Recycling Challenges
Why LDPE/LLDPE Film Requires a Specialized Recycling Process
The line has to remove contamination while keeping ldpe/lldpe film moving steadily through washing, dewatering and drying.
-
01 Low Bulk Density
Film occupies large volume per tonne and needs compaction or controlled feeding.
-
02 Moisture Retention
Water is held between film layers and demands mechanical dewatering.
-
03 Printing Ink
Ink and coatings may require hot washing or filtration depending on the output.
-
04 Entanglement
Flexible film must be kept moving without bridging or wrapping around shafts.
Output Routes
Choose the Output for Your Recycling Project
-
Route A Clean LDPE/LLDPE Film 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 ldpe/lldpe film 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 LDPE/LLDPE Film Recyclers Usually Ask
What moisture level can the line achieve?
The dried film output is typically below 3% moisture, depending on the material form and the drying configuration.
How much water does the line consume?
Water consumption is typically 8–12 t/h, depending on the configuration and the contamination level of the film.
What if the film carries a lot of sand?
Heavy sand loads are handled by a drum separation step before crushing and washing, which takes the grit out ahead of the washing stages.
Can water treatment equipment be included?
Yes. Water treatment is configured around the contamination type and the water consumption of the line.
Can the line handle heavily printed film?
Yes. Hot washing and melt filtration stages can be added depending on how much ink has to be removed.
Why is compaction used?
Compaction raises the bulk density of film so it can be fed into the extruder steadily.
Flakes or pellets — which route suits film?
Pellets are common for film because the low bulk density of flakes makes transport and re-feeding harder.
What should I send before quotation?
Film type, ink and moisture condition, baled or loose feed, required capacity and target output.
