Bag sealing machines

Syntegon bag closers are ideally suited for a variety of applications from medical and food to non-food items. Our machines feature an advanced sealing technology to ensure bags are properly sealed, especially for medical applications that require hermetic sealing. Our horizontal bag sealers feature an HMI that is situated at the ideal height for the operator, and pivots to allow access on the conveyor side of the system. Syntegon bag closers come in all stainless steel for a hygienic design.
