Usage and Characteristics
It is used for producing valve cement paper bags with printing. The main motor adopts frequency conversion motor to save more electricity and regulate speed more freely. The color code tracker with good performance makes the sealing and cutting length more accurate and the error smaller. It adopts advanced computer to adjust length more freely and accurately.It can make one printed bag and three unprinted bags one time, or four unprinted bags one time in allowed width.
