Plastic bottle is an important packaging form of pharmaceutical packaging, which is generally composed of a bottle cap and a bottle body. As an important part of packaging, the importance of medicinal bottle caps has become more and more prominent. On the basis of ensuring the integrity and tightness of the packaging, moisture resistance has also become a very important aspect of its basic functions.
The moisture resistance of medicinal bottle caps mainly refers to the packaging of tablets and medicine bottles that need to be stored dry, such as tablets and capsules. These drugs are prone to decomposition, deterioration or adhesion after being damp, which affects the quality of the drugs and even endangers the safety of patients' medication. Therefore, these drugs have relatively high requirements for the moisture-proof performance of the packaging. On the one hand, moisture prevention is to prevent external water vapor from entering the inside of the bottle. On the other hand, the drug or packaging will also contain a small amount of water vapor during the production process. If you do not intervene, it will affect the stability of the drug.
On the one hand, the medicinal bottle cap has an interference fit with the bottle mouth to achieve a good seal and prevent the intrusion of external water vapor. On the other hand, in order to prevent internal moisture from affecting the stability of the drug, a desiccant is also placed inside the package to absorb moisture. Ordinary medicine bottles will put the desiccant inside in a bag. With the continuous development of packaging functionality, some bottles directly put the desiccant on the cap, which not only saves space, but also prevents children from mistakes. Food desiccant, this kind of bottle cap with moisture-proof function is also favored by more and more pharmaceutical companies.
Moisture resistance is only one aspect of the function of pharmaceutical bottle caps. With the continuous improvement of various processing techniques, the functionality of the bottle caps will have more room to play and escort the safety of medicines.
