Bag closing for Pre-Made Bags
Syntegon’s range of bag sealers / closers are ideal for every application from medical and food to non-food items. Each machine comes with superior sealing technology to ensure pre-made bags are properly sealed, especially for medical applications where hermetic sealing is required. For horizontal bag sealers, the HMI is mounted to be at the ideal height for the operator and the HMI pivots to allow access on the conveyor side of the system. Lastly, bag closers come in all stainless steel for a hygienic design.
