PP PE film washing line

The PP PE film washing line is an advanced and highly efficient recycling system specifically designed for the processing of post-consumer polypropylene (PP) and polyethylene (PE) plastic films. It is widely used for recycling materials such as agricultural films, packaging films, shopping bags, stretch film, and industrial scrap, converting heavily contaminated waste plastics into clean, reusable raw materials. 　　

This production line integrates multiple processing stages, including material feeding and sorting, size reduction through shredding or crushing, intensive washing, rinsing, and high-efficiency drying. Each stage is carefully engineered to address the unique characteristics of lightweight and flexible plastic films, ensuring thorough removal of contaminants such as sand, soil, ink, oil, organic residue, and labels.

During the washing process, a combination of cold washing, friction washing, and optional hot washing effectively separates impurities while preventing material entanglement and loss. Floating washing tanks take advantage of the density difference between PP/PE and heavier contaminants, allowing dirt, stones, and metal particles to settle and be discharged. High-speed friction washers further enhance cleaning performance by removing stubborn surface residues. 　　

The drying section typically consists of centrifugal dewatering machines and thermal drying systems, which significantly reduce moisture content and improve material consistency. This ensures that the final output meets the cleanliness and dryness requirements for downstream processes such as pelletizing, extrusion, or injection molding. 　　

Equipped with an automatic control system, the PP PE film washing line enables stable operation, precise process control, and reduced labor intensity. Energy-saving designs and optional water recycling systems help lower operating costs while supporting environmentally responsible recycling practices.
