Recycling Challenges
Why PP Woven Bags & Raffia Requires a Specialized Recycling Process
The line has to remove contamination while keeping pp woven bag moving steadily through washing, dewatering and drying.
-
01 Printing & Coatings
Ink and laminated coatings affect both washing and melt filtration.
-
02 Dust & Fines
Sacks carry fine dust and powder residue that must be removed early.
-
03 Variable Density
Woven structure behaves differently from film during washing and drying.
-
04 Fibre Entanglement
Raffia strands can wrap around rotating parts without proper size control.
Output Routes
Choose the Output for Your Recycling Project
-
Route A Clean PP Woven Bag Flakes
Washed and dried flakes for in-house processing, separate pelletizing or sale as prepared recycled material.
- Size reduction and washing
- Separation and dewatering
- Drying to a stable flake condition
-
Route B Recycled Pellets
A continuous route from contaminated pp woven bag to filtered recycled pellets for suitable downstream applications.
- Washing line matched with extrusion
- Degassing and melt filtration
- Pellet cooling, storage and handling
Output specification depends on the incoming material and the target application.

FAQ
Questions PP Woven Bag Recyclers Usually Ask
What moisture level is achieved after drying?
Moisture after drying is typically below 5%, depending on the dewatering and drying configuration.
How are fines handled?
Where the material generates a lot of fines, a squeezer can replace the dewatering machine in the drying stage.
Is the material crushed wet?
Yes. Wet crushing generally gives a better result for woven bags — it suppresses dust and improves the washing effect.
Can laminated or coated bags be processed?
Yes. The route is adjusted for the coating type, and melt filtration is configured accordingly.
Do woven bags need shredding before washing?
Yes. Shredding to a controlled strip size keeps the material moving steadily through washing and drying.
Which output is more common for woven bags?
Pellets are common because the recycled granulate is easier to reuse in downstream extrusion.
What should I send before quotation?
Bag type, coating and printing condition, required capacity and target output.
