Plastic Film Recycling Machine

Plastic film offcuts, edge trim, and rejected bags from production lines don't have to go to waste — a PP recycling machine reprocesses this scrap material back into reusable resin pellets that can re-enter the extrusion process. For bag manufacturing and stationery production facilities, in-house recycling reduces raw material cost, minimizes disposal expense, and supports sustainable manufacturing practices. Ming Jilee's MGB-RPW-65 is a pelletizing and recycling system designed for PP, LLDPE, LDPE, and HDPE waste film, outputting 55–80 kg/hr in a compact footprint that fits within an existing production floor. The round die is made from nitride steel and hardened for maximum service life, while the rotary knives use tungsten carbide material for durability and fast changeover without adjustment. The extruder feeds melt to round die precision boreholes, where high-speed rotary knives cut the melt as it exits; centrifugal force pushes the pellets outward into a high-speed rotating water ring that cools and transports them through a water channel to a separator. A dehydration system then dries the pellets to a constant residual moisture level before collection and repackaging for reuse. CE certified, ISO-9002.
