Water reduces molecular weight (MW) during post-consumed PET recycling through a hydrolysis reaction. Moisture contamination should be below 0.02% to avoid the MW reduction. Most water content comes from the flake washing process but can be reduced substantially by proper drying . 4.1.3. Coloring contaminants
