SR20 is a semi-automatic carton 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.
