The PP PE film washing line is an advanced recycling solution designed for the high-capacity processing of post-consumer polypropylene (PP) and polyethylene (PE) films. Engineered to handle heavily contaminated plastic waste, this system converts discarded films into clean, high-purity flakes suitable for reuse in premium manufacturing applications.
Ideal for modern recycling facilities, the system delivers consistent performance, reduced operating costs, and strong environmental benefits—making it a key asset in the circular plastics economy.
Wide Range of Applications
This PP PE film recycling system is suitable for processing various types of soft plastic waste, including:
- Agricultural films (mulch films, greenhouse covers)
- Post-consumer packaging films
- Plastic shopping bags and carrier bags
- Stretch films and shrink wraps
- Industrial plastic scraps
By efficiently removing contaminants such as dirt, sand, oils, adhesives, and printing inks, the washing line ensures maximum material recovery and output quality.
Complete PP PE Film Washing Process
The system integrates multiple stages optimized for lightweight and flexible film materials, ensuring thorough cleaning and smooth operation:
1. Feeding and Pre-Treatment
Automated feeding systems combined with pre-sorting units remove large impurities and ensure a stable material flow into the line.
2. Shredding and Size Reduction
Heavy-duty shredders or crushers reduce films into uniform flakes, increasing surface area for better washing efficiency.
3. Multi-Stage Washing System
The washing section includes a combination of:
- Cold washing tanks
- High-speed friction washers
- Optional hot washing units
Float-sink separation tanks take advantage of PP/PE density properties, allowing plastics to float while heavier contaminants (sand, stones, metals) settle and are removed automatically.
4. Intensive Friction Cleaning
High-speed friction washers provide powerful mechanical cleaning, effectively removing stubborn contaminants such as glue, labels, grease, and organic residues.
5. Dewatering and Drying
Centrifugal dewatering machines remove most surface moisture, followed by thermal drying systems that reduce moisture content to optimal levels for pelletizing or extrusion.
Key Features and Advantages
- High Throughput Capacity – Designed for continuous, large-scale operation
- Superior Cleaning Efficiency – Multi-stage washing ensures high-purity output
- PLC Intelligent Control System – Real-time monitoring for stable and automated operation
- Energy & Water Saving Design – Optimized motors and optional water recycling system

High-Quality Output for Reuse
The final product—clean and dry PP/PE flakes—meets the strict quality standards required for:
- Plastic pelletizing
- Film blowing
- Sheet extrusion
- Injection molding
This allows recyclers to produce high-value recycled pellets that can effectively replace virgin plastics in many applications.
