Processable Film Materials & Waste Types
This innovative system is designed to handle a diverse range of plastic materials.
Films
PP, PE, HDPE, LDPE, and LLDPE film scrap.
Packaging
PA66, PC, PET, OPP, and BOPET packaging scrap.
Fibers and Others
ABS, raffia, silk, yarn, and foamed PE material streams.
How the Cutter Compactor Pelletizing System Works
1. Feeding
A belt conveyor, with an optional metal detector, transports plastic scraps into the compactor.
2. Compaction
Rotating blades cut, compact, and soften the material using frictional heat for stable feeding into the extruder.
3. Extrusion
A single-screw extruder gently melts the material, while double-zone vacuum degassing removes volatiles.
4. Pelletizing
Water-ring die-face cutting technology precisely cuts the extruded material into uniform pellets.
5. Drying
An advanced dewatering sieve and centrifugal system efficiently dry the pellets while reducing energy demand.

Cutter Compactor vs. Traditional Two-Step Pelletizing
Why integrate cutting, densifying, and extrusion into one continuous line?
| Comparison Factor | Cutter Compactor Line This System (Integrated Single-Step) | Traditional Two-Step System Separate Granulator + Extruder |
|---|---|---|
| Process Workflow | Continuous single step: Integrated cutting, frictional compaction & extrusion in one closed line | Disconnected two steps: Offline granulating/shredding followed by manual or batch conveying |
| Feeding & Bridging | Direct tangential feed: Warm, densified film drops into screw with zero bridging or wrapping | Frequent bridging & wrapping: Fluffy film jams feed throat; requires manual pushing |
| Footprint & Labor | Compact footprint: 1 single operator manages the entire automated line; zero buffer silos | Large footprint: Multiple standalone machines & intermediate bins; requires 2–3 operators |
| Feedstock Versatility | Excels on difficult scrap: Stretch film, agricultural film, raffia, woven big bags & light flakes | Limited to rigid regrind: Struggles with low-bulk-density, lightweight, or elastic thin films |
| Thermal Efficiency | Utilizes frictional pre-heating: Compactor blade friction pre-heats melt, cutting heating energy | Cold feeding: 100% reliant on external barrel heaters; unstable melt pressure |
| Total Ownership Cost (TCO) | Rapid ROI (<12 months): Higher initial machine cost offset by 30%+ labor & uptime savings | Lower initial price: But significantly higher ongoing labor, handling costs & downtime |
Process Recommendation: For clean, dense rigid regrind, a conventional pelletizer is sufficient. For fluffy, lightweight, or printed film waste, the integrated cutter compactor pays for itself quickly through uninterrupted throughput and labor savings.

Frequently Asked Questions
The main advantage is its ability to handle lightweight, fluffy materials like films and fibers in a single, integrated step. The compactor pre-densifies and pre-heats the material, which allows for a very stable and efficient feeding process into the extruder.
For most soft materials like films and light scraps, a separate shredder is not needed. The cutter compactor itself performs the initial size reduction and densification. However, for very large or thick materials, a pre-shredder might be recommended to optimize throughput.
This is a crucial feature for processing printed films or materials with some moisture. It effectively removes volatiles like ink gases and residual moisture from the molten plastic in the extruder. This results in higher-quality, bubble-free pellets.
It is designed for soft and lightweight plastics such as PP/PE films, bags, packaging scrap, raffia, woven bags, fibers, and similar industrial scrap streams.
Typical models cover about 180–1,500 kg/h depending on material condition, screw size, and motor configuration. Exact capacity is confirmed after reviewing your feedstock.
