This collaboration combines Polytag's cutting-edge detection technology and expertise, Saica Flex's high-quality packaging production, and Paragon Inks specialist UV inks. The collaboration is already having tangible impact, with labels produced for Waitrose milk cartons now in-market and actively generating verified, reliable recycling data.
A product built for scalability and seamless integration
The labels carry invisible UV tags, printed with Paragon's inks products. Once they enter the recycling stream, Polytag's detection systems scan the labels and capture detailed, item-level data. Using this data, recyclers can track in real time which products enter recycling, measure recovery rates, and demonstrate compliance with regulations such as Extended Producer Responsibility (EPR), facilitating the sharing of this information with brands.
Crucially, the solution integrates seamlessly and cost-effectively into existing packaging and printing workflows.
Francisco Barrera, Sales & Marketing Director at Saica Flex, explained: "We knew from the start that adoption would depend on keeping things simple. Brands need solutions that fit naturally into their operations and current production environments. This product works across the entire packaging lifecycle, from printing through recycling with minimal disruption. It gives brands meaningful insight, while remaining practical and viable even for high-volume products like milk cartons."
Alice Rackley, CEO of Polytag added: "And because it's built on GS1 global open standards, the UV tag solution is ready to scale across multiple sectors and applications, allowing brands and recyclers to participate fully in building a transparent circular economy."
Rigorous testing for recyclability and safety
The UV inks underwent extensive development and testing to ensure full compatibility with standard waste management processes. The labels can be chipped down or separated through flotation, and any residual ink behaves in line with other approved UV products, ensuring no contamination of recovered materials.
Real-world impact
Francisco Barrera concluded: "Through this collaboration, we're giving brands insight and control over their environmental performance, making recycling measurable, actionable, and scalable. It's a real game-changer for the industry, and we encourage more brands to embrace this solution to make a tangible, positive impact on the circular economy."
Polytag Detection System Deployed at Sherbourne Recycling's state of the art MRF
Polytag together with Sherbourne Recycling announce the successful commissioning of an advanced Polytag detection system at Sherbourne's facility in Coventry.
This installation expands the reach of the Ecotrace Programme, a significant industry-backed effort focused on improving visibility and accountability in packaging recycling. The new system bolsters the network capabilities required for comprehensive, barcode-level monitoring of recycled packaging materials.
The Programme exemplifies effective industry cooperation advancing the circular economy. It benefits from vital investment by major retail brands including Marks and Spencer, Ocado Retail, and Waitrose. Polytag acknowledges the dedication of Sherbourne Recycling's team for their engagement with this initiative.
