I am Otto, learning about pigments. As a benchmark in the pigment industry, Lanxess has always been in a leading position. Today, I will learn about the application of Lanxess Bayferrox® and Colortherm® series in packaging. If there are any errors, please help me correct them.
 
Bayferrox® and Colortherm® series pigments have a balanced cost-effectiveness, so compared to organic pigments, they can ensure high-quality coloring of various natural tones for plastic packaging and films, and reduce production costs. Lanxess' iron oxide can be used for coloring packaging that comes into contact with food.
 
In addition, classifying black plastics based on polymer categories is a key challenge in the mechanical recycling process. Bayferrox® 303T is a unique detectable black pigment. Compared with carbon black, its infrared reflectivity can reach up to 20%, so black plastics can be reliably distinguished through near-infrared detection.
