Montmorillonite desiccant is a natural mineral that has been dried to produce an adsorbent material. Montmorillonite desiccant is easily placed inside the containers or cartons by attaching directly to cargo, which is a good choice to protect goods from deterioration, rust, corrosion, mold, mildew, and other damage caused by moisture or high humidity. In general, it offered high performance at a low cost in comparison to other chemically produced desiccants.
Bentonite Desiccant also called montmorillonite clay desiccant pack, it is one kind of desiccant made of natural ores using such techniques as high temperature heating, organic carbonization, Montmorillonite swelling, streaming treatment, drying, activation, crushing, and screening concentration.

Montmorillonite bentonite desiccant, mainly composed of Montmorillonite, can be used as feed supplement filter, aid detergent, cosmetics, additive in toothpaste and caking agent in pharmacy. As a medicine book named BenCaoShiYi records, Montmorillonite is able to eliminate toxins. And Dioctahedral Smectite, a stomach medicine from France, is also mainly composed of Montmorillonite.

Notice:
The product should be placed in the suitable part of container to ensure the moisture effect in complete room airproofed. Add the desiccant amount to prevent loss caused by water coagulation when protecting valuable material.
Reuse Method:
To improve the activity and reuse the bentonite desiccant after using for a certain period time, drying it in the constant temperature of 140 °C in oven to 1% moisture content.
