A moisture absorber controls humidity and prevents condensation inside shipping containers.

The Vdry Bags absorb humidity, which reduces the risk of container rain. In some scenarios, container rain can form. Which is when the Vdry Blanket is essential.

At EPG we recommend using a combination of Vdry solutions to interrupt the condensation cycle in the container at various key points and protect cargo against moisture damage.

By marrying high-capacity ingredients with a forensic approach to cargo care, each Vdry product not only ensures optimal protection, but peace of mind, for even the most high-risk shipments.

• Vdry Bags: For high moisture absorption.
• Vdry Blanket: To protect from container rain.
• Vdry Liner: For clean and dry cargo conditions.

Moisture inside shipping containers can lead to condensation, commonly known as “container rain,” which forms when warm air inside the container cools. This condensation can settle on cargo, causing rust, corrosion, mold growth, and mildew. Organic materials like fabrics and food products are prone to spoilage, while metals may corrode or tarnish, compromising the value and usability of goods.

The lifespan of desiccant packs depends on factors like container conditions, humidity levels, and the product’s absorption capacity. On average:

• Vdry cargo moisture bags can last several weeks to months, depending on the journey’s duration and moisture levels.
• Regular inspection and replacement after extended use ensure optimal performance.

As we have already seen there are a variety of unpredictable factors that influence the risk of moisture damage to your cargo. So you should always consider variables such as the voyage length and the nature of your cargo.

Then you need to factor in the absorption capacity of the desiccant bag you are using. Packing your container with 10kg of silica desiccants will give you less protection than 10kg of calcium chloride desiccants.

Conversely, 2kg of calcium chloride desiccants will give you more absorption than 10kg of silica gel desiccants.

Understanding this is not only crucial to protecting your cargo, but also in avoiding overspending on unnecessary desiccant material.

Container desiccants do not absorb all the humidity from the air as soon as they are placed in the container. Instead they gradually absorb a little humidity each day over the course of a voyage. 

This opens up the risk of condensation damage as soon as the temperature starts to fall on the first night after loading. The desiccants have not had the chance to absorb a significant amount of humidity, and condensation will already start to form on the cool container ceiling and walls. 

This cycle will repeat night after night, meaning your cargo will be constantly exposed to container rain.

Goods are also at risk of damage at the end of a voyage when the desiccants have reached capacity.

In these situations that the Vdry Blanket provides constant protection to cargo by

absorbing any condensation that falls from the container ceiling.

The best moisture absorber depends on your cargo type and shipping conditions. Vdry products provide tailored solutions:

• Vdry Bags: Ideal for high-capacity absorption in tight spaces.
• Vdry Blankets: Perfect for combating “container rain” for agricultural and perishable goods.
• Vdry Liners: Best for creating a clean, moisture-free shipping environment for sensitive products.

Each product is engineered for optimal absorption and protection, making Vdry the trusted choice for global shippers.

Neglecting moisture control can result in:

• Spoiled or damaged cargo due to rust, mold, or mildew.
• Financial losses from replacements, customer claims, and shipment delays.
• Damaged business reputation and strained customer relationships.

Investing in reliable moisture absorbers like Vdry products ensures peace of mind and eliminates these risks.
