Barrier and Scavenger Additives

Barrier and scavenger additives play an important role in protecting and preserving PET packaged goods with a longer shelf life. They do this in two ways: by reducing acetaldehyde levels and by scavenging oxygen, to ensure that original content quality is maintained.

Acetaldehyde, which naturally occurs as a by-product of PET processing, can adversely affect the taste of packaged products. Effective AA scavenging technologies control AA levels without affecting container aesthetics or recyclability.

Oxygen scavengers (AA) also help reduce the risk of inferior product quality due to oxygen ingress and can be tailored to suit shelf life requirements. Oxygen scavengers are easy to use, keep containers clear, and are guaranteed to perform at a high level when used as recommended.

ColorMatrix™ AAzure™ Acetaldehyde Control Technology for PET

Reduce carbon emissions and preform AA while minimizing the risk of off-taste in bottle contents.

ColorMatrix™ Amosorb™ 4020G Low-Haze

Create an active barrier against oxygen ingress to help you enhance product protection and extend shelf life.

ColorMatrix™ Amosorb™ 4020R rPET Booster

Specifically formulated for use with recycled PET (rPET), this solution delivers full oxygen scavenging with up to 100% rPET content.

ColorMatrix™ Amosorb™ Oxygen Scavenger for PET

Control shelf life and reduce the risk of content degradation by incorporating our oxygen barrier solutions.

ColorMatrix™ Amosorb™ SolO₂ Co₂ Barrier and Oxygen Scavenger for PET

Active oxygen scavenging performance and a passive O₂/CO₂ barrier provide the ultimate protection combo for non-carbonated products and carbonated beverages.

ColorMatrix™ Capture™ Oxygen Scavenger

ColorMatrix Capture Oxygen Scavenger works by scavenging oxygen in both the bottle headspace and that passes through the bottle wall, helping enhance product protection and extend the shelf life of oxygen-sensitive beverages.
