A battery casing (10) comprises a base film (12) of plastics material e.g. heat-shrinkable plastics, a metallised coating (14) on its outward facing surface and a layer of adhesive (18) on its inner surface to adhere the casing to the battery shell (22). The metallised coating (14) may have a layer of primer (16) to render it receptive to print. <IMAGE> |
