ColorMatrix™ Lactra™ LX

ColorMatrix™ Lactra™ LX by Avient (Formerly PolyOne) is a bright white, solid masterbatch and light blocking additive. It provides high-performance light blocking technology and protection for liquid dairy products in monolayer polyethylene (PET) bottles. It protects contents from visible light and extends shelf life.

• Its core functionality lies in providing 100% visible light blocking which significantly reduces light-induced oxidation.
• It prevents degradation caused by light exposure particularly during long ambient storage.
• It enables versatile container designs and shapes for easier pouring and product differentiation.
• It is suitable for re-sealable containers or containers that are stored flat after opening.
• It offers package light weighting with no reduction in light blocking performance.
• It reduces overall system cost compared to other rigid packaging options.
• It helps preserve essential nutrients like vitamins A, B2 (riboflavin), D and amino acids.
• It also prevents oxidation of milk fats which can result in off-flavors.
• It enhances the user-friendliness of UHT dairy packaging by enabling the use of a single-layer PET bottle that provides the same visible light blocking as multilayer HDPE or paperboard packaging.
• ColorMatrix™ Lactra™ LX minimizes light-induced oxidation and helps preserve both the products nutritional properties and taste even during long periods of ambient storage typical of UHT dairy products.
