受温度、湿度、空气、光、微生物等的影响，药品稳定性会发生变化。

药用玻璃因其长效安全的特点，广泛应用于医药包装领域，

一直被作为水针剂及冻干粉类药物必选的包装材料，有着不可替代的地位。

5.0中硼硅玻璃在耐水性、耐酸耐碱性、抗冷冻性、热稳定性、

灌装速度等方面都远优于7.0低硼硅玻璃，

不易因药品浸泡、侵蚀而产生“脱片”现象，是国际公认的安全药包材。

The stability of the drug is changed by the influence of temperature, humidity,air, light and microorganism.

The borosilicate glass is widely used in thefield of pharmaceutical

packaging as its characteristics of long-term safety,

has been used as a compulsory primary packaging of injection and lyophilizeddrugs with an irreplaceable status.

5.0 Neutralborosilicate glass is superior to 7.0 low borosilicate glass

comparing theaspects of hydrolitic resistance, acid and alkali resistance,

anti-freezing,thermal stability, filling speed and others,

which is not easily to getdelamination due to immersion and erosion of drug itself,

and is worldwiderecognized safe pharmaceutical packaging materials.
