ARMOR SHIELD 16 oz clay desiccant packets in sewn cloth construction are designed to absorb and hold moisture in large enclosed spaces including export shipping crates, palletized freight, long-term storage enclosures, and warehouse transit packaging. The clay adsorbent holds absorbed moisture without changing size or shape, eliminating the risk of pooled liquid damage inside sealed enclosures. Packed 150 units per drum for high-volume industrial and export packaging operations.
Specs: 16 oz unit weight | Clay adsorbent | Sewn cloth construction | FDA, USDA, and Military compliant | 150 units/drum
Applications
- Export crate and sea container moisture control for international machinery and industrial goods shipments

Material Notes
Clay desiccants use montmorillonite clay as the adsorbent medium. Unlike silica gel, clay desiccants are most effective at moderate relative humidity levels (20–80% RH) and at ambient temperatures up to approximately 120°F (49°C). Above this threshold, clay desiccants may begin to release absorbed moisture rather than continue adsorbing. For high-temperature or very low humidity applications, silica gel may provide better performance. The sewn cloth outer construction is more durable than glued or heat-bonded alternatives under vibration and rough handling during freight transit.
Use Case Notes
A 16 oz clay packet is sized for large enclosures. For standard 20-ft. ISO shipping containers, multiple packets are typically required depending on cargo hygroscopicity and transit lane humidity profiles. Placement near ventilation points and along container floor edges maximizes adsorption effectiveness. For crated machinery, position packets adjacent to machined surfaces and enclosed cavities most susceptible to condensation during temperature cycling.
Common Questions
Q: What is the difference between clay and silica gel desiccants?
A: Clay desiccants are more economical and perform well at standard ambient humidity and temperatures. Silica gel provides higher adsorption capacity and better performance in very low humidity or high-temperature environments. For most general export and storage applications, clay is the preferred, cost-effective choice.
Q: Are these safe to use with food shipments?
A: Yes. These desiccants are FDA and USDA compliant for use in food packaging and storage environments.
Q: How many units are in a drum?
A: 150 units per drum.
Q: Can the packets be reused after saturation?
A: Clay desiccants can be regenerated (dried out) by heating to 250–300°F (121–149°C) in an oven. For single-use industrial applications, replacement with fresh packets is standard practice.
Why Buy
Large-unit clay desiccants are a commodity procurement item in export packaging, where unit cost, reliable compliance documentation, and consistent adsorption performance determine total supply chain value. ARMOR SHIELD packets carry FDA, USDA, and Military compliance documentation, providing traceability for regulated shipments and reducing qualification burden for defense and food-adjacent export operations.
