The automatic 600–2,000 kg/h PP PE film woven bag washer is a high-capacity cleaning system designed for plastic recycling plants that process post-consumer and post-industrial polyethylene and polypropylene waste.It efficiently removes soil,sand,dust,labels, food residue,oils,and other surface contaminants from waste plastic film,woven bags,and flexible packaging materials before further recycling.
Designed for continuous operation,the washing system combines size reduction,friction washing,rinsing,dewatering,and drying technologies to prepare clean plastic flakes for pelletizing or other downstream recycling processes.

Typical Washing Process
Depending on the material and required cleanliness,the complete pp pe film washing line may include the following stages:
1. Feeding and pre-sorting
Waste film and woven bags are loaded into the feeding system.Oversized items,metals,stones,and non-plastic materials can be removed during manual or automated sorting.
2. Shredding or size reduction
A heavy-duty shredder or crusher reduces the material into smaller pieces,allowing contaminants to be removed more effectively during washing.
3. Pre-washing
The pre-washing unit loosens and removes loose dirt,sand,and other heavy contaminants before the main washing stage.
4. Friction washing
A high-speed friction washer uses mechanical agitation and water to clean the plastic surface and remove embedded contamination.
5. Float-sink separation
The washing system can separate floating PP and PE materials from heavier materials such as stones,metals,glass,and certain unwanted plastics.
6. Hot or cold washing
Depending on the feedstock,the system may be configured for cold washing or hot washing with detergent to remove oil,grease,adhesives,and difficult residues.
7. Rinsing
Clean water rinsing helps remove loosened dirt,detergent,and remaining contaminants from the plastic flakes.
8. Dewatering
A centrifugal dewatering machine removes most of the surface water from the washed material.
9. Thermal drying and air separation
A hot-air drying system can further reduce moisture.Air separation may be used to remove lightweight labels,dust,and film fines.
10. Clean material discharge
The washed and dried flakes are discharged for storage,extrusion,pelletizing,or additional processing.
Designed for Plastic Recycling Applications
This PE PP film recycling line is suitable for recycling operations that process:
- Post-consumer shopping bags and packaging film
- PP woven sacks and bulk bags
- Agricultural mulch film and greenhouse film
- Industrial stretch film and wrapping film
- Food and consumer packaging film,subject to appropriate pre-sorting
- Production scrap from plastic bag and film manufacturers
- Mixed PP/PE flexible plastic waste
The cleaned material can be used as feedstock for plastic extrusion and pelletizing,depending on the polymer type,contamination level,sorting accuracy,and final product requirements.
Advantages for Recycling Plants
High Throughput
With available capacities from 600 to 2,000 kg/h,the pp woven bag recycling line can serve small,medium,and large-scale plastic recycling facilities.Equipment configuration can be selected according to the required output and available installation space.
Effective Contaminant Removal
The combination of mechanical friction,water washing,rinsing,separation,and drying provides efficient cleaning for heavily contaminated film and woven bag waste.
Reduced Manual Labor
Automatic feeding,material conveying,water circulation,and discharge systems help minimize manual handling and improve overall plant productivity.
Flexible Configuration
The film woven bag cleaning system can be configured with different equipment combinations,including shredders,crushers,pre-washers,hot-wash tanks,friction washers,float-sink tanks,dewatering units,thermal dryers,compactors,and pelletizing systems.
Improved Feedstock Quality
Consistent washing and drying help produce a more uniform recycled material stream,supporting stable operation of downstream extrusion and pelletizing equipment.

Capacity and Output Considerations
The actual production capacity and final material cleanliness depend on several factors,including:
- Type and thickness of the film or woven bag
- Percentage of PP,HDPE,LDPE,and other polymers in the feedstock
- Soil,sand,oil,and organic contamination levels
- Moisture content of the incoming material
- Degree of pre-sorting
- Required washing quality
- Operating temperature and water conditions
- Selected drying and conveying configuration
For optimal results,materials should be pre-sorted to remove hazardous items,metals,stones,PVC,PET,and other incompatible polymers before entering the washer.
