The Double-stage String-type PE/PP Granulating Line is an advanced plastic pelletizing production line designed for manufacturing PE (Polyethylene) and PP (Polypropylene) pellets. These high-quality pellets are widely used in the production of plastic bags, woven bags, ropes, fishing nets, containers, toys, automotive parts, and packaging materials due to their excellent physical properties and chemical stability.
With high strength, toughness, and chemical resistance, the pellets are suitable for a wide range of environments and applications. Moreover, the combination of low material cost and the efficient pelletizing process, which can utilize recycled materials, helps significantly reduce production costs.
