Container Desiccants Against Moisture: Dry Bags as Dehumidifiers for Containers
Sources of moisture in containers are in most cases damp wooden pallets or high humidity. The moisture contained in the stored pallets as well as in the air can condense during a transport of several weeks as so-called "container sweat" and damage the cargo and/or the packaging of the goods. Container desiccants bind the moisture, prevent the formation of sweat and condensation water, and thus avoid damage to pallets and cardboard boxes.
Desiccants are essential to prevent moisture damage during transport. Especially with long transport times in
containers, condensed moisture can lead to significant damage to the loaded goods. Desiccant bags, also known as dry
bags, offer an effective solution to bind moisture and thus protect the quality and integrity of the goods.

Main Applications of Container Desiccants
The use of moisture protection is particularly recommended when transporting metal parts, metal drums, metal canisters, or even high-quality electronics. To avoid corrosion damage, you should create a dry climate inside your container. By creating a dry climate, you can prevent moisture damage in your container. The desiccants therefore serve as dehumidifiers for containers.

Desiccant Packs and Chains for Flexible Applications
Moisture Protection for Sensitive Goods and Packaging
Container Desiccants
In closed containers, your goods are subject to severe climate fluctuations, which can cause moisture damage due to condensation. Sandax Sansorb offers your cargo optimal protection. The Sansorb desiccant chains are simply hung into the container eyes. Due to a diffusion-tight film on the back, all Sansorb variants can, unlike many other products, also be placed directly on top of the goods to be protected if there is no possibility of hanging them up.
Frequently Asked Questions About Desiccants
Below you will find important questions and answers about desiccants, desiccant bags, container desiccants, and moisture protection for export packaging, sea freight, and storage.
What are desiccants?
Desiccants are moisture-absorbing products used to protect goods, packaging, and shipping containers against moisture. They absorb moisture from the surrounding air, helping to reduce the risk of condensation, rust, mould, mildew stains, and damaged packaging.
What are container desiccants used for?
Container desiccants are used to absorb moisture during long journeys. During sea freight, export shipments, and container journeys lasting several weeks, temperature changes and high humidity can cause a phenomenon known as container sweat. Desiccants help absorb this moisture and protect the cargo.
What is container sweat?
Container sweat occurs when moisture from the air or damp pallets and packaging condenses inside a shipping container. Temperature differences can cause water to form on the container walls or ceiling and then drip onto the cargo. This can damage cartons, pallets, machinery, metal components, textiles, and paper products.
What are the advantages of desiccant bags with hooks?
Desiccant bags with hooks can be attached easily to suitable points inside containers, trucks, warehouse shelving, or packaging. This allows them to hang freely, absorb moisture effectively, and save space without being placed directly on the cargo.
What is the difference between a desiccant bag and a desiccant chain?
A desiccant bag is a single unit containing moisture-absorbing material. A desiccant chain consists of several connected units and is particularly suitable for larger containers, long transport routes, or areas where moisture needs to be absorbed across a wider space.
Which goods should be protected with desiccants?
Desiccants are particularly useful for moisture-sensitive goods such as machinery, metal components, electronics, textiles, leather goods, paper products, cartons, wooden packaging, spare parts, tools, and export cargo. Moisture protection is also often advisable for goods transported in sea freight containers or stored for extended periods.
How many desiccant bags are needed per shipping container?
The required quantity depends on container size, transit time, humidity, packaging, pallet material, and climatic conditions. For certain Absorex desiccant bags, Sandax recommends 32 to 36 units for a 20-foot container and 64 to 72 units for a 40-foot container.
What are container desiccants made of?
Many container desiccants contain highly moisture-absorbing substances such as calcium chloride, often combined with carrier materials or starch. This mixture can absorb and retain large amounts of moisture, reducing the risk of condensation and moisture damage.
Where should desiccants be placed inside a shipping container?
Desiccants should be distributed evenly throughout the container and placed where they can function effectively without being damaged. Bags with hooks can be attached to suitable lashing points, container walls, or mounting points. Make sure that potential leakage or abrasion cannot affect sensitive cargo.
Can desiccants also be used in warehouses?
Yes, desiccants can also be used in storage rooms, on shelves, in archives, in temporary storage areas, or inside closed packaging. They help control humidity and protect moisture-sensitive products against damage during storage or interim storage.
Do desiccants replace waterproof packaging?
No, desiccants do not replace waterproof or seaworthy packaging. They provide additional moisture protection and should be combined with suitable packaging, protective film, VCI protection, barrier packaging, or other protective measures for sensitive export goods.
Can I buy desiccants directly from Sandax?
Yes, you can buy desiccant bags, desiccant chains, and container desiccants directly from the Sandax online shop. If you are unsure which quantity or product type is suitable for your shipping container, export packaging, or stored goods, Sandax can provide expert advice.
