Two desiccant forms of tablet bottle

Desiccant is a necessary moisture-proof and dehumidifying product in pharmaceutical packaging. Its function is mainly to absorb the moisture inside the pharmaceutical packaging, so as to achieve the effect of moisture-proof, mildew-proof and extend the shelf life of the medicine. The tablet medicine bottle is a commonly used packaging for tablet solid medicines, and its desiccant is mainly delivered in two forms: bagged and built-in bottle cap.

Bag desiccant: This delivery method is to seal the desiccant into non-woven fabric or polyethylene composite paper and place it directly inside the package. It is also a commonly used desiccant placement method for solid drugs. However, this method can easily cause children to eat desiccant by mistake and endanger their health.

Built-in desiccant cap: This method uses the space on the top of the tablet medicine bottle cap to seal the desiccant inside the cap to achieve the purpose of moisture prevention. Compared with the bagged desiccant, this method saves internal space, reduces the direct contact between the medicine and the desiccant, and to a certain extent can also prevent patients or children from ingesting the desiccant by mistake.

At present, the method of built-in desiccant in the bottle cap is an important innovation in the packaging of medicine packaging materials. It has been applied to a variety of solid medicines such as effervescent tablets, and has gradually become the mainstream direction of moisture-proof tablet medicine bottles. In addition, when choosing medicinal desiccants, it is required to ensure safety and environmental protection, non-toxic and harmless, and super hygroscopic properties. Generally, silica gel or molecular sieve desiccants are mainly used.
