    Abstract: A heat exchanger includes a bag-like outer packaging material. A heat medium flows into an inside of the outer packaging material via the heat medium inlet, passes through the inside, and flows out of the outer packaging material via the heat medium outlet. An inner core material is arranged in the inside of the outer packaging material. The outer packaging material has an outer packaging laminate material including a metal heat transfer layer and a resin thermal fusion layer on a surface side of the heat transfer layer. The outer packaging laminate materials form a bag shape by integrally joining the thermal fusion layers along the peripheral edge portions. The inner core material includes the inner core laminate material with a metal heat transfer layer and resin thermal fusion layers on surface sides of the heat transfer layer. The thermal fusion layers of a concave portion bottom and a convex portion top of the inner core material and the thermal fusion layers of the outer packaging laminate material are integrally joined.

    Abstract: A packaging material for a battery includes a base material layer as an outer layer, a sealant layer as an inner layer, and a barrier layer provided between the base material layer and the sealant layer. The sealant layer is composed of a single layer or a multi-layer. The sealant layer includes a first sealant layer serving as an innermost layer made of a propylene-based resin containing an ethylene-propylene copolymer. In the ethylene-propylene copolymer, a ratio Mw/Mn of a weight average molecular weight Mw to a number average molecular weight Mn, measured by a gel permeation chromatography (GPC), is 1 to 7, a melt flow rate measured at 230° C. at a load of 2.16 kg based on JIS K7210 is 5 g/10 min to 30 g/10 min, and a melting point calculated by a differential scanning calorimetry analysis is 120° C. to 135° C.

    Abstract: 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 layer 2 as an outer layer, a polypropylene layer 3 as an inner layer, a metal foil layer 5 arranged between the heat resistant resin layer and the polypropylene layer, wherein at least an inner side surface of the metal foil layer 4 is subjected to a chemical conversion treatment, and the polypropylene layer 3 is laminated on the chemical conversion treatment surface of the metal foil layer via an adhesive layer 5, wherein the adhesive layer 5 is formed by applying an adhesive to the chemical conversion treatment surface of the inner side surface of the metal foil layer 4, 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° C. is 5 g/10 min to 42 g/10 min, and a multifunctional isocyanate compound.
