This industrial application profile focuses on post-consumer plastic film and bag recycling plants recovering highly flexible, printed, and low-bulk-density film scrap. It covers agricultural greenhouse films, ground mulch films, stretch wrap (LLDPE\/LDPE), shopping bags, and woven polypropylene (PP) raffia sacks.<\/p>\n
Film recycling operators face unique operational obstacles: first, loose film flakes have an extremely low bulk density (0.05\u20130.12 kg\/L) and high surface area, causing severe bridging, fluff floatation, and feed-throat starvation in traditional extrusion hoppers. Second, agricultural and packaging films carry residual moisture, aggressive printing inks, laminating adhesives, and organic residues. When heated inside the extruder barrel, these decompose into foul-smelling volatile organic compounds (VOCs), acidic vapors, and pyrolytic greasy smoke, causing porous pellets and triggering plant environmental shutdown orders. This application integrates heavy-duty shredding\/crushing, force-feed single\/twin-screw extrusion with multi-vent vacuum devolatilization, continuous non-stop melt filtration, water-ring die-face pelletizing, and an engineered multi-stage VOC deodorization system to produce premium, odorless recycled polyolefin pellets.<\/p>\n","protected":false},"excerpt":{"rendered":"
