  • Method and apparatus for forming, filing and sealing tubular packaging
    Publication number: 20020148204
    Abstract: A method and apparatus for forming a tubular package is disclosed. A longitudinally advancing strip of film material is guided about a mandrel so as to form a tubular body. As the film advances, margins of the film at the longitudinal edges are guided together into a fin and the fin is guided against the tubular body portion. The edge margins are then welded to each other and to the tubular body portion to form a tube closed cylinder. Individual packages may be formed and filled using conventional form, fill and sealing equipment.
