Cardboard is an important part of the bottle cap. It is attached to the top of the bottle cap and acts as a sealing part of the desiccant compartment to isolate the desiccant from direct contact with the drug. Cardboard is the part that is in direct contact with the effervescent tablet, and its composition, thickness, moisture content, etc. will affect the storage of drugs or the moisture-proof performance of packaging. For example, the function of cardboard is mainly to block and seal. Too much thickness will affect the performance of the desiccant, and too high moisture content will easily make the drug damp, stick, and deteriorate.
