Aldi and Arla Implement Smart Packaging with UV Tags

Aldi and Arla are collaborating to enhance recycling data collection through the introduction of smart packaging technology. This project employs Polytag 's UV tags, printed with Sun Chemical 's specially developed food-safe fluorescent ink, on wrap-around labels for milk bottles. The ink, which has passed rigorous safety and recycling testing, is applied using standard printing methods. This ensures a cost-effective and easy integration into existing production lines without affecting speed. The current iteration, unlike the 2023 trial that used pressure-sensitive labels, uses wrap-around labels for added durability and coverage. When packaging with these tags enters the recycling stream, Polytag's Plastic Detection Units at Materials Recovery Facilities (MRFs) capture barcode-level data in real time. This allows companies to gather comprehensive insights into the recycling lifecycle of their products. Luke Emery , Aldi UK's plastics and packaging director, emphasized the ...
