Technical Solutions for PE PP Film Recycling

Challenge of “PE PP Film Recycling:

Post-consumer film waste, such as PE stretch films and PP woven bags, presents unique challenges in the recycling process due to high surface area, extreme contamination, and water retention.

Unlike rigid plastics, films tend to wrap around rotating shafts and trap water within their folds. Standard plastic recycling line often struggles with throughput and drying efficiency, leading to high operational costs and lower-grade end products.

Efficiently processing these “soft materials” requires a specialized mechanical approach to ensure the final flakes are clean, dry, and ready for pelletizing.

BEIER’s Technical Innovations:

1. Heavy-Duty Wet Crushing: Our systems use specialized blade geometries designed for film. By introducing water during the crushing stage, we initiate the cleaning process immediately and reduce blade wear by cooling the friction-generated heat.
2. Advanced Friction Washers: High-speed centrifugal friction is used to “scrub” the film surface, removing organic residues and adhesives that cold soaking cannot reach.
3. Mechanical & Thermal Drying Combination: To reach a moisture content below 2%, we combine mechanical squeezer technology with thermal pipe drying. This ensures that even the most absorbent films are bone-dry before entering the extruder.

PE PP Film Recycling FAQ:

Q: How do I handle high moisture in post-consumer films?

A: We use advanced Squeezing Dryer technology. Unlike centrifugal dryers, our squeezer uses mechanical pressure to reduce moisture to under 3-5%, ensuring the material is perfectly prepped for the pelletizing stage.

Q: Can BEIER lines process heavily printed or soiled PE/PP films?

A: Yes. Our system features a Multi-stage Friction Washer and Hot Wash tanks specifically designed to remove stubborn inks, adhesives, and organic contaminants from film surfaces.

Q: Is it possible to recycle both PP woven bags and PE films on the same line?

A: Absolutely. Since both are polyolefins with similar densities, our lines are optimized to process both. The PLC system allows for quick adjustments to handle different material bulk densities.
