Table models with cut-off knife suitable for the production and sealing of foil bags. The weld length is 300 or 400 mm depending on the modification. The weld is made with a 2 mm wide kanthal weld plate. The device is characterized by high operator safety - the knife comes out only after pressing the upper jaw to the lower one. The cutting of the foil is done about 6 mm behind the weld. A suitable complement to these models is a table-top unwrapper for film widths up to 300 or 600 mm. This model is designed for welds up to 300 mm.
