white-milk-bottleAvient 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.
