Form Fill Seal Machines

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. 

How does a form fill seal machine work?

In FFS machines, packaging material is fed off a roll, shaped, and sealed. The bags/packs are then filled, sealed and separated.

Many FFS systems are highly sophisticated and feature 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. Vertical FFS machines are capable of creating virtually any size or shape. These range from standard pillow packs to bags sealed on all four sides.

Which products are packaged by FFS machines?

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

Products commonly packaged by form, fill, seal include:

Nuts, Sugar, Crisps, Rice, Pulses, Sweets & Confectionery, Sauces & Soups, Pet Foods, Grain, Jams & Preserves, Cakes, Bread, Biscuits, Teabags,Condiments, Capsules and Pills, Greetings Cards, Phone Cards
