Abstract
This packaging material for electrochemical cells has an identification mark that can be recognized from the outside and that is difficult to forge. The packaging material includes a multilayer film which has a structure formed by laminating a base layer (), an adhesive layer (), a metal foil layer (), an acid-modified polyolefin layer (), and a heat-sealable layer () in this order, wherein the base layer () contains both a oriented polyester film () and a oriented nylon film () with a printed layer () provided on the surface of the oriented polyester film () that faces the oriented nylon film ().
