Medicinal glass bottles have a new breakthrough in technology

The widely used glass bottles for pharmaceutical packaging products have achieved new breakthroughs in technology. A new type of glass that can greatly reduce the precipitation of Al2O3 provides pharmaceutical companies with access to new packaging materials.

On May 26th and May 28th, China Pharmaceutical Packaging Association organized the "Seminar on R&D and Selection of Pharmaceutical Glass Materials" in Nanjing and Beijing respectively. The chairman of the French Pharmacopoeia Committee is also the "Packaging" of the European Pharmacopoeia Committee. Professor Daniel Fehel of the Materials Group Expert Group introduced the main characteristics of this glass to the Chinese pharmaceutical industry and its superior performance as a pharmaceutical packaging material.

It is understood that this new type of glass is successfully developed by Saint-Cobain, France. It is a type I borosilicate glass. Its main feature is that the content of Al2O3 in the glass component is reduced by 50% compared with the ordinary type I glass, and the content of silicon is correspondingly Increased, thereby greatly reducing the precipitation of Al2O3. According to figures provided by experts, in the normal non-ionized water case, the glass even reduced Al2O3 in the calcium gluconate solution by 75%. This significant reduction in Al2O3 precipitation makes it possible to obtain new packaging materials because this property is suitable for products that are sensitive to trace elements, such as enzymes or products without preservatives and moderators. Therefore, this kind of glass has great potential in the packaging of blood products, nutritional products, biological agents and genetic engineering drugs.

Domestic pharmaceutical companies have paid great attention to this new glass packaging product. Jing Ling, Nanjing Jinling pharmaceutical preparation professional told reporters that they will learn more about this product, and conduct comparative tests, high-performance packaging materials for the packaging of demanding drugs is very valuable.

Cai Hong, the secretary general of the China Pharmaceutical Packaging Association, also stated that with the improvement of the overall level of the domestic pharmaceutical industry, the issue of how to choose proper packaging forms and packaging materials to ensure quality has gradually attracted the attention of the pharmaceutical industry. Although packaging in the areas of powder injection, infusion, freeze-drying, and biological preparations has made great progress, compared with foreign pharmaceutical industries, the impact of pharmaceutical packaging on the quality of pharmaceuticals in the domestic pharmaceutical industry is still relatively small, and therefore Chinese pharmaceutical packaging The association began to contact with relevant foreign institutions very early and invited experts with the latest technology to visit China and domestic pharmaceutical companies to discuss and discuss new packaging technologies and materials.

However, this new medical glass bottle has a relatively high price, is it acceptable to Chinese pharmaceutical companies? For this, pharmaceutical packaging professional Zhu Bixi believes that the low aluminum formulation, size and strength of this glass can be stable. It is its most competitive advantage, especially in the bottle of blood products has an absolute advantage. "China has had a long history of making glass bottles, but it still lacks technical advantages." Zhu Bixi is very optimistic about this new product, and believes that it has unique features in formulating, smelting technology, bottle making and testing. Looking back at domestic products, "the price is unreasonably low, so how can we have the money to develop technology?"
