Molecular Sieves 3A For Medicine Pill Bottles
0.5-1.0mm molecular sieves 3A desiccant for medicine pill bottle caps
Product introduction:
The application of molecular sieve desiccant in medicine bottle caps is mainly used to keep the bottle dry. It is a synthetic desiccant product with strong adsorption of water molecules, and its pore size can be controlled by different processing techniques. In addition to adsorbing water vapor, molecular sieves can also adsorb other gases. Under high temperatures above 230°C, it can still accommodate water molecules well and absorb a large amount of water vapor in the air under ultra-low humidity conditions. This desiccant is very common in pharmaceutical packaging, especially in medicines such as effervescent tablet tubes, and is used to effectively control the humidity of the internal environment of the effervescent tablet tube.
The use of molecular sieve desiccant in medicine bottle caps is usually to set a small medicine chamber on the top of the bottle cap to store silica gel and molecular sieve. This method can avoid direct contact between the desiccant and the medicine, keep the environment inside the bottle dry, and effectively prevent children from accidentally ingesting the desiccant.
