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 sealant film has a structure made of a laminated body of two or more layers. The laminated body includes a first resin layer 7 containing 50 mass % or more of a random copolymer containing propylene and a copolymer component other than propylene as copolymer components, and a second resin layer 8 formed by a mixed resin containing a first elastomer-modified olefin based resin having a melting point of 155° C. or higher and a crystal melting energy of 50 J/g or more, and a second elastomer-modified olefin based resin having a melting point is 135° C. or higher and a crystal melting energy of 30 J/g or less. With this structure, when the inner pressure of a power storage device is excessively increased, breakage (separation) occurs inside the sealant layer, causing gas-releasing, which in turn can prevent bursting of the packaging material due to the inner pressure increase.

The heat-resistant resin layer 2 is made of a heat-resistant resin film having a hot water shrinkage rate of 1.5% to 12% and the heat-resistant resin layer 2 and the metal foil layer 4 are adhered via an outer side adhesive layer 5. The adhesive layer 5 is formed by an urethane adhesive agent containing a polyol, a polyfunctional isocyanate compound, and an aliphatic compound containing a plurality of functional groups capable of reacting with an isocyanate group in one molecule. With this, a packaging material can be provided in which excellent formability can be secured and delamination can be sufficiently suppressed without causing pinholes, etc., even when deep depth drawing is performed.
