PolyOne today announced the launch of ColorMatrix™ Amosorb™ 4020G, a non-nylon-based low-fog oxygen scavenger for rigid PET packaging
It is understood that this new 4020G grade can achieve up to 50% lower haze compared to the original grade, reducing the impact on the PET circulating flow, while maintaining the same reliable ROS scavenging performance
Commonly used in food and beverage packaging, PET offers design flexibility and high permeability for easy multiple recycling
ColorMatrix Amosorb 4020G not only helps reduce haze, but also reduces the impact on recycled PET (rPET), which can reduce yellowing by 50% during mechanical recycling
To support the development of a circular economy, governments are enacting legislation to increase the content of recyclable materials in single-use packaging
As the proportion of rPET in packaging continues to increase, brands need to ensure that the oxygen scavengers used in PET bottles remain effective
PolyOne testing has shown that ColorMatrix Amosorb 4020G is one of the strongest oxygen scavengers for rigid PET containers, with negligible effect on the rPET grades tested, while other comparable materials are almost lost at rPET levels as low as 20% All oxygen scavenger capabilities
ColorMatrix Amosorb 4020G has the appropriate regulatory approvals, PolyOne said
