sustainable food closures: look for the blue ring

PVC-free food closures, now available through Croxsons across the UK and Ireland

BLUESEAL® is PANO’s range of metal twist closures made without PVC, easily recognised by the distinctive blue sealing ring inside every cap.
 
Through our exclusive partnership with PANO, we are bringing the BLUESEAL® closure technology to food brands, manufacturers and retailers across the UK and Ireland.

Where Green Starts with Blue

Explore the Potential of BLUESEAL® Closures for your Containers

Strong on Sustainability

BLUESEAL® is produced using 100% renewable energy, with gas-fired thermal drying replaced by induction and UV processes in 2020. The result has been an 81% reduction in CO2 per closure (2025 compared to 2011), helping producers lower their overall carbon footprint.

Free from PVC

The BLUESEAL® closure is more than a standard twist-off cap. The seal is made from thermoplastic elastomers (TPE) and is PVC-free, recognisable by the blue colouring.

Free from Plasticisers

For consumers, the blue ring is a sign that the closure contains no plasticisers that could contaminate the contents. BLUESEAL® also has a BPA-NI (Bisphenol A – Not Intentionally Added) inner coating, to avoid the hormone-disrupting risks associated with bisphenol A.

Compliant with EU Requirements

PVC-free and BPA-NI – BLUESEAL® therefore fully fulfils the requirements of the EU, the food industry and retail chains for migration-free packaging.
