Abstract
A housing film for electrochemical elements includes a barrier layer having a polymeric structure which has been deposited from the gas phase on to a support layer, an electrochemical element which has at least one positive electrode and at least one negative electrode and has at least one such film. A process for producing the electrochemical element includes steps wherein at least two electrodes are applied next to one another on a substrate and are covered with a film, where the substrate and/or the film is such a housing film.
