Molecular sieve

Molecular sieve is a synthetic desiccant with strong adsorption to water molecules. In addition to adsorbing water vapor, it can also adsorb other gases. In the case of high temperature above 230 ℃, it can still hold water molecules well. This kind of desiccant is also used in medical packaging.

Molecular sieve desiccant is made of alkali (sodium oxide, potassium oxide, calcium oxide, etc.), aluminum sulfate (or gibbsite, aluminum trichloride, etc.), silicon oxide (or silicon chloride, silicic acid, etc.) and water as raw materials , A crystal with a skeleton structure synthesized through the process of compounding, gel forming, heating, crystallization, ion exchange, molding, activation, etc., and then after dehydration treatment, it exhibits extremely strong adsorption performance. Under ultra-low humidity conditions, it can still absorb a large amount of water vapor in the environment and effectively control the environmental humidity; the moisture absorption rate is extremely fast, and it can absorb a large amount of water vapor in a very short time.

effervescent tablet packaging

desiccant bottle

Effervescent tablet packaging is mainly used to contain VC effervescent tablets. This type of tablet requires relatively high moisture-proof performance of the packaging. It is used to store desiccants such as molecular sieves in the small drug warehouse of the bottle cap to absorb the moisture inside the package to ensure The medicine has a stable storage environment.

The desiccant in pharmaceutical packaging is not only a molecular sieve, but also silica gel or a mixture of the two in equal proportions. They play an important role in protecting the stability of the drug and avoiding moisture deterioration.
