In the field of plastic recycling, in order to pursue higher quality recycled materials, PET recycled materials need to be upgraded to a level equivalent to the performance of raw PET. Among various plastics, polyethylene terephthalate (PET) is widely used in the packaging field, especially standing out in bottled beverage packaging. However, to improve the performance of PET recycled materials to a level comparable to that of native PET, advanced technology is required, which is PET IV viscosity increasing machine.

 IV value is a key parameter for measuring the molecular mass of PET, which reflects the chain length of the polymer and is directly related to mechanical properties such as strength, toughness, and processability. Native PET typically has a high IV value, thus possessing excellent durability and transparency. However, during the recycling process, the IV value of PET fragments usually decreases due to thermal and mechanical degradation in the previous processing.
The IV increasing machine is used to increase the viscosity of recycled particles, allowing the recycled PET material to be reintegrated into high-quality products.

The PET recycled flakes IV increasing machine is a specialized recycling machine used to increase the molecular mass of PET recycled flakes. This technology typically uses solid-state polymerization (SSP) process, in which PET recycled flakes are heated to below its melting point in a controlled atmosphere (usually nitrogen or vacuum) to promote the extension or recombination of polymer chains without melting the flakes.
This process helps to repair the damage to polymer chains accumulated in the early processing stages by driving out volatile byproducts and achieving chain reactions that rebuild molecular mass. Therefore, recycled PET flakes have higher IV, better crystallinity, and better mechanical properties.

1. Improve product quality
Increasing PET recycled flakes IV can improve the mechanical strength, thermal stability, and transparency of recycled PET, making it suitable for demanding applications such as food grade bottles and industrial packaging.
2. Environmental impact
By improving the quality of PET recycled sheets, the dependence on raw PET has been reduced, fossil resources have been saved, and greenhouse gas emissions related to new plastic production have been lowered.
3. Higher economic value
Recycled PET materials with higher IV can obtain better market prices and open up more profitable markets, such as polyester fiber manufacturing and injection molding, thereby increasing the profitability of recycling facilities.

Driven by sustainable development and regulatory pressures, the PET recycling industry is rapidly growing. Integrating the IV increasing and PET crushing, cleaning, and granulation production lines into one line to reduce the cost of PET raw materials, improve the quality of recycled PET materials, and accelerate the transition to a circular plastic economy.
The PET flakes IV increasing machine is a key advancement in the PET recycling industry. By restoring degraded polymers to near their original quality, it enables manufacturers to produce sustainable plastic products without compromising performance. With the surge in global demand for recycled PET, investing in IV increasing technology is not only a wise move, but also crucial for building a greener and more circular future.
