Abstract
A polymer battery module packaging material is a packaging laminated structure (10) including a base layer (11), a first adhesive resin layer (17b), a first chemically converted layer (16b), an aluminum layer (12), a second chemically converted layer (16a), a second adhesive resin layer (17a), a heat-sealable layer (14) and a liquid-paraffin layer (15). The second adhesive resin layer (17a) may be substituted by an acid-denatured polyolefin resin layer (13) formed by extrusion or an acid-denatured polyolefin resin layer (18) formed by coating. The heat-sealable layer (14) is formed of a polyolefin resin. The liquid paraffin layer (15) coating the heat-sealable layer (14) improves the emboss-formability of the polymer battery module packaging material.
