ABSTRACT:
A static seal is applied to overlapping edges of film wrapped about a product. A hollow forming head forms the film into a generally tubular configuration so that longitudinally extending opposite edges of the film overlap. A first electrode is disposed within the tubular cavity defined by the film and bears downwardly upon the overlapped edges of the film as the film travels past the first electrode. A second electrode is positioned downwardly of the overlapped edges and outside the tubular cavity. A stream of electrons flowing across an air gap between the electrodes applies the electro static seal.
