How a Cutter Compactor Pelletizing Line Works
The core process logic is to turn unstable low-bulk-density film into a predictable melt and then into downstream-ready pellets.
1
Feed Washed Film or Raffia into the Compactor
The line starts with low-bulk-density PP PE film, woven bags, raffia, or similar soft scrap that would otherwise feed unevenly into a standard extruder.
2
Cut, Heat, and Densify Before Extrusion
Inside the cutter compactor, the material is reduced, pre-heated, and densified so the PP PE film pelletizing machine receives a more stable feed stream.
3
Degas and Filter the Melt
Moisture, ink volatiles, and contamination are removed through venting and filtration matched to the print load, washing quality, and pellet market requirement.
4
Pelletize for Reuse or Sale
The finished melt is cut by water-ring or strand pelletizing, then cooled, dried, and screened into reusable plastic film pellets for downstream production.
Why Choose a Rumtoo Film Compacting Pelletizing Line
Six models from 150 to 1,200 kg/h with integrated cutter-compactor, progressive screw design, and matched filtration for washed film recycling.
Integrated Cutter-Compactor Feed Prep
Film, raffia, and woven bags are cut, pre-heated, and densified inside the compactor (300–1,100 L) before entering the extruder — eliminating bridging and surging that plague direct-feed systems.
Scalable 6-Model Range
Six standard models (ML85–ML180) cover 150–1,200 kg/h. Choose the right compactor volume and extruder size for your film type, moisture level, and production target.
Effective Moisture & Volatile Removal
Single or double venting combined with the compactor pre-drying action handles residual moisture and ink volatiles from washed and printed film without separate pre-drying equipment.
Common Film Pelletizing Problems — and How Rumtoo Lines Address Them
Most film pelletizing failures come from feeding instability and moisture — not from extruder undersizing.
Problem
Fluffy washed film bridges, surges, and starves the extruder screw, causing uneven melt and pellet defects.
Rumtoo Solution
The integrated cutter-compactor cuts, pre-heats, and densifies film before the screw — delivering stable, consistent feed regardless of bulk density variation.
Problem
Residual moisture from washing causes bubbles, voids, and surface defects in finished pellets.
Rumtoo Solution
Compactor pre-drying plus atmospheric or vacuum venting on the extruder removes moisture before the die. No separate thermal dryer needed in most configurations.
Problem
Printed film releases ink volatiles that discolor pellets and create odor problems.
Rumtoo Solution
Enhanced venting zones extract ink volatiles during extrusion. Double venting configurations are available for heavily printed or laminated film.
Problem
Pellet quality varies between batches, making downstream use or resale unreliable.
Rumtoo Solution
Consistent compactor feed prep + matched filtration + water-ring or strand pelletizing produces repeatable pellet geometry, density, and melt quality batch after batch.
Equipment and Film Output Showcase
Film pelletizing buyers usually compare whether the line can tame fluffy washed film into a stable melt and a repeatable pellet stream.
Equipment View: Cutter Compactor and Extrusion Block
The decisive configuration is often not only the extruder size. It is how the cutter compactor, venting, filtration, and pelletizer work together on low-density film feedstock.
- Shows why compaction and extrusion must be engineered as one route
- Helps define venting strength for moisture and printed volatiles
- Improves line matching for raffia, woven bag, and mixed film streams
Material View: Stable Polyolefin Recycled Pellets
The line should convert unstable fluffy feed into pellets with predictable shape, density, and handling behavior for storage, reuse, or sale.
- Reduces feeding instability carried from washed film
- Supports more consistent water-ring or strand cutting
- Frames pellet quality around downstream reuse instead of only output rate

Watch how washed PE/PP film is densified, extruded, filtered, and pelletized into high-quality recycled pellets.
Applications
Washed PE/PP Film Recycling
Pelletize agricultural film, stretch film, shopping bags, and post-consumer washed film with better feeding stability.
Raffia and Woven Bag Recovery
Handle woven sacks, jumbo bag scrap, and raffia trims that need densifying before the melt section.
Low-Bulk-Density Polyolefin Reuse
Create stable reuse pellets from fluffy film scrap where direct screw feeding would surge or bridge.

Frequently Asked Questions About Film Compacting Pelletizing Lines
What is the difference between a film pelletizing line and a hard plastic pelletizing line?
Film lines include a cutter-compactor to densify low-bulk-density film before extrusion. Hard plastic lines use force-feeding for dense rigid flakes. The compactor is the key differentiator — without it, fluffy film cannot be fed stably into the extruder.
Does the line need a separate dryer before the compactor?
In most cases, no. The cutter-compactor pre-heats and partially dries the film through friction and agitation. Combined with the extruder venting system, this handles typical residual moisture from washed film (5–15%). For extremely wet material, a mechanical squeezer upstream may be recommended.
Can this line handle printed and laminated film?
Yes. Printed and laminated film releases ink volatiles during extrusion. The line can be configured with enhanced or double venting to extract these gases. Pellet color and odor depend on print load — contact Rumtoo with your specific film type for recommendations.
How do I choose between the ML85 and ML180 models?
Selection depends on target throughput, film type, moisture level, and compactor volume needed. The ML85 (300 L compactor, 150–200 kg/h) suits smaller operations; the ML180 (1,100 L compactor, 900–1,200 kg/h) serves large-scale production. Contact Rumtoo with your material details.
