Because the density of Polythene bags or Polypropylene bag are very small. Using traditional plastic recycling machine to recycle plastic bag, the capacity is much smaller than recycle plastic flakes. In order to ensure the production capacity, Genius Plastic Bags Recycling Machine combined shredder or crusher, extruder, and pelletizer. The cutter compactor creates friction heat while it is cutting plastic bags. It compacts the bags to higher density. Then it feeds materials to extruder to increase the capacity.
