The polypropylene for a non-polar material, for example, poor adhesion to polar materials such as ethylene-vinyl alcohol copolymer, a polypropylene for the purpose of improving adhesion modified technique widely with an unsaturated carboxylic acid or its derivative Are known. Further, polypropylene is inferior in flexibility, when used as an adhesive is usually blended with soft rubber components to polypropylene.
[0003]
Thus polypropylene compounding soft rubber components, although the adhesive of the polypropylene which adhesion is improved can be obtained (e.g. Patent Documents 1 and 2), while the soft rubber components are deep drawing and bending it will cause whitening upon secondary processing such as was also required improvement in whitening resistance. Especially deep drawing or bending concrete applications as food packaging materials and building materials required include packaging material such as a lithium ion battery.
[0004]
Lithium ion batteries Among these is expanding the use of the like in recent years portable electronic devices and automobiles, further by responding to flexibility and miniaturization of the shape in the lithium ion battery, a pouch type in which the multilayer film and packaging material use of or emboss type of exterior body is expanding. Packaging material formed of the multilayer film, at least a base material layer, a metal foil layer and the heat-adhesive resin layer, and comprised of an adhesive layer for bonding the two layers adjacent of these layers. Since the multilayer film has a large degree of freedom in shape and easily processed in making the exterior body of a pouch type or embossed type, when deforming the multi-layer film, there are cases where deformation portion is whitened. Since there is a whitening places the outer body causing a short, are required material excellent in whitening resistance.
