Track record

Recycled PET bottle flakes are created from waste beverage bottles by measures of sorting/ crushing/ washing and drying and so on. , therefore recycled PET bottles flakes can be developed at any area the place beverage intake can be occurred. As the principal industry of recycled PET bottle flakes importing, there are more than ten-13 million tons PET bottle flakes imported into China every single yr.
In calendar year of 2017, environmental rules in China gets more and more strict, waste plastics are completely forbidden to import into China, as portion of waste plastics, recycled PET neither can be imported in any forms of bottles bales or flakes Pursuing the Chinese environmental rules, recycled plastics can only be imported in the kind of granules/chips, as a result, it is necessary to re-pelletize the recycled PET bottles flakes for PET bottle flakes recyclers.

CZPTly forbidden to import into China, as component of squander plastics, recycled PET neither can be imported in any varieties of bottles bales or flakes Adhering to the Chinese environmental regulations, recycled plastics can only be imported in the form of granules/chips, consequently, it is required to re-pelletize the recycled PET bottles flakes for PET bottle flakes recyclers.

Processing considerations

  • Keep away from hydrolyzing throughout PET bottles flakes re-pelletizing procedure
  • Massive displacement ventilating unit needed to understand minimum IV value lowering
  • Steer clear of or reduce yellowing impact in the course of re-pelletizing approach
  • CZPT pelletizing approach requested to reduce the labor load and understand stable substantial output.

Recycled PET bottle flakes re-pelletizing flowchart from ACERETECH

Attributes of PET bottle flakes recycling and pelletizing method from ACERETECH

  • Adequate pre-drying time is necessary just before the bottle flakes enter into re-pelletizing phase, ACERETECH adopts either venting kind compactor or lifting type drying hopper to pre-dry the flakes and eliminate the moisture from flakes, to avoid PET hydrolyzing throughout the re-pelletizing process


  • Merge the functions of modular made processing segment and effectively degassing efficiency construction from twin screw extruder and automated 3-amount roots variety vacuum pump established, limit vacuum degassing force can be assured reaching -.1MPa, to take away the volatiles from PET melts maximumly via degassing device, so as to promise small IV benefit minimizing


  • Optimized process steps and specialized made processing segment of twin screw extruder, make the PET flakes repeatedly and effectively  transforming from sound condition into liquid condition, to keep away from yellowing impact which could be happened because of lifeless angle or local higher temperature
  • Strands pelletizing device is the typical PET pelletizing technique, the strands which come out from extruder’s die part, will be manually hauled into the water trough to amazing, then, drinking water taken out by way of the air knife device, cut by the rotary blades of pelletizer and form the granules/chips. This strands pelletizing way requests more labor and experienced operation behavior, is suitable to the potential request underneath 600kg/h for PET flakes re-pelletizing
  • But relating to substantial potential PET pelletizing task, strands pelletizing way is not appropriate, automated and dependable underwater pelletizing method is required to guarantee large output and automation efficiency.
