FFS (Form Fill and Seal) Film
The Vertical form fill sealing machine (FFS) is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food, minerals and chemicals as well as a wide variety of other products. The machine constructs plastic bags out of a flat roll of plastic 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 polythene film, which has had labelling and artwork applied to the exterior or interior of the film.
The film approaches the back of a long hollow conical tube, and when the centre of the plastic is near the tube, the outer edges of the film form flaps that wrap around the conical tube. The film is pulled downward around the outside of the tube and a vertical heat-sealing bar clamps onto the edges of the film, bonding the film by melting the seam edges together.
