DJR350 electric thermal shrinking wrapping machine is an exclusive shrinking device for plastic-film labels. It uses a small fan for heating by blowing hot air on the label through correspondent openings via a special air duct. The label then shrinks with the thermal flow. Relying on an electrical heating unit – a finned electrical heating duct –the heat energy can be fully utilized. On the one hand, the small fan can save energy; on the other hand, it won’t suck the label as conventional fans do. So it is more suitable for this industry.
