Activated Clay

Activated clay, also known as bentonite clay, is a natural mineral desiccant that absorbs moisture effectively, up to 25% of its weight. The moisture absorber is safe, odourless, non-corrosive, and non-toxic.

Effective Humidity Control

Ideal for moisture-sensitive products like electronics, pharmaceuticals, and food, montmorillonite clay desiccants find application in packaging. The natural clay moisture absorber is available in desiccant packets for packaging or shipping containers, shielding contents from moisture during storage and transportation.

Processed through heating and chemical treatment, it develops a porous structure with ample surface area and small pores. This structure enables the porous clay desiccant to adsorb moisture from the air, controlling humidity and eliminating problems such as corrosion, mould growth, and product deterioration.

When exposed to temperatures above 50°C, the bentonite clay desiccant releases the absorbed moisture into the environment, allowing for reusability. They can ensure the integrity and quality of sensitive products like electronics, pharmaceuticals, and food items.

Natural Moisture Absorption

We offer a range of customisation options in terms of size and specifications for tailored packaging solutions. Maintaining high standards, our in-house QA laboratory conducts daily quality checks conforming to ISO 9001 and 14000 standards. This ensures that the clay desiccant consistently meets expectations, providing optimal moisture protection.
