Horizontal FFS
On horizontal machines, the film is folded so that the fold is at the bottom. As the feeding is horizontal, the bags are then sealed laterally by vertical bars, and opening devices spread the top edges allowing the product to be filled. These are then sealed, separated, and (sent on the conveyor) discharged at the end of the machine.
The film is formed at the same time as the zipper is inserted. The contents is then filled and the bag is sealed. HFFS machines are ideal to pack food, pharmaceutical and cosmetic products.
The in-line zipper application is ideal for stand-up pouches (stand-up, such as Doypack bags…)
Advantages of HFFS machines:
- Increased production speed
- Better finish and quality of the bags
- More complex bag shapes
- Possibility of aseptic packaging
- Production speed (making 2 bags at the same time at an average of 60 bags/min)
