Activated carbon/charcoal is treated carbon with the function of adsorbing odor. Activated carbon is an excellent odor and gas adsorbent due to its high porosity and large surface area. The activated carbon package can also perform the same task as other desiccants. They are used to control moisture and humidity, and prevent mold, mildew and other damage by virtue of effective moisture absorption. Not only water, they can also be used to remove unstable and odorous particles.

Activated carbon is a kind of carbon processed from coconut shell, which has small and low volume pores and is used to absorb odor. There are two types of desiccant bags:; Roll shape. The cut bag can be put directly into the bottle. If it is rolled, it needs to be installed on the cutting machine, which is directly distributed to the bottle. The adsorption capacity of organic gas is 5 times higher than that of ordinary activated carbon, and the adsorption speed is faster. Cocamite has specific surface area and rich micropore size. The specific surface area can reach 1000-1600m2/g, the micropore volume is about 90%, and the micropore diameter is 10A-40A. It has the advantages of large specific surface area, moderate pore size, uniform distribution, fast adsorption speed and less impurities.
