Abstract
A method for welding material including: applying a release material to a first film, the release material applied to locations where a weld is not desired; positioning a second film opposite the first film, the release material being positioned between the first film and the second film; placing the first film and the second film between planar press plates having planar surfaces and closing the press plates on the first film and the second film; applying energy to at least one of the press plates to weld the first film to the second film where the release material is absent.
