PET Bottle Flake Pelletizing Line (High Viscosity)
The increasing demand for sustainable solutions has led to the growth of PET bottle recycling plants. To expand the utility of PET flakes, our advanced pelletizer transforms clean PET flakes into versatile plastic pellets, ideal for injection moulding, sheet production, and more.
Advanced Technology for Superior Pellets
- Advanced Moisture Removal
A compactor removes moisture, crucially maintaining the intrinsic viscosity (IV) of the PET material.
- Efficient Single Screw Extrusion
A high-quality nitride steel screw ensures optimal compacting, melting, and homogenisation of PET flakes.
- High-Purity Vacuum Degassing
Removes low molecular weight materials and residual moisture to ensure the purity of the final product.
- Uniform Underwater Pelletizing
Transforms the melted PET into high-quality, uniform granules, ensuring optimal shape and consistency.
Working Principle
Our PET pelletizing line follows a precise, multi-stage process to convert PET flakes into high-grade pellets:
- 1. Feeding and Moisture Removal
An automated system controls feeding speed, while a compactor removes moisture from the flakes.
- 2. Single Screw Extrusion
The PET material undergoes compacting, melting, and homogenisation in the high-performance extruder.
- 3. Barrel Processing
The nitride steel barrel heats the plastic with precise temperature control for consistent melting.
- 4. Vacuum Degassing
This step removes low molecular weight materials and any residual moisture from the melted PET.
- 5. Melt Filtration
A specific filtration technology is employed to ensure the purity of the melted plastic before pelletizing.
- 6. Pelletizing
The underwater pelletising system transforms the melted PET flakes into uniform, high-quality granules.
- 7. Drying and Bagging
Pellets are dried via a vibration sieve and centrifugal dryer, then bagged for distribution.

Frequently Asked Questions
Pelletizing transforms PET flakes into uniform, dense pellets. This expands their utility far beyond flakes, making them suitable for high-end applications like injection moulding and sheet production, which require consistent material properties.
Moisture can degrade PET during the melting process, significantly reducing its Intrinsic Viscosity (IV). Lower IV results in brittle, poor-quality final products. Our system’s moisture removal and degassing steps are crucial for maintaining high IV and producing top-grade pellets.
Yes, the system is designed with flexibility in mind. The melt filtration stage can be equipped with different filtration technologies depending on the contamination level of the input flakes and the required purity of the final pellets.
