The vacuum freeze-drying process is usually used for injectable drugs with poor stability to enhance their shelf life by removing moisture from the drugs. In addition to the research and development of freeze-dried formulas and processes, the packaging (containers and sealing parts) of freeze-dried products also plays a crucial role in the quality performance of freeze-dried products. The rubber stopper is one of the important components that cannot be ignored. It can also be said that the rubber stopper is the only seal in contact with the product.

In order to avoid changes in the position of the rubber stopper during transportation and subsequent production processes after filling, freeze-dried rubber stoppers are basically designed with anti-jumping stoppers.
In addition, the freeze-dried rubber plug design also needs to leave a vent. Common designs: single-hole ventilation structure (igloo), double-pronged rubber plug 2-legged, three-pronged rubber plug 3-legged
