PET Bottle Recycling Machine | Turnkey PET Bottle Washing & Pelletizing Recycling Line
From waste bottles to recycled pellets – a one-stop PET bottle recycling solution.
Whether you need a complete PET bottle recycling production line or equipment upgrade for a specific link, we can provide a one-stop solution for the entire chain from bottle → bottle flakes → recycled particles.
  PET Bottle Washing LineEffectively removes labels, dirt, glue, and other contaminants from compressed bottle bales. Produces high-quality rPET flakes suitable for further processing. |
 PET Pelletizing LineMelts and extrudes high-purity PET flakes into rPET pellets. Widely used in high-end applications such as preform injection molding and sheet extrusion. |
 Plastic Bottle CrusherEfficiently crushes bottles into smaller pieces. Ideal for loose bottle recycling and entry-level recovery operations. |
OUR ADVANTAGES
As a specialized provider of complete solutions for plastic recycling—including washing, pelletizing, and crushing systems—we have:

Standard Configuration Overview of PET Flake Pelletizing Line
If your washed PET flakes require further value-added processing, they can be upgraded into high-quality recycled PET pellets through our purpose-designed PET Melt Pelletizing Line.
The complete process includes:
Conveying → Crystallization & Drying → Melting & Filtration → Strand Pelletizing → Pneumatic Conveying & Packaging
This fully integrated system enables a true closed-loop recycling process, helping manufacturers turn post-consumer PET into high-grade raw materials for new applications.
| Module | Function Summary | Key Highlights |
|---|---|---|
| Crystallizing & Drying Unit | Pre-crystallizes and thoroughly dries PET flakes | Twin-tower dehumidifying system; final moisture content < 0.5% to prevent hydrolysis during melting |
| Melt Extrusion System | Melts flakes and removes impurities via filtration | Twin-screw extruder with dual-station screen changer; ensures stable throughput and high filtration precision |
| Strand Pelletizing Unit | Cools and cuts the molten PET into pellets | Water cooling trough with air knife drying; produces uniform, burr-free pellets suitable for downstream processing |
| Cooling & Conveying System | Lowers the temperature of pellets and conveys them automatically | Integrated dedusting system ensures surface cleanliness meets export-grade requirements |
| Storage Silo & Packaging | Weighs, bags, and seals the finished pellets | Supports automatic batch packaging and real-time production monitoring for streamlined logistics |
Optional Upgrade Modules
| Module | Function |
|---|---|
| Solid-State Polycondensation (SSP) System | Enhances the Intrinsic Viscosity (IV) of flakes or pellets, enabling higher-end applications |
| Automated Intelligent Control System | Provides visualized monitoring and one-click adjustment of key processing parameters across modules |
| Melt Filtration System | Advanced impurity control to meet different quality standards of downstream products |
| Exhaust Gas Purification & Energy Recovery System | Purifies volatile gases generated during melting and recycles thermal energy for eco-friendly production |
