New modified glass development packaging applications

By modifying the glass, the application of glass materials in packaging can be more extensive. For example, Asolvex type I glass created by Saint-Gobain is particularly suitable for the packaging of blood products, nutritional products, biological agents and genetic engineering drugs.

The content of Al2O3 in the glass component of Asolvex is reduced by 50% compared to the ordinary type I glass, and the content of silicon is increased accordingly, which makes the precipitation of Al2O3 greatly reduced. In normal non-ionized water, even 75% reduction in sodium gluconate solution. This feature applies to products that are sensitive to trace metals, such as enzymes or products that do not contain preservatives and moderators.

In addition, glass can be coated with any material such as metals, semiconductors, polymers, and the like. Coating a thin coating with a thickness ranging from 1 nm to 1 μm can effectively change its crack resistance and moisture resistance.
