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 in the market place to cover horizontal versions of flow-wrappers, sachet machines, blister pack machines, four side seal machines and thermoform fill and seal machines.; in both cases packaging material is fed off a roll, shaped, and sealed. The bags/packs are then filled, sealed and separated.

Today many FFS systems are highly sophisticated featuring computer interfaces and control networks. Greater speed and versatility are the major benefits of FFS systems for user companies. For example snack producers demand systems that have the versatility to provide fast changeover between many different packaging formats to meet growing demand for single serve packs. Here VERTICAL FFS is capable of creating virtually any size or shape ranging from the standard pillow pack to bags sealed on all four sides.

The multiplicity of FFS machines employ a wide range of material types and are used across numerous markets including food, drinks, cosmetics, electronics, stationary, tobacco, chemical, medical, and pharmaceuticals.
