This guide provides solutions to the three main challenges of PP/PE film recycling: (1) inconsistent feeding, solved by a compactor feeder; (2) impurities from inks and moisture, solved by a two-stage degassing extruder; and (3) production downtime, solved by a non-stop hydraulic screen changer. It positions a purpose-built PE film pelletizing machine with these features as the essential equipment for turning difficult film scrap into a high-profit product.
