W&H packaging machines are based on the FFS principle (form, fill, seal), i.e. sack production, filling and closing is performed in one single operation. This represents the highest productivity level achievable in the filling process.
The machines are designed for packaging free flowing bulk products, e.g. plastic resins, fertilizers, salts and chemical products.
Printed as well as unprinted side gusseted tubing made from plastic film can be converted – a packaging material which offers significant cost advantages compared to premade sacks, as well as more flexible sack filling and sealing
