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.

Abstract: Provided is a molding packaging material capable of sealing without causing sealing failure, significantly reducing cleaning frequency of a seal bar to improve productivity, and preventing occurrence of delamination. The molding packaging material includes a PBT terephthalate (PBT) layer 2, a heat fusible resin layer 3, and a metal foil layer 4 between the two layers. The PBT layer 2 and the metal foil layer 4 are bonded via an outer adhesive layer 5. The outer adhesive layer 5 is formed of a urethane adhesive cured film composed of a polyester polyol, a polyfunctional isocyanate compound, and polyhydric alcohol. The polyester polyol contains a dicarboxylic acid component, the dicarboxylic acid component includes an aromatic dicarboxylic acid. The dicarboxylic acid component contains an aromatic dicarboxylic acid. The content rate of the aromatic dicarboxylic acid in the dicarboxylic acid component is 40 mol % to 80 mol %. The Young's modulus of the cured film of the urethane adhesive is 70 MPa to 400 MPa. The PBT layer has tensile strength of 100 MPa to 300 MPa.

Abstract: An outer packaging material for a battery includes a heat resistant stretched resin film layer as an outer layer integrally laminated on one of surfaces of an aluminum foil layer via a first adhesive layer. A thermoplastic unstretched resin film layer as an inner layer is integrally laminated on the other surface of the aluminum foil layer via a second adhesive layer. An adhesive strength between the inner layer and the aluminum foil layer is 4N/15 mm-width to 30N/15 mm-width, and an adhesive strength between the outer layer and the aluminum foil layer is 2N/15 mm-width to 14N/15 mm-width. As a thermoplastic unstretched resin film constituting the inner layer, a thermoplastic unstretched resin film having a sealing strength of two sheets of the thermoplastic unstretched resin films arranged one on the other and heat sealed exceeding 30N/15 mm-width but not exceeding 110N/15 mm-width is used.
