This provides UK food manufacturers access to a PVC-free closure option intended to cut the risk of unwanted substances passing from the lid into food.
It introduces a sustainability measure that is said to have been independently verified.
Croxsons CEO Tim Croxson said: “We’re delighted that two heritage family businesses, which have more than 250 years of combined packaging expertise between them, and which are completely aligned on sustainability and safety, have come together to bring proven PVC-free technology to the UK market.
“We are very much looking forward to introducing it across our jars as part of our ongoing commitment to quality, performance and packaging safety, while giving our customers the reassurance of enhanced food safety combined with a demonstrable sustainability journey.”
The closures are made using 100% renewable energy, following a 2020 transition from gas-fired thermal drying to induction and UV processes.
The change led to an 81% reduction in CO₂ per closure in 2025 compared with 2011.
PANO has also produced verified product carbon footprint data for individual closures, which customers can include in their own supply chain reporting.
The blue ring, used in Germany as a consumer-facing food safety symbol, was created after major retailers called for PVC-free closures for own-label food products.
PANO produces more than one billion closures each year in 12 sizes.
The products are suitable for cold filling, hot filling and pasteurisation up to 95°C, as well as sterilisation up to 121°C.
PANO Verschluss CEO Thomas Stock said: “At PANO, we believe that true innovation is driven by strong partnerships based on shared values.
“We are very excited to be working with Croxsons, whose commitment to quality, sustainability and innovation makes them the ideal partner to help shape the future of PVC-free closures.
“We look forward to combining our strengths to create sustainable value for both our customers and the industry.”
