Complete Guide to PP Woven Bag Recycling
UN machine à laver les sacs tissés is a professional recycling system designed to process polypropylene (PP) woven bags, jumbo bags (FIBCs), raffia bags, and similar plastic materials. These industrial machines convert dirty post-consumer woven bags into clean plastic flakes suitable for extrusion or pelletizing.
Such systems are essential for reducing global plastic waste and supporting the circular economy.

Key Features & Process Flow
1. Shredding & Size Reduction
The recycling process begins by feeding the waste woven bags into industrial shredders or crushers.
These machines reduce the bags into smaller flakes, improving washing efficiency and reducing energy consumption during downstream processes.
2. Cleaning & Washing
The shredded material then passes through multiple cleaning units such as:
- Rondelles de friction
- Floating wash tanks
- High-speed scrubbing units
These remove:
- soil
- labels
- sand
- oil residues
- other contaminants
Stainless steel construction ensures long service life and stable performance.
3. Separation & Impurity Removal
To ensure high-quality recycled flakes, the system integrates several separation units:
- Magnetic separators
- Trommel screens
- Density separation tanks
These eliminate metals, stones, and other non-plastic impurities.
4. Dewatering & Drying
After washing, the wet flakes enter:
- Machines de déshydratation centrifuges, et
- Hot air dryers ou sécheurs centrifuges
These systems reduce moisture to 5–8%, which is ideal for extrusion or pelletizing.
5. Storage & Pelletizing Preparation
Clean, dry flakes are stored in silos or buffer tanks before being sent to the extrusion or pelletizing line.
This step stabilizes feeding and ensures consistent pellet quality during the final stage.
6. Intelligent Control Systems
Modern woven bag recycling lines include:
- PLC systems
- Touchscreen control
- Real-time monitoring
- Automated flow management
This ensures stable operation, reduced downtime, and easier maintenance.
Applications
Woven bag washing machines are widely used in:
- PP woven bag recycling plants
- Jumbo bag recycling facilities
- Plastic film & raffia recycling factories
- Countries with high woven bag waste (India, Vietnam, China, Indonesia)
These systems help recyclers transform post-consumer waste into valuable raw materials for new product manufacturing.
Résumé
UN machine à laver les sacs tissés is a complete PP woven bag recycling solution that integrates shredding, washing, drying, and impurity separation. It converts dirty waste woven bags into clean, reusable PP flakes or pellets.
By combining multiple processing stages into a single automated system, it supports efficient plastic recovery and promotes sustainable recycling operations.
