Lime desiccant


 
OUKPAK® lime desiccant major component is CaO, which absorbs water via chemical reactions. The amount of water absorbed is not related to the humidity outside and the water absorbed will not return to the dried products because of its evaporation.

Comparing with the physical absorptive silica gel, especially at the state of low humidity, it is a high performance desiccant that has high moisture-absorption rate, excellent long time moisture-absorption property, and with lower cost

Notice for use

①After absorbing moisture, the lime desiccant will expansion, and if your container has no expanding room, it would cause the bag broken. Besides, while using, please avoid bearing, flexing and kneading etc.
②If it is used for the food with high humidity, we suggest you to do the actual packaging test firstly.
③If the content in the desiccant is still effective, don’t let it contact water, because if the lime contacts the water directly it will generate heat immediately.
