A vertical form fill seal (VFFS) machine is a packaging machine used to form, fill, and seal flexible pouches or bags typically used for packaging various products such as snacks, grains, powders, liquids, and more. Here's a basic rundown of how vertical form fill seal machine works:
Film Feeding: The vertical form fill seal machine starts by feeding a roll of packaging film, usually made of materials like polyethylene or laminate, vertically downwards.
Film Forming: The film is pulled downward and formed into a tube shape by a forming tube or collar. The edges of the film are sealed together vertically to create a continuous tube.
Cutting: After sealing, the machine cuts the continuous tube of filled and sealed pouches into individual units. This is typically done using a cutting knife or blade.
Product Discharge: The finished pouches/bags are then discharged from the machine, usually onto a conveyor belt or into a collection bin for further processing or packaging.
Throughout this process, the vertical form fill seal machine operates continuously, forming, filling, sealing, and cutting pouches at a high speed to achieve efficient packaging production. Advanced VFFS machines may also include additional features such as printing date codes or batch numbers onto the pouches during the sealing process.
