The PP/PE Soft Material Washing Line is a high-performance, fully automated recycling system designed to process post-consumer soft plastics such as polypropylene (PP) and polyethylene (PE). The line efficiently converts waste materials—including films, bags, and flexible packaging—into clean, high-quality flakes suitable for extrusion, pelletizing, or molding.

Engineered with precision and durability in mind, the system combines advanced mechanical components, intelligent separation technology, and energy-efficient drying units to ensure consistent output, minimal contamination, and reduced operational costs. Its modular design allows customization according to plant size and production requirements, making it suitable for small, medium, and large recycling operations.

Working Principle

The PP/PE Soft Material Washing Line operates through a systematic multi-stage process to achieve thorough cleaning and preparation of soft plastic waste:

1. Shredding: Soft plastics are fed into the shredder, where they are cut into uniform pieces to facilitate efficient washing.
2. Floating Washing: Materials enter the floating washer, which separates light contaminants, floating debris, and unwanted impurities.
3. Friction Washing: Washed plastics are scrubbed mechanically in friction washers, removing adhesives, labels, and stubborn dirt.
4. Pre-Crushing: The pre-crusher reduces the washed materials into smaller, uniform fragments suitable for downstream processing.
5. Drying: Squeezer dryers and pipeline dryers efficiently remove moisture, achieving low residual water content and preserving flake quality.
6. Separation & Storage: Trommel screens separate oversized particles, while cyclone silos provide temporary storage of cleaned flakes.
7. Material Handling: Belt conveyors transfer materials smoothly between units and into jumbo silos, ensuring uninterrupted workflow.

By following this process, the line transforms post-consumer PP/PE waste into clean, high-quality flakes suitable for reuse in extrusion, pelletizing, or molding applications, providing a reliable, environmentally responsible recycling solution.
