How to Improve Moisture Protection in Packaging with Desiccants
Moisture is one of the leading causes of product damage during storage and transportation. Whether you’re shipping electronics, pharmaceuticals, textiles, or food items, inadequate moisture protection can result in mold, corrosion, degradation, and reduced shelf life.
One of the most effective ways to solve poor moisture protection in packaging is by using desiccants—specialized materials that absorb and control humidity inside sealed packages.
What Are Desiccants?
Desiccants are moisture-absorbing substances commonly used in packaging to maintain dryness and prevent humidity-related damage. The most widely used types include:
Silica gel desiccants – Ideal for electronics, food, and pharmaceuticals
Clay desiccants – Economical and suitable for general packaging
Molecular sieve desiccants – High-performance for extreme humidity control
Calcium chloride desiccants – Excellent for heavy-duty industrial applications
Why Moisture Protection Fails in Packaging
Lack of airtight sealing
No moisture barrier materials
Failure to use appropriate desiccant unit quantity
Absence of visual humidity indicators
If your packaging lacks proper moisture protection, products can be damaged long before they reach the customer.
How Desiccants Solve the Problem
Incorporating desiccants into your packaging offers a simple, low-cost solution:
✅ Prevents mold and mildew in textiles, leather, and shoes
✅ Stops corrosion in metal parts, machinery, and electronics
✅ Preserves freshness of food and supplements
✅ Extends shelf life of pharmaceuticals and medical devices
✅ Protects valuable goods during long-term storage or shipping
Desiccants maintain low relative humidity inside the package, especially when used in vacuum-sealed, aluminum foil, or plastic barrier packaging.
Best Practices for Using Desiccants
Choose the right desiccant type for your product and environment
Calculate the proper desiccant unit quantity based on container volume
Use indicating silica gel for real-time moisture detection
Pair with moisture barrier films or vacuum pouches
Store unused desiccants in airtight containers to maintain effectiveness
