Automatic Case Sealers

Professional solution for efficient case sealing

Case sealing – simple and time-saving

The fully automatic case sealer is the perfect solution for professional case sealing with high throughput. This model is driven from the side, which ensures optimum case guidance. The case sealer automatically adapts to the respective case formats thanks to automatic format adjustment. The cartons are sealed using machine adhesive tape, which quickly and securely bonds the bottom and top flaps of the shipping cartons. This machine series guarantees ergonomic working (no constant lifting of heavy cartons), clean and straight adhesive seams and low-noise unwinding of the adhesive tape.
