The Ultimate Challenge in PET Recycling: How to Remove Glue and PVC Effectively
In the rPET (recycled polyethylene terephthalate) industry, the market price of your final flakes is directly determined by their purity. Two of the biggest headaches for recyclers are residual glue from labels and PVC contamination. Even a tiny amount of PVC can ruin an entire batch of PET during extrusion.
As a veteran manufacturer, LAIZHOU KEDA CHEMICAL MACHINERY CO., LTD. has mastered the technology to eliminate these contaminants seamlessly.
The KEDA 3-Step High-Purity Process
1.
Mechanical Label Separation: Before crushing, our high-efficiency label remover strips off over 95% of plastic and paper labels dry, preventing them from mixing with the PET flakes.
2.
3.
Thermo-Chemical Hot Washing: Our specially designed hot washing tanks utilize precise temperature controls and eco-friendly chemical ratios to completely dissolve stubborn industrial adhesives and glues.
4.
5.
Advanced Density Separation (Sink-Float): Utilizing the density difference between PET ($>1.3g/cm^3$) and caps/PP/PE ($<1g/cm^3$), our rinsing system automatically floats away impurities, leaving pure PET flakes at the bottom.
6.
By integrating these modules, LAIZHOU KEDA's PET Bottle Flake Washing Line consistently delivers flakes with less than 20ppm of PVC and minimal moisture, perfect for high-end fiber or sheet production.
