[0002] In the existing plastic packaging bag processing process, the plastic granule raw materials first need to be made into plastic film through a film blowing machine. During the process, they pass through the casting roller, shaping roller, corona roller, cooling roller and other components in turn. Finally, the plastic film is wrapped and curled on the discharge shaft to form a film roll. Then, the film roll is manually transported to the drum of the slitting machine, and the wider film roll is slit to make its size meet the processing parameters required by the customer. After that, color printing, film cutting, bag making and packaging are carried out to obtain the finished plastic packaging bag.
