What is an automatic vertical form fill seal packaging machine?

A vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food, and a wide variety of other products. The machine constructs plastic bags and stand-up pouches out of a flat roll of film, while simultaneously filling the bags with product and sealing the filled bags. Both solids and liquids can be bagged using this packaging system.

The typical machine is loaded with a continuous flat roll of plastic film, which has had labeling and artwork applied to the exterior or interior of the film. Note that while plastic is the most commonly used packaging material in the food industry, the technology can also be used to form continuous metalized foil/film, paper, and fabric product containers by changing the edge sealing/seaming methods. For some products the film may first be fed through a sterilizing chemical bath and dryer prior to use in the packaging system.
