Vertical Seal is Not in the Center of the Bag

Faults forming the vertical seal

Check the position of the forming shoulder (and turning lug of the forming shoulder) relative to the vertical sealing surface of the filling tube and adjust as necessary.

• Check the centered effect of the vertical sealing unit.

• Check the packaging material, turning or overlap zone according to the format drawing.

• Is the packaging material sufficiently wide? - With very elastic and very thin packaging materials or a tendency for the packaging material to roll, the planned overlap width may vanish. A roller, which is 5 mm wider, would be necessary here.
