Reliable High-Humidity Moisture Protection for Industrial Packaging, Storage, and Shipping
SORBSTAR® delivers high-performance industrial desiccant solutions designed for demanding logistics, export, and storage environments worldwide.
Magnesium chloride desiccant is a high-performance moisture absorber widely used in industrial packaging, transportation, and storage applications where humidity control is critical. Due to its strong hygroscopic and deliquescent properties, magnesium chloride rapidly absorbs moisture from the air and converts it into a stable solid block, making it especially effective in high-humidity and long-duration exposure environments.
Compared with traditional desiccants such as silica gel or clay, magnesium chloride desiccant offers significantly higher moisture absorption capacity, allowing industrial users to achieve reliable protection with fewer units and lower overall cost. It is commonly selected for export packaging, container shipping, warehouse storage, and industrial equipment protection.
Technical Highlights:
Up to 300% moisture absorption capacity (weight at 50°C, 90% RH, SGS tested)
Turns absorbed moisture into a solid block with no leakage, ensuring safe and mess-free use in enclosed spaces.
Complies with REACH, RoHS, SGS, and MSDS certifications for export and industrial use.
Constructed with durable Tyvek® Paper / Dulai Paper packaging to prevent dust and enhance moisture protection.
SORBSTAR® magnesium chloride desiccant is formulated with anhydrous MgCl₂ plus starch-based polymer. When exposed to ambient moisture:
The MgCl₂ triggers a chemical hygroscopic reaction that absorbs water vapor from air.
Moisture is permanently locked into a solid mass, eliminating risk of liquid drip or reverse diffusion.
This makes it highly effective in environments with wide humidity ranges (10%–100% RH, -20°C to 90°C)—ideal for protective packaging, storage, and extended transit conditions.

SORBSTAR® magnesium chloride desiccant is widely used inside industrial and export packaging to protect moisture-sensitive products.
Typical Applications:
Electronics and electrical components
Auto parts and precision metal components
Hardware, tools, and mechanical assemblies
Moisture Risks Addressed:
Corrosion and oxidation
Mold and mildew formation
Degradation of sensitive materials
Desiccant units are placed directly inside cartons, sealed packaging, or export crates to ensure consistent humidity control throughout the supply chain.
During long-distance shipping, especially sea freight, cargo is exposed to extreme temperature changes and high humidity. Magnesium chloride desiccant is commonly used to protect goods from moisture damage caused by container rain and condensation.
Common Use Scenarios:
Sea freight containers
Long overland transport
High-humidity regional transit
SORBSTAR® strips and sachets help prevent container rain, condensation, and corrosion, making them ideal for marine and intermodal logistics.
Uncontrolled humidity in warehouses can cause long-term damage to stored goods. SORBSTAR® magnesium chloride desiccant helps create a stable, dry micro-environment in enclosed spaces.
SORBSTAR® desiccants help maintain dry environments for:
Spare parts inventory
Finished goods storage
Sensitive industrial equipment
By reducing excess moisture, magnesium chloride desiccant extends product shelf life and reduces maintenance and replacement costs.
Placing desiccants in SORBSTAR® magnesium chloride desiccants are widely used to protect sensitive industrial equipment from internal condensation.
Typical Equipment
Electrical control cabinets
Switchgear and power distribution boxes
CNC machines and industrial systems
Effective moisture control improves operational reliability and reduces downtime.
Recommended Products:
SORBSTAR® magnesium chloride desiccant is available in multiple industrial formats:
Desiccant bags for cartons and packaging
Hanging desiccant strips for containers and large enclosures
Bulk absorbent packs for warehouse and storage applications
Selection is based on enclosure volume, humidity level, transit duration, and protection requirements.
Compared with silica gel and clay desiccants, SORBSTAR® magnesium chloride desiccants provide:
High-humidity performance: Up to 300% absorption (MgCl₂ based) vs lower rates of silica gel.
Leak prevention: Solid block formation provides safer use than gel – leakage prone types.
Wide temperature range: Performs in -20°C to 90°C environments.
Greater efficiency for long-term shipping and storage
These characteristics make SORBSTAR® magnesium chloride desiccant especially suitable for industrial packaging, container shipping, and high-humidity applications, where moisture damage leads to significant quality issues or loss.
To select the optimal SORBSTAR® magnesium chloride desiccant, consider:
Size and volume of the enclosed space
Expected humidity level and exposure duration
Transportation conditions and route
Required absorption capacity and packaging format
Professional selection ensures optimal moisture protection and cost efficiency.
