special traction mechanism adopted in our equipment, the traction force of film is very small so that the deformation of film is very small, which guarantees the safety of packing.
3. Human-machine communication in real sense. All the controls are realized directly through touch screen. After the production parameters such as temperature, speed, bag length, sealing and cutting time and filling quantity are set on the touch screen, PCC will directly send signals to each actuator to realize the a
