Montmorillonite Clay 30g — Kraft Paper

Montmorillonite Clay 30g Kraft Paper is the most specialized clay product in CEMACOSG's desiccant range. Montmorillonite (natural smectite clay mineral ≥ 90%) is a premium grade above standard bentonite — its unique silica tetrahedral layered structure provides a surface area of 600–800 m²/g, delivering 10–15% better moisture absorption than bentonite and greater stability at low temperatures (0–10°C). The naturally brown Kraft paper is 100% recyclable and unbleached — meeting the sustainable packaging requirements of EU and North American retailers. Non-GMO, RoHS and DMF-free compliant — satisfying the full green standards set for eco-labeled products.
