In the past double tubes were formed by two steps. At first a tube was formed by an oval forming shoulder. In a second step the double tube was formed by pushing the film tube to its final shape.
TwinForm forming shoulders are designed to form the double tube in one forming step. The integration of the forming steps into one part results in a more reliable forming process and a reduced falling height for products.
TwinForm offers packing products into a double chamber bag. Furthermore the double chamber bags can be cut into two single three-side-sealed bags.
