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.

The XPdius vertical form and seal machine is designed for high speed applications and service-ability. Both sides of the machine open allowing easy access to all parts and assemblies inside the fame. The Xpdius 1700 is able to form and fill bags up to 17 inches wide.

Maintenance mechanics save hours of time with features like tool-less quick removal of change parts and design.
