A vertical form fill and seal (VFFS) machine is a versatile piece of equipment used in automated production lines to create, fill, and seal packages. Here’s a breakdown of how it works:

1. Forming the Bag: The machine unwinds a roll of flat plastic film, which is then guided by a forming tube. This tube shapes the film into a pouch of the desired size.

2. Filling the Bag: Once the pouch is formed, it’s held open by a clamp. The product is then dispensed into the open pouch using a variety of filling mechanisms depending on the product characteristics. This could be by weight, auger, pump, or volumetric cup depending on the product’s consistency.

3. Sealing the Bag: After filling, the pouch is heat-sealed closed at the top. Some machines can also create a seal at the bottom of the pouch, depending on the desired style (e.g., pillow pouch vs. doy pouch).

4. Trimming and Completing the Package: After sealing, the pouch is cut from the remaining film. The finished package can then have additional features added, such as a date code, a tear notch for easy opening, or a hole punch for hanging.
