Pharmaceutical moisture-proof bottle caps are generally made of low-density polyethylene (LDPE) as the main raw material. The bottle caps contain silica gel desiccant (silica gel: large molecular sieve 3:1) in the small medicine bin, which is cut off by cardboard. Most of the pharmaceutical companies according to their own product ingredients, the requirement to be based on fine silica gel.
The appearance of fine silica gel desiccant is white and translucent. Mainly used for drying, moisture proof, can be used as catalyst carrier and dehydration of organic compounds refining. Due to its high packing density and low humidity under the hygroscopic effect of obvious characteristics. It can be used as air purifier to control air humidity by removing moisture from the air. It is also widely used in Marine applications and can be used as a dehumidifier between two parallel sealed glass panels to maintain the transparency of the glass.
