Stoelzle upgrades EcoSecur pharma glass coating process
Stoelzle Glass Group has refined the manufacturing process behind its EcoSecur Type 2 pharmaceutical glass, switching to an enhanced liquid-injection inner-surface treatment at its Koflach, Austria site. The company says the change improves coating consistency and hydrolytic resistance for injectable and infusion products, and will present it at CPhI Worldwide 2026 in Milan from 6 to 8 October.
Why this mattersTighter process control on Type 2 glass coatings could support pharma packaging quality claims as customers scrutinise hydrolytic resistance for injectables.
- EcoSecur has been commercially available since 2021.
- Production uses a liquid-injection process at Stoelzle's Koflach, Austria pharmaceutical glass site.
- EcoSecur is made from Type 3 soda-lime glass treated to give Type II performance, in flint and amber, 7ml to 500ml.
- Stoelzle will showcase the enhanced process at CPhI Worldwide 2026, Milan, 6-8 October, booth 11C74.
