SR20 is a Semi-Automatic Case Sealer with Random Adjustment.

SR20 represents the ideal solution when your packaging line processes boxes with different dimensions.

Thanks to the 4 belts box control, the sealing process is always guaranteed without jams, also in case of overstuffed and empty boxes.

Moreover, the pneumatic system allows a fast adaptation to a large range of box dimensions.

The robust dual masts frame and the branded components make the SR20 ready for round-the-clock applications. The historical reliability of SIAT machines is fully guaranteed.

The fast-removable taping head, the easy access to the motors and the clear cable management allow an efficient check of the machine, facilitating maintenance operations.
