., the adhesion strength of the inner layer 3 and the aluminum foil layer 4 is 3.0 N/15 mm width or more at 80° C., and the adhesion strength is 2.0 N/15 mm width or less at 120° C. The battery packaging material has good productivity, can suppress cost, and can secure sufficient seal properties, in which when the temperature of a battery case constituted by the packaging material excessively rises, degassing is performed, so that the burst of the packaging material due to the internal pressure rise can be prevented.

摘要： Provided is a molding packaging material which 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 2 as an outer layer, a heat fusible resin layer 3 as an inner layer, and a metal foil layer 4 arranged between the two layers. The heat fusible resin layer 3 is composed of a single layer or a multi-layer. The innermost layer of the heat fusible resin layer 3 is made of a resin composition containing a heat fusible resin, an anti-blocking agent, a slip agent, and a fluoropolymer-based lubricant.
