SEAL Technology

Compact. Clean. Sealed.


The SEAL technology prevents material loss as an inflatable sleeve in a specially designed filling spout inflates during the filling process. After dust-free filling, the bag is carefully extracted from the spout and the specially designed bag valve is welded shut by an ultrasonic sealing system. Most producers see a payback on their SEAL technology investment in less than 12 months.
