Cutter Compactor Pelletizing Machine

Need a plastic film recycling machine for recycling soft plastic like LDPE/LLDPE/HDPE film, bags, and post-industrial scrap? The Rumtoo ML Series compactor pelletizer densifies loose film in a cutter-compactor, then extrudes, filters, and pelletizes it into uniform, high-value granules.

Why Soft Film Can’t Go Straight Into a Normal Extruder

Thin film and bags are “fluffy” and light. In a standard hopper + screw, they don’t feed like rigid flakes. That’s why many film recycling lines suffer from unstable output, overheating, and inconsistent pellet quality.

Bridging (Arching) & Hopper Blocking

Soft film tends to bridge at the hopper throat. Material stops flowing, then suddenly collapses, causing surge feeding and poor melt stability.

Low Bulk Density = “No Bite” on the Screw

Film can slip instead of being conveyed. The screw starves, output drops, and temperature control becomes difficult.

Uneven Melting & More Contamination Risk

When feeding fluctuates, melting and degassing fluctuate. This increases gels, black specks, and odor—especially with printed film.

The “Cutter Compactor + Extruder” Solution

Stable Feeding for Thin Film

The cutter-compactor chops, mixes, and densifies film into a heavy, free-flowing feedstock—then force-feeds it to the extruder. This prevents bridging and keeps output stable.

Cleaner Melt With Vacuum Degassing

Built-in degassing removes moisture, inks, and volatiles. You get cleaner pellets and fewer defects when processing printed film and mixed soft scrap.

Non-Stop Filtration

With a hydraulic screen changer, you can change screens without stopping the line—reducing downtime and protecting pellet quality.

Ideal Applications

Designed for recycling soft plastic, the ML Series cutter compactor pelletizer turns common film waste streams into high-value granules.

Post-Industrial Film

Perfect for clean factory scraps, edge trims, and off-cuts of LDPE, LLDPE, and HDPE stretch films.

Washed Agricultural Film

Handles greenhouse films and mulch films that have been washed and squeezed, tolerating residual moisture.

PP Woven Bags

Efficiently densifies and pelletizes crushed raffia bags, cement bags, and jumbo bags (FIBCs).

Crushed Regrinds

Also suitable for pre-crushed rigid plastics like HDPE bottles, crates, and pipe flakes mixed with films.

Our 4-Step Process

1

Cutter-Compactor Densifying

Film is conveyed into the cutter-compactor, where it is cut, mixed, and densified into a stable, free-flowing feedstock for extrusion.

2

Extrusion & Degassing

The densified material is forced into the single-screw extruder, then melted, plasticized, and vacuum degassed.

3

Filtration & Pelletizing

Molten plastic is filtered for impurities and then cut into uniform pellets by a water-ring pelletizing system.

4

Drying & Collection

Pellets are rapidly dewatered and sent to a silo for cooling, bagging, and storage.

From tangled film to uniform pellets. Watch how cutter-compactor densifying solves “film feeding” problems and keeps output stable.

Frequently Asked Questions

Why can’t soft plastic film feed into a normal extruder?
Because film is fluffy and has very low bulk density. It easily bridges in the hopper and slips on the screw, so the extruder starves and output becomes unstable. A cutter-compactor densifies the film and force-feeds it into the extruder for stable melting and pelletizing.
What is a cutter compactor pelletizer (compactor pelletizer)?
A compactor pelletizer combines a cutter-compactor (densifying chamber) with an extruder. The cutter-compactor chops, mixes, and compacts thin film and bags into a dense, free-flowing feedstock, enabling stable extrusion, degassing, filtration, and pelletizing.
What materials can your compactor pelletizer process?
Typical applications include LDPE/LLDPE/HDPE film, stretch film, shopping bags, agricultural film (washed and squeezed), and PP woven bags. Share your material photos and contamination level for a recommended configuration.
What is the maximum moisture content for washed film?
For the best performance, we recommend feeding film with moisture below 3%. Up to 5% moisture may be possible depending on the material and line setup (venting, vacuum level, and throughput).
How does this machine compare to a twin-screw model?
A single-screw system with cutter-compactor feeding is the typical choice for recycling soft plastic film because it’s efficient, durable, and cost-effective. Twin-screw extruders are usually used for compounding (mixing polymers, adding fillers/additives), which is a different application.
What is your warranty and after-sales support policy?
The ML Series comes with a comprehensive 1-year limited warranty on major non-wear components. We offer comprehensive after-sales support including spare parts, remote technical assistance, and on-site service options. For full details, please visit our comprehensive FAQ & Support Center.
