Product Description
What is Container Desiccant Strip?
Container desiccant strip is a high-absorption calcium chloride desiccant designed specifically for large enclosed spaces like shipping containers. During long ocean voyages, temperature fluctuations inside a container can cause "container rain" — condensation that forms on the ceiling and walls and drips onto cargo, causing serious moisture damage. Container desiccant strips absorb this excess moisture, helping keep humidity levels low throughout the journey. As the calcium chloride absorbs moisture, it gradually forms a stable gel, helping to lock the absorbed moisture in place and reduce the risk of leakage. Our Calcium Chloride Desiccant Packets product uses the same high-absorption calcium chloride formula in a smaller, retail-friendly format.
Benefits
- High-absorption formula — absorbs over 300% of its own weight in moisture, making it well suited to long-duration, high-humidity shipping environments
- Wide temperature tolerance — performs reliably from -35°C to 95°C, covering the range of conditions containers may experience during transit
- Flexible configurations — available in single, double, or triple-layer formats to match different container sizes and moisture loads
- Leak-resistant design — forms a stable gel after saturation, helping contain absorbed moisture
- Multiple packaging options — choose from PP non-woven fabric, carton board shell, laminated fabric, transparent film, or Tyvek to match your logistics needs
Applications
Container desiccant strips are widely used to protect cargo during shipping and storage:
- In shipping containers, they prevent "container rain" from dripping onto cargo during ocean freight.
- In long-distance export shipping, they provide extended moisture protection across multi-week voyages.
- In warehouse and bulk storage, they help maintain low humidity for goods held over extended periods.
- In industrial equipment, textiles, and electronics shipments, they protect sensitive cargo from moisture-related damage during transit.

FAQ
Q1: How many container desiccant strips do I need for a shipping container? The right quantity depends on your container size, cargo type, and shipping duration. Contact our team with your container specifications for a tailored recommendation.
Q2: Is container desiccant strip reusable? No, calcium chloride is a single-use desiccant. As it absorbs moisture, it gradually forms a gel and cannot be dried out and reused.
Q3: What sizes are available? Container desiccant strips are available in 1kg and 2kg sizes, in single, double, or triple-layer configurations.
Q4: What is the minimum order quantity? MOQ is based on your specific quantity and configuration needs. Please contact our team for a tailored quote.
