PACKAGING MATERIAL FOR POLYMER CELL AND PROCESS FOR PRODUCING THE SAME

摘要

A packaging material for polymer cells which comprises a laminate (10) comprising a base layer (11), an adhesive layer (17b), a chemical-treatment layer (16b), an aluminum layer (12), a chemical-treatment layer (16a), an adhesive layer (17a), a heat-sealable layer (14), and a liquid-paraffin laye r (15). The adhesive layer (17a) may be replaced with an acid-modified polyolefin layer (13) formed by extrusion or an acid-modified polyolefin res in (18) formed by coating. The heat-sealable layer (14) is made of a polyolefin . Since the heat-sealable layer (14) is coated with the liquid-paraffin layer (15), the packaging material has improved suitability for embossing.
