Ecosecur - Type II glass

Stoelzle’s Type 2 glass represents the next generation of pharmaceutical packaging, combining enhanced product protection with process efficiency and sustainability. Developed through an innovative inner-surface treatment, this solution ensures consistent hydrolytic resistance and reliable performance across all container sizes. Ideal for acidic and neutral aqueous formulations, Type 2 glass provides a high level of chemical durability while maintaining the flexibility of Type 3 glass manufacturing. This allows for efficient production without compromising on quality or compliance with international pharmacopoeia standards. The controlled surface treatment not only improves product stability but also supports precise and reproducible dosing—an essential factor for pharmaceutical applications. Beyond performance, sustainability is at the core of this innovation. The optimized process reduces the use of chemicals and resources, contributing to a lower environmental footprint while maintaining the highest quality standards.
