Built for Reliable Long-Haul Moisture Protection
Selected Raw Materials
Carefully selected calcium chloride, silica gel and mineral absorbents from qualified long-term suppliers. Incoming materials are inspected to maintain consistent absorption performance from batch to batch.
Quality & Compliance Support
Manufactured under an ISO 9001 quality management system, with export documentation including RoHS, REACH, DMF Free, MSDS/SDS and COA for international shipments.
Reinforced Leak-Resistant Packaging
Available with DuPont™ Tyvek®, non-woven fabric, Aihua paper and fiber paper. Heat-sealed or ultrasonic-sealed seams help resist tearing and leakage during loading and long-distance transport.
Long-Lasting Moisture Control
High-capacity calcium chloride can absorb up to approximately 300% of its own weight. Moisture is gradually captured and locked into gel, helping maintain reliable protection throughout long-haul ocean transportation.
Responsible Packaging Options
Packaging structures can be optimized to reduce unnecessary material while maintaining strength for export transportation, with support for RoHS, REACH and applicable PPWR requirements.
Fast & Easy Installation
Open the outer package and hang the desiccant directly on the container side wall or upper fixing point. No tools or complicated installation steps are required, saving loading time and simplifying operation.

FAQ
Frequently Asked Questions About Container Desiccant Bags
Answers to common questions about our factory, desiccant materials, container dosage, samples and custom orders.
1. Are you a manufacturer or a trading company?
We are a direct desiccant manufacturer with 19 years of manufacturing experience. AbsorbKing operates two modern production bases in Jiangmen, Guangdong and Huai'an, Jiangsu.
Our headquarters is located in Shenzhen, and we also have a regional company in Indonesia to support overseas customers.
Our factories support bulk production, standard desiccant supply, OEM/ODM customization, packaging printing and export order fulfillment.
2. How should I choose between silica gel, calcium chloride and montmorillonite?
The best material depends on humidity, transport time, packaging type and the level of moisture protection required.
- Calcium Chloride: up to about 300% moisture absorption. It is suitable for high-humidity environments, ocean freight and long-distance container transport.
- Silica Gel: approximately 30% moisture absorption. It provides stable dry adsorption and is suitable for packaged goods, crates and general storage.
- Montmorillonite: approximately 8% moisture absorption. It is a mineral-based option suitable for applications where stable adsorption and no free liquid are preferred.
We can also develop blended desiccant formulas according to your required performance and cost target.
For example, an initial blended formulation may use approximately 60% montmorillonite, 30% calcium chloride and 10% starch/binder. The final ratio should be adjusted according to humidity, packaging structure, transit duration and actual absorption testing.
3. How many 1kg desiccant strips should I use for a 20ft or 40ft container?
Taking a 1kg calcium chloride container desiccant strip as an example:
- 20ft container: approximately 6–8 strips
- 40ft container: approximately 10–12 strips
- 40ft high-cube container: approximately 12–14 strips
The final quantity can vary depending on cargo type, shipping route, transport duration, humidity, container condition and packaging method. Send us your application details and we can recommend a more suitable moisture-control solution.
4. Can I get free samples and what is the minimum order quantity?
Yes. We can provide free samples and sample-making support for product evaluation before a bulk order.
- Standard products: MOQ is usually around 10,000 bags.
- Customized products: MOQ is usually around 100,000 bags.
We can customize packaging material, desiccant raw material, fill weight, printing, language and other specifications. Actual MOQ and specifications can be adjusted according to your project requirements. Please contact our sales team for confirmation.
