Full Light-Blocker (DairyArmor)

The ColorWay Full Light-Blocker (DairyArmor), provided in solid masterbatch form, constitutes an advanced light-blocking technology designed to preserve the quality of liquid dairy contents when incorporated into monolayer PET bottles.

ColorWay Full Light-Blocker (DairyArmor)

ColorWay Full Light-Blocker (DairyArmor) is a highly effective additive for packaging ultra-high temperature (UHT) liquid dairy products, protecting them from oxidative degradation caused by light exposure during extended shelf life. It ensures prolonged ambient shelf life by mitigating light's impact on product quality. DairyArmor provides light-blocking effectiveness similar to multi-layer or Tetra Pak packaging and supports diverse bottle designs without affecting production efficiency or causing delamination. It integrates seamlessly with oxygen barriers, allowing for lightweight, customizable protection using standard PET pellets and existing single-layer injection molding equipment, eliminating the need for additional investments.
