Pharmaceutical glass bottles are mainly used for the packaging of injections and other products. Their chemical stability directly affects the quality of drugs. Pharmaceutical glass bottles have obvious advantages compared with the glass materials commonly used in domestic injection enterprises at present: small linear expansion coefficient, strong resistance to extreme cold and extreme heat, more suitable for freeze-dried products: not easy to crack in processing, high mechanical strength, strong impact resistance: good chemical stability, high acid, alkali and water resistance, can guarantee drugs. The validity period, especially the water injection preparation, reduces and avoids the occurrence of white spots, flakes and visible foreign bodies.
The raw materials of high borosilicate glass bottles contain silicon and boron. The expansion rate of high borosilicate glass bottles is low and the chemical properties are stable. Most medicines contain acid and alkaline substances. Some special medicines also contain corrosiveness. Choosing high borosilicate glass bottles with stable chemical properties will avoid reacting with filled medicines. The high borosilicate glass bottle has strong mechanical strength and will not break under external force during transportation. The high borosilicate glass bottle has high transparency and intuitive filling medicine. No matter what color the lid is, it will appear high-grade. It can improve the grade of filling medicine and marketing means. The most important point is that high borosilicate glass is recognized as safety glass in the world. It does not contain any toxic substances. That is to say, high borosilicate glass bottles are the safest to fill medicines. In our life, we have been very concerned about the safety of medicines. If the container is unsafe, it will affect the filled medicines. With high borosilicate glass bottles, we can safely fill medicines.
