In the latest phase of a collaboration that dates back to 2023, the brands are hoping to gain a better understanding of how milk packaging moves through the recycling system.
UV-tagged labels (printed by Saica Flex and using Sun Chemical’s food-safe fluorescent ink) are applied to Arla’s milk bottles at its Oakthorpe site. The labels facilitate real-time tracking of packaging through the system.
In the initial trial pressure-sensitive labels were used, but this time wrap-around labels were chosen in a bid to boost durability and coverage.
