1. Vertical Forming:

• The process begins with a roll of packaging film material. The film is usually a flat roll that is pulled into the machine.

2. Film Unwinding:

• The packaging film is unwound and guided through the machine. It passes through various rollers and guides to ensure proper alignment and tension.

3. Vertical Sealing:

• The film is formed into a vertical tube by a set of forming collars. Vertical sealing jaws then create a continuous vertical seal to form the back of the bag.

4. Product Filling:

• The product is dispensed into the bag through a filling tube. The filling mechanism can be a volumetric filler, auger filler, or another type depending on the nature of the product.

5. Horizontal Sealing:

• Once the product is filled, horizontal sealing jaws create a horizontal seal at the top of the bag, effectively sealing the product inside.

6. Cutting:

• The machine then cuts the sealed film, creating individual packages. The cutting mechanism can be a rotary knife, reciprocating knife, or another cutting device.

7. Final Product Discharge:

• The finished, sealed packages are then discharged from the machine, ready for further processing or packaging.

8. Controls and HMI:

• VFFS machines are equipped with a control system, often featuring a Human Machine Interface (HMI). The HMI allows operators to set parameters such as bag length, fill volume, and machine speed.
