Form Fill Seal (FFS) machines are packaging machines that form, fill and seal a package on the same machine. The main types are vertical form fill seal (VFFS) and horizontal form fill seal (HFFS) machines – a term often used to cover horizontal versions of flow-wrappers, sachet machines, blister pack machines, four side seal machines and thermoform fill and seal machines.
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
