Plastic bottle is an important packaging form of medical packaging, which is generally composed of bottle cap and bottle body. As an important part of packaging, the importance of medical bottle caps has become increasingly prominent. On the basis of ensuring the integrity and sealing of packaging, moisture-proof has become a very important aspect of its basic functions.
Moisture-proof cover
The moistureproof property of medical bottle caps mainly refers to the packaging of tablets, capsules and other tablets that need to be dried and preserved. These drugs are easy to decompose, deteriorate or adhere after being affected with moisture, which affects the quality of drugs and even endangers the safety of patients. Therefore, these drugs have high requirements on the moisture-proof performance of packaging. On the one hand, moisture-proof is to prevent external water vapor from entering the inner part of the bottle; on the other hand, drugs or packaging will also carry a small amount of water vapor during the production process, which will affect the stability of drugs if not intervened.

Universal screw cap
On the one hand, medical bottle caps can achieve good sealing performance and prevent external water vapor intrusion through interference fit with the bottle mouth. On the other hand, in order to prevent the internal moisture from affecting the drug stability, desiccants will also be placed inside the package to absorb moisture. Ordinary medicine bottles put desiccant in bags. With the continuous development of packaging functionality, some bottles directly put desiccant on the bottle cap, which not only saves space, but also prevents children from eating desiccant by mistake. This kind of cap with moisture-proof function is also favored by more and more pharmaceutical enterprises.

The moisture-proof function is only one aspect of the functions of medical bottle caps. With the continuous improvement of various processing technologies, the functionality of bottle caps will have more room to play and escort drug safety.
