Horizontal Form-Fill-Seal is a piece of equipment that both produces a pouch from roll stock film and spout and cap assemblies, and fills it in the same operation. The film or laminate travels through the machine in a horizontal direction, which gives the machine the “horizontal” description. This process accounts for all parts of manufacturing a complete pouch product, from film unwinding, pouch forming, filling and sealing, as seen below. A benefit of HFFS is that it optimizes the total cost of ownership and allows for more flexibility in sizes and shapes in production. It also provides the manufacturer with total control of their packaging process.
