New Additive for Recycled PET Improves Oxygen Scavenging at 100 Percent rPET Content


Avient has launched ColorMatrix™ Amosorb™ 4020R, a non-nylon-containing oxygen scavenger additive specifically formulated to enable the use of up to 100 percent recycled PET (rPET) content. This new additive enables improved recycling for plastic packaging.

Amosorb 4020R delivers full, consistent oxygen scavenging performance with even 100 percent rPET content. This new solution also improves the aesthetics of recycled packaging in terms of haze and color, including a reduction in the yellowing effect that may occur during recycling. In addition, the additive is compatible with many different rPET grades to help brand owners achieve their sustainability targets.

During recycling, aesthetics and oxygen scavenging performance can be affected. ColorMatrix Amosorb 4020R has been formulated to address this performance issue, and is the latest in a portfolio of solutions Avient has developed to enable high-quality recycled packaging.
