This additive is particularly suitable in packaging for ultra-high temperature (UHT) liquid dairy products, as these types of products have a longer shelf life, making them more susceptible to light-induced oxidation due to ambient storage conditions.

This kind of layered packaging is common in dairy products because it keeps the liquid inside while keeping bacteria outside. This additive is particularly suitable in packaging for ultra-high temperature (UHT) liquid dairy products, as these types of products have a longer shelf life, making them more susceptible to light-induced oxidation due to ambient storage conditions. We present Adjusted EBITDA because we believe that it is a further supplemental measure of our performance and liquidity.
