Horizontal ultrasonic sealing technology by Herrmann Ultrasonics

In common versions of horizontal form fill seal (HFFS) machines, packaging material is fed of a roll to a form shoulder, shaped into a tube, and sealed longitudinally. Then the bag is filled, sealed horizontally and seperated. The welding of the cross seal simultaneously creates the top seal of the filled tube and the bottom seal of the next bag at the same time. Herrmann produces sealing systems and modules for both HFFS and VFFS packaging systems. In addition, independent add-on modules such as valve and zipper applicators are available.
