When goods are transported over long distances by sea, they’re exposed to constant changes in temperature and humidity. These fluctuations create the perfect conditions for moisture build-up inside shipping containers, leading to problems like condensation (also known as container rain) which is a major cause of cargo damage worldwide.


As an official UK supplier, our SeaDry container desiccants provide a highly effective solution to this challenge, helping logistics professionals protect cargo and save money.

Why Moisture Is a Problem During Shipping

Shipping containers are often sealed and packed tightly to maximise space. However, these conditions make them especially vulnerable to condensation. As vessels pass through different climates, air pressure and humidity levels shift rapidly, causing moisture to form on container walls and ceilings.

This moisture can drip onto products such as:
• Food items (which can spoil or grow mould)
• Metal parts (which may rust)
• Packaging materials (which can become soggy and collapse)

This damage not only results in lost inventory but can also harm customer relationships, increase return rates, and severely disrupt supply chains.

How SeaDry Container Desiccants Work

Our SeaDry desiccants are engineered to absorb up to 200% of their own weight in moisture, making them some of the most effective desiccants on the market. They actively extract moisture from the air inside the container, reducing relative humidity and helping to prevent condensation from forming.

Superior Absorption for Long-Distance Journeys

Because SeaDry desiccants continue working for an extended period, they are ideal for transatlantic or intercontinental shipments. They outperform traditional alternatives by maintaining absorption over long durations, reducing the risk of damage from re-evaporated water and recurring condensation cycles.

Leak-Proof Design: A Key Advantage

One common issue with standard desiccants is that they can leak once saturated, especially on longer shipping routes. SeaDry eliminates this problem. When moisture is absorbed, the contents harden and lock water in, preventing any liquid from escaping.

Fewer Units Required = Less Waste & Lower Costs

Thanks to their exceptional absorption capacity, SeaDry desiccants require fewer units per container, meaning:
• Lower total shipping costs
• Less packaging waste
• Reduced disposal effort at the destination
• More efficient and sustainable logistics

This also makes them a cost-effective solution compared to alternatives that require higher quantities for the same level of protection.

Versatility for a Wide Range of Applications

SeaDry desiccants can be used in virtually any scenario involving moisture-sensitive products. Their flexible design allows them to be used in:
• Sea containers
• Medium to long-term storage units
• Caravans and boats
• Warehouses and confined spaces

Easy to Install

Our product range includes:
• SeaDry hanging strips – attach easily to container walls using lashing lugs.
• Sachets and loose packs – place directly next to goods or between layers of cargo.
