Magnesium Chloride Desiccant
Magnesium chloride desiccant is a powerful moisture absorber made from anhydrous magnesium chloride and starch-based polymer. It quickly absorbs moisture from the environment and turns into a solid block for safe, leak-free performance.
The packaging uses durable Tyvek Paper / Dulai Paper materials that are dust-proof, wear-resistant and corrosion-resistant, helping prevent dust leakage while improving moisture protection.
Available in multiple formats including sachets and hanging strips.
Products can be tested and documented for global export standards, including REACH, RoHS, SGS test reports and MSDS chemical composition reports.
Magnesium Chloride Desiccant Dehumidifier Bag
- Main Ingredients: MgCl2 Powder + starch-based polymer
- Appearance: Powder when dry, solid block after wetting
- Absorption Capacity: Up to 300% at 50 C and 90% RH
- Working Temperature: -20 C to 90 C
- Humidity: 10% to 100% RH
- Packaging Safety: Leak-proof, dust-free and moisture-locking
- Environmental Safety: Non-toxic, odorless, eco-safe, DMF-free
Magnesium chloride desiccant bags are engineered for moisture control in packaged goods, storage environments and transit protection. Each sachet contains a blend of anhydrous magnesium chloride and starch-based polymer that absorbs humidity and locks it into a stable gel-like block.
Features
- Exceptional absorption up to 300% of its weight at 50 C and RH 90%.
- Leak-free solidification turns absorbed water into a stable mass with no dripping.
- Reinforced breathable HDPE fabric and Tyvek-style composite packaging resist dust, tearing and chemical wear.
- DMF-free material system with RoHS, REACH and international safety documentation support.
- Custom sizes available from 2 g, 5 g, 10 g, 25 g, 50 g, 100 g and buyer-specified formats.
How Does It Work?
When exposed to moisture in the air, anhydrous magnesium chloride absorbs water molecules and transforms the dry powder into a solid mass.
This process prevents reverse diffusion, so the moisture is trapped inside the packet. The gel remains stable and sealed, with no leakage and no mess.
