Avient introduces oxygen scavenging additives to promote PET recyclability

Avient Corporation has announced the launch of the first grade in its new ColorMatrix Amosorb Oxyloop portfolio of oxygen scavengers: ColorMatrix Amosorb Oxyloop-1.

The cutting-edge oxygen scavenging additive is formulated to enhance the recycling capabilities of polyethylene terephthalate (PET) packaging, providing brands with extended product shelf life, meet sustainability goals, and contribute to a more circular economy.

Avient’s Oxyloop-1 grade has earned the endorsement of the European Platform for Bottle Packaging (EPBP) for bottle-to-bottle recyclability for the coloured recycled stream. The non-nylon-based product is also compatible with recycled polyethylene terephthalate (rPET), meaning brands can incorporate higher levels of recycled material into their packaging.

One of the standout features of ColorMatrix Amosorb Oxyloop-1 is that it can deliver oxygen scavenging performance, even with up to 100% rPET content, so that packing applications for products like juices, vitamin drinks, ready-to-drink (RTD) teas, and certain dairy products maintain their freshness and shelf life. 

Offering outstanding bottle clarity, this additive can be used in monolayer or multi-layer bottle structures as well as transparent applications that require a high-quality solution to support recyclability. The absence of nylon in this formulation can also minimise yellowing in the transparent recycling stream, preserving the aesthetic appeal of transparent bottle applications.

“We are thrilled to introduce the ColorMatrix Amosorb Oxyloop-1 grade to the market,” said Dr Antonello Decortes, global product platform manager at Avient Corporation. “This new Oxyloop technology represents a significant step forward in our commitment to sustainability and circularity. By enhancing the recyclability of PET packaging, we are helping brand owners and converters achieve their sustainability goals and reduce their environmental impact.”

ColorMatrix Amosorb Oxyloop-1 additive meets direct food contact regulatory requirements in major markets.
