Avient announced the launch of ColorMatrix™ Lactra™ Four, One, and Zero additives. This new product range offers low total inorganic and TiO2 content light-blocking solutions for PET dairy and dairy-alternative packaging.
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.
NOTE TO EDITORS: Dairy and dairy-alternative products are susceptible to light-induced oxidation that reduces product nutritional value and can cause off-flavors. In PET packaging, specialized light blocking additives are regularly used to stop visible-light induced contents from degrading under commercially relevant storage conditions, helping to prolong the shelf life of dairy packaged products such as ultra-high temperature (UHT) milk. These new additives are an expansion of this technology.
