The CT 303 SDF is a fully automatic taping unit designed to alternate between two types of bottom closure: standard 50 mm PP tape or hot melt. This flexibility is ideal for production lines where different batches require different closing methods.

Boxes arrive from a powered conveyor with the top flaps open. As each carton enters the machine, the upper flaps are automatically folded, and both the top and bottom are sealed. The machine can be manually set to the required box size and easily switched between top-and-bottom sealing or top-only sealing. Motor-driven side belts ensure smooth transport and consistently high-quality sealing.

With the CT 303 SDF, you can professionally seal hundreds of cartons per day.
