Vertical Form Fill Seal (VFFS) Machine: –

The Vertical Form Fill Seal (VFFS) machine is an automated packaging solution that creates, fills, and seals pouches from a continuous roll of film. It is commonly used for high-speed packaging of food products in a compact, flexible format.
Working Mechanism
A flat roll of film is shaped into a tube by passing through a forming collar.
The machine seals the bottom end of the tube to create a pouch.
The food product (powder, granules, or liquid) is dispensed into the pouch.
The top of the pouch is sealed and cut, creating an individual package.
