Stoelzle has developed EcoSecur, a groundbreaking process for the inner-surface treatment of type 2 pharma glass. This technique utilises a liquid treatment process that enables precise dosing customised to the size of each bottle.

Type 2 glass, also know as treated soda-lime glass, is specifically used for containers with liquid products that are characteristically acidic or alkali-neutral. Stoelzle's EcoSecur type 2 glass product line includes a wide range of sizes, from 6ml to 500ml, available in both flint and amber glass options. They are fully compliant with EU and US pharmacopeia and ensure the highest safety for patients. By utilising a liquid treatment agent and an innovative process, the company has achieved reliable and precise dosing tailored to the glass size. This liquid-based approach also reduces the need for chemical materials, making the process safer.

The EcoSecur process reduced the use of chemical components by up to 50% while decreasing CO2 emissions by up to 80%. This significant reduction translates into a minimised environmental footprint. Furthermore, by using liquid ammonium sulphate, Stoelzle have addressed concerns associated with chemical usage. Introducing process automation and automated control during the industrialisation phase guarantees compliance with predetermined conditions at each stage of the process. Automatic adjustments and controls ensure accurate treatment for every bottle. This comprehensive automation creates a controlled manufacturing environment with 100% oversight, utilising state-of-the-art inspection machines equipped with fibre optic and chamber inspection systems.
