vient has developed a non-nylon-containing oxygen scavenger additive that has been specifically formulated to enable the use of up to 100 percent recycled PET content. As part of the company’s portfolio of ColorMatrix additives, the additive, marketed under the brand name ColorMatrix Amosorb 4020R, improves the improves the aesthetics of recycled packaging in terms of haze and colour. It also reduces the yellowing effect that may occur during recycling.
The additive, said Avient, is compatible with many different rPET grades.
Because PET packaging can be easily recycled, and because countries are putting legislation in place that specifies minimum recycled content for packaging, demand for high quality rPET packaging is huge and it is growing.
During recycling, however, aesthetics and oxygen scavenging performance can be affected. 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.
