A molding packaging material excellent in interlaminar lamination strength is provided, in which it is possible to prevent deterioration of the interlaminar strength due to influences of electrolytes and also possible to prevent deterioration of the interlaminar strength due to influences of heat generation and/or expansion/contraction of the packaging material caused by repetition of charging/discharging. The molding packaging material of the present invention includes a heat resistant resin layeras an outer layer, a polypropylene layeras an inner layer, a metal foil layerarranged between the heat resistant resin layer and the polypropylene layer, wherein at least an inner side surface of the metal foil layeris subjected to a chemical conversion treatment, and the polypropylene layeris laminated on the chemical conversion treatment surface of the metal foil layer via an adhesive layer, wherein the adhesive layeris formed by applying an adhesive to the chemical conversion treatment surface of the inner side surface of the metal foil layer, the adhesive containing at least an organic solvent, a polyolefin resin having a carboxyl group in which the organic solvent is dissolved and an MFR measured at 130&#xb0; C. is 5 g/10 min to 42 g/10 min, and a multifunctional isocyanate compound.

Molding packaging material and method for producing same

Provided is a molding packaging material that can have an increased use life, can suppress a decrease over time in inter-layer lamination strength, and has superior molding properties in extrusion molding, draw forming, and the like. The laminate molding packaging material contains: an outside substrate layer () comprising a heat-resistant resin; an inside sealant layer () comprising a thermoplastic resin; and a metal foil provided between the two layers as a barrier layer (). In the heat-resistant resin of the outside substrate layer (), a biaxially oriented polyethyleneterephthalate film is used that, when the tensile breaking strength in the M direction is MB and the tensile breaking strength in the T direction is TB, the following are satisfied:500 MPa==700 MPa; and&#x2003;&#x2003;formula (I)||=30 MPa.&#x2003;&#x2003;formula (II)

Molding packaging material and battery case

Provided is a molding packaging material that can have an increased use life, can suppress a decrease over time in inter-layer lamination strength, and can have superior molding properties in extrusion molding, draw forming, and the like. The laminate molding packaging material contains: an outside substrate layer () comprising a heat resistant resin; an inside sealant layer () comprising a thermoplastic resin; and a metal foil provided between the two layers as a barrier layer (). A matte coat layer () comprising a heat resistant resin coating film containing a dispersion of inorganic or organic solid microparticles is formed on the outer surface of the outside substrate layer (), and the gloss value of the surface thereof is suppressed to no greater than 30%.

A molding packaging materialof this invention contains a biaxially stretched polyamide film layeras an outer layer, a thermoplastic resin layeras an inner layer, and a metal foil layerdisposed between the both layersand, in which a biaxially stretched polyamide film in which when the fracture strength of the film is defined as 'X' and the fracture strain of the film is defined as 'Y', the X/Y value is 230 MPa to 360 MPa is used as the biaxially stretched polyamide film. The molding packaging material can secure excellent moldability even when the molding packaging material is not coated with a slipperiness imparting component.

Molding packaging material and molded case

The molding packaging materialaccording to the present invention includes a heat resistant resin layeras an outer layer, a thermoplastic resin layeras an inner layer, a metal foil layerarranged between the heat resistant resin layer and the thermoplastic resin layer, and a black ink layerarranged between the metal foil layerand the heat resistant resin layer. The black ink layercontains carbon black, diamine, polyol, and hardening agent. The black ink layer does not partially crack and detach even when the molding packaging material according to the present invention is used in a somewhat harsh environment such as a hot and humid environment and/or at the time of molding or sealing.
