For Washed PP PE Film, Non-woven fabrics, and Woven bags. Cut moisture to 1–5%, densify flakes and stabilize extruder feeding.
Challenges in Plastic Film Recycling
Recycling post‑consumer films is hard because washed films often retain high moisture. Common pain points include:
- High Moisture Content: Washed film can contain up to ~40% water, complicating handling and drying.
- Ineffective Drying: Lightweight flakes trap water; vertical or hot‑air dryers often leave 20–30% residual moisture.
- Recycling Issues: Excess water causes inconsistent extruder feeding and lowers throughput.
Working Principle
1) Feeding
Washed PP/PE film and woven/non‑woven offcuts enter via conveyor or hopper. The material may contain 10–35% moisture after washing.
2) Squeezing Process
- A high‑torque screw forces material through a perforated barrel.
- Pressure and shear expel water through the perforations.
- Frictional heating stays low to minimize polymer degradation.
3) Dehydration
- Water exits through the mesh; condensate/drain is collected for treatment.
- Typical final moisture reaches 1–5% (material‑dependent).
4) Extrusion / Densification
- Material compacts into high‑density lumps or short strands.
- Optional cutter sizes the discharge for easy feeding into pelletizing extruder.
5) Discharge
Dried, densified material conveys to storage, agglomerator or directly to the compactor‑extruder.
Main Features
Efficient Moisture Reduction
Reduces typical 10–35% moisture down to 1–5%, enabling stable downstream processing.
Density & Volume Optimization
Transforms loose film into dense lumps for faster, consistent extruder feeding.
Accelerated Drying
Higher throughput than centrifugal or hot‑air drying for washed film and woven waste.
Minimized Heat & Degradation
Low thermal load preserves polymer quality and pellet value.
Extrusion‑Ready Output
Optimally prepares material for compactor‑extruder pelletizing lines.

FAQ
What materials can it process?
Washed PP/PE films, non‑woven fabrics, woven bags and similar thin‑wall flexible packaging. Contact us for other polymers.
What is the typical final moisture?
Material‑dependent, typically 1–5% after squeezing, versus 20–30% after hot‑air/vertical drying alone.
Where does it fit in my line?
After the washing line and before the compactor‑extruder pelletizing stage.
Will the material overheat?
No—low thermal load minimizes degradation. Temperature rise is controlled compared with thermal dryers.
