Moisture prevention is a very important function of the effervescent tube, and desiccant is the premise to achieve this function. Desiccant can absorb moisture inside the package and keep the internal environment dry. So, what kinds of desiccants are there in this package?
144mm effervescent tube packaging
Desiccant refers to a substance that can remove moisture from moist substances. Commonly used desiccants include calcium chloride, silica gel, montmorillonite, molecular sieve, etc. Among them, the desiccant used in the effervescent tube is mainly silica gel and molecular sieve, which is also YBB00172004 -The two types of desiccants required in the standard of "Oral Solid Pharmaceutical Low Density Polyethylene Moisture-proof Combination Caps" in 2015.
Molecular sieve desiccant is a synthetic desiccant product with strong adsorption to water molecules. Under ultra-low humidity conditions, it can still absorb a large amount of water vapor in the environment and effectively control the environmental humidity. absorbs a lot of water vapour within a period of time. Silica gel is a highly active adsorption material. The most suitable hygroscopic environment is room temperature (20~32℃) and high temperature (60~90℃). It can reduce the relative humidity of the environment to about 40%, so the application range of desiccant is very widely.
When choosing the desiccant inside the effervescent tube, pharmaceutical companies generally use a mixture of silica gel and molecular sieve in equal proportions, combining the advantages of the two to play a better role in moisture absorption.
