This fully automatic side sealing machine comes with a high-speed heat shrink tunnel that uses recirculating air flow technology to provide optimum shrink performance. It is also designed with a servo motor and a temperature control system, enabling objects to be heated, sealed and cut at a constant temperature. In addition, our machine is equipped with a variable-speed front feeding system and a rear stacking table. All this adds up to a completely unmanned operation. Saving large amounts on labor costs. The operating speed varies from 30 to 80 packs per minute.
