New additives of Avient improves oxygen scavenging for 100% rPET content

Source：Adsale Plastics Network Date ：2021-05-11 Editor ：JK

Avient has launched ColorMatrix Amosorb 4020R, a non-nylon-containing oxygen scavenger additive specifically formulated to enable the use of up to 100% rPET content. This new additive joins the robust portfolio of ColorMatrix additives that enable improved recycling for plastic packaging.

Amosorb 4020R delivers full, consistent oxygen scavenging performance with 25%, 50%, and even 100% 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 different rPET grades to help brand owners achieve their sustainability targets.

ColorMatrix Amosorb 4020R high rPET content oxygen scavenger additive.

PET packaging can be easily recycled, yet plastic packaging waste in landfills and oceans is increasing worldwide. In response, countries are putting forth legislation that specifies minimum recycled content for packaging. Brand owners themselves are committing to increased recycled content beyond these regulations. As a result, the demand for high quality rPET packaging has been great.

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