Aldi and Arla expanded their collaboration with Polytag to track milk bottles through the recycling process using UV-tagging technology. The project applies UV-tagged wrap-around labels to Arla milk bottles produced at its Oakthorpe site, helping the companies better understand how the packaging moves through recycling streams.
The labels use food-safe fluorescent ink and can be detected by Polytag units installed at Materials Recovery Facilities. These units capture barcode-level data in real time, with participating companies able to access the information through a dashboard. The latest trial uses wrap-around labels instead of the pressure-sensitive labels tested previously to improve durability and coverage.
For Aldi and Arla, the project provides more detailed visibility into packaging after the point of sale. The initiative supports data-based packaging decisions and reflects broader efforts to improve traceability and circularity across recycling systems.

What's Driving This Trend
- Invisible Packaging Traceability
- UV-readable identifiers embedded into everyday packaging create new data layers for post-consumer tracking, enabling brands to measure recycling outcomes with greater precision.
- Real-time Recycling Data
- Live capture of package-level movement through recovery facilities opens opportunities for analytics platforms that connect retail, manufacturing, and waste management systems.
- Durable Smart Labels
- Wrap-around labels with fluorescent marking technology represent a shift toward packaging components designed to survive handling, sorting, and recycling conditions while preserving scannability.
Who This Affects Most
- Sustainable Packaging
- Packaging suppliers can explore material and label formats that combine food safety, durability, and digital traceability for circular economy applications.
- Waste Management
- Recycling operators gain value from sensor-based infrastructure that transforms sorting facilities into data-generating hubs for brand and retailer reporting.
- Dairy Products
- Milk producers are positioned to use traceable bottle systems as a way to validate sustainability claims and refine packaging decisions across high-volume product lines.
