1
Feed Opening + Wet Shredding
Bales or loose film are opened and reduced to manageable size so the line can avoid wrapping, surge feeding, and downstream tangling.
Film Recycling Systems
Plastic Film Recycling Lines for PP/PE Film and Woven Bags
Recover low-bulk-density film, stretch wrap, agricultural film, and raffia bags with a process built around washing efficiency, moisture reduction, and stable pelletizing. Typical lines combine wet shredding, friction washing, screw squeezing, and optional cutter-compactor extrusion.
Film Recovery Workflow
Process routing designed for low bulk density, heavy contamination, and difficult drying conditions.
2
Friction Washing + Density Separation
High-speed washers scrub off paper, mud, labels, and glue while sink-float tanks remove heavy contamination such as stones, sand, glass, and incompatible plastics.
3
Mechanical Squeezing and Drying
A screw squeezer or matched drying package reduces residual moisture and increases bulk density, which is critical before extrusion or bagging.
4
Optional Pelletizing Integration
For pellet output, densified film feeds a cutter-compactor or direct extruder with degassing and filtration sized to handle printed and post-consumer material.
Why These Lines Work Better on Film
More Stable Feeding of Fluffy Material
Low-bulk-density film is prepared and densified before extrusion, reducing bridging, starving, and melt-pressure fluctuation.
Lower Moisture Before Pelletizing
Squeezing and staged drying can take washed film into a more practical moisture window for extrusion, storage, or sale as clean flakes.
Contamination Control Matched to Real Feedstock
Washing intensity, flotation, hot wash, and filtration can be adjusted for post-consumer film, agricultural film, and printed woven packaging.
Common Film Recycling Problems and Fixes
Problem
Rumtoo Solution
Thin film and bags bridge in hoppers or wrap around rotating parts.
Front-end sizing, wet shredding, and densifying are configured to keep conveying stable and reduce choke points before extrusion.
Problem
Rumtoo Solution
Mud, sand, paper, and organics stay attached after basic rinsing.
Higher-friction washing, sink-float separation, and optional hot washing are used where light rinsing alone will not reach cleanliness targets.
Problem
Rumtoo Solution
Wet film enters pelletizing with too much water and causes bubbles, odor, or unstable output.
A screw squeezer plus correctly sized drying and degassing stages reduce residual moisture and improve pellet consistency.
Problem
Rumtoo Solution
PP woven bags, jumbo bags, and printed BOPP structures behave differently from standard LDPE film.
Rumtoo selects different shredding, drying, and filtration routes depending on tensile strength, print load, and lamination complexity.
Machine and Process Reference
Key modules that determine moisture, density, and downstream pelletizing stability.
Squeezer-Densifier Between Washing and Pelletizing
For washed film, the squeezer is often the turning point between unstable wet flakes and a denser, more manageable feed for extrusion.
- Reduces residual moisture before thermal load increases
- Raises bulk density for steadier downstream handling
- Commonly used on PE film, agricultural film, and woven bag projects
Compactor and Filtration End of the Line
If the project ends in pellets, compaction, degassing, and filtration determine whether the line can handle printed film and maintain stable output.
- Improves feeding of low-density film into the screw
- Supports cleaner melt processing on mixed post-consumer feed
- Helps reduce downtime caused by unstable contamination load
Typical Feedstocks and Use Cases
Post-Consumer PE Film
LDPE and LLDPE shopping bags, supermarket film, and mixed collection film with paper, organics, and labels.
Agricultural Film
Mulch film, greenhouse film, and silage wrap carrying soil, fertilizer residue, and high moisture.
Stretch Wrap and Pallet Covers
Warehouse and logistics scrap where density is low but contamination is usually lighter and more predictable.
PP Woven Bags and Raffia
Cement sacks, feed bags, jumbo bags, and woven industrial packaging requiring stronger anti-wrapping preparation.
Printed BOPP and Packaging Film
Printed or laminated structures where adhesives, inks, and odor risk push the need for stronger washing and filtration.
In-House Film Reuse Projects
Factory edge trim, converting scrap, and clean post-industrial streams routed either to flake reuse or pelletizing.
Technical Scope and Reference Configurations
| Line Family | Typical Output | Final Moisture Target | Typical Process Route |
|---|---|---|---|
| RFL-500 | 300-500 kg/h | < 5% | Wet shred + friction wash + centrifugal / squeezer |
| RFL-1000 | 800-1,000 kg/h | < 3-5% | Wet shred + sink-float + squeezer + hot air |
| RFL-1500 | 1,200-1,500 kg/h | < 3% | Heavy-duty washing + squeezer + buffer silo |
| RFL-P | Pellet output option | Feed to extruder depends on line | Cutter-compactor / extrusion + degassing + filtration |
| Utilities | Project-specific | Depends on material | Water treatment, drying heat, and extraction sized by contamination |
Actual performance depends on feedstock mix, contamination level, target cleanliness, moisture requirement, and whether the final product is washed flakes or pellets.
Project Checklist Before RFQ

Feedstock Mix
List the share of LDPE, LLDPE, HDPE film, PP woven bags, raffia, BOPP, or laminated packaging in the project.
Contamination Profile
Describe soil, sand, paper, labels, ink load, organics, and whether the material is post-consumer, agricultural, or post-industrial.
Output Requirement
Clarify whether you need washed flakes, densified material, or finished pellets, plus your target moisture and cleanliness level.
Utilities and Layout
Confirm power supply, water loop or treatment plan, thermal drying options, and available footprint for tanks, silos, and pelletizing.
System-Level Comparison
| Decision Criteria | Basic Film Line | Rumtoo Integrated Line |
|---|---|---|
| Handling Low-Density Film | More surge feeding and wrapping risk | Front-end prep and densifying reduce instability |
| Drying Strategy | Single drying method only | Mechanical squeezing plus staged drying options |
| Printed / Dirty Material | Limited adaptation to ink and mud load | Washing intensity and pelletizing interface are configurable |
| Expansion Path | Harder to connect pelletizing later | Built to connect with downstream densifying or pelletizing modules |
| Project Customization | Generic configuration | Layout and utility design matched to feedstock and target output |
Frequently Asked Questions
Which materials can this line process?
Typical inputs include LDPE and LLDPE film, stretch wrap, shopping bags, agricultural film, and PP woven bags. Printed BOPP or laminated structures may also be possible, but they usually need stronger washing and more careful downstream filtration planning.
Do I need a squeezer, or is a centrifugal dryer enough?
For lightweight washed film, a centrifugal dryer alone often leaves too much residual water. A screw squeezer is usually preferred when the line must feed pelletizing stably or hit a lower final moisture target.
What final moisture can I expect after washing and drying?
For many film projects, the practical target after squeezing and drying is below about 3-5%, depending on feedstock, contamination level, and whether the next stage is storage, agglomeration, or pelletizing.
When is hot washing necessary for film recycling?
Hot washing is usually considered when the material carries heavy labels, oils, glue, food residue, or difficult printing contamination that cold friction washing cannot remove reliably.
What should I send before asking for a quotation?
Send material photos, the feedstock mix, contamination description, required kg/h, whether you want flakes or pellets, and any layout or utility constraints. Those inputs are the minimum needed for a practical proposal.
