<P>PROBLEM TO BE SOLVED: To provide a packaging material for batteries, which achieves high dampproofing as an outer package. <P>SOLUTION: The packaging material for batteries forms an outer package of a battery, into which a battery body is inserted and the periphery of which is sealed by heat-sealing. The packaging material for batteries is a laminated body composed of at least a base material layer, a barrier layer, a chemical conversion treatment layer, an adhesive layer, and a sealant layer. The adhesive layer of the packaging material for batteries contains a component having a functional group which reacts with water, and is formed by using any one of a dry lamination method, extrusion lamination method, sandwich lamination method, and coextrusion lamination method. <P>COPYRIGHT: (C)2010,JPO&INPIT |
