The CT 303 TB is a semi-automatic case sealer compatible with PP and PVC tape, specifically designed for low-height cartons or taller boxes with a compact footprint. After the box is filled, the operator manually folds the top flaps and inserts it into the sealer, where both the top and bottom flaps are automatically taped. Dual top and bottom drive belts ensure steady transport and a secure, high-quality seal.

The CT 303 TB can be quickly adjusted to the required box width and height, enabling the efficient sealing of thousands of cartons per day.
