Avient Unveils Light-blocking Additives with Low TiO₂ and Inorganic Content

Avient has announced the launch of ColorMatrix™ Lactra™ Four, ColorMatrix™ Lactra™ One, and ColorMatrix™ Lactra™ Zero additives. This new product range offers low total inorganic and TiO₂ content light-blocking solutions for PET dairy and dairy-alternative packaging.

Reducing TiO₂ to Meet Future Regulations

Food and beverage brand owners are aware of current French tariffs and potential future tariffs that may limit TiO₂ content in packaging. As a result, brand owners in the EU, Asia, and LATAM are proactively reducing TiO₂ and total inorganic content in their packaging to less than 4 percent, with an eye toward an expected future reduction to less than 1 percent.

The new range of Lactra™ additives helps to streamline this process, as they process well at similar conditions to virgin PET. These next-generation light blocking solutions also include:

• REACH compliance
• EU food contact approval
• Full light blocking (>99.8% up to 700nm) performance even in thin wall sections

To help packaging customers further their recyclability and lightweighting goals, Avient developed this technology for mono-layer PET, one of the most widely recycled packaging materials. Lactra Four, One, and Zero offer light blocking up to 99.9 percent with total inorganic content of less than 4 percent and TiO₂ content between 4 and zero percent. Additional benefits include improved performance in thin wall sections, superior whiteness, and better processability with virgin PET grades and rPET.
