Understanding Desiccants in Shipping
When it comes to keeping your shipments safe and dry, knowing about desiccants for container shipping is like having a secret weapon. Let’s dive into what makes desiccants so essential and how to choose the right one for your needs.
Types of Desiccants
Desiccants are hygroscopic materials, which means they love water. They draw in moisture from the air, locking it away to keep your shipments dry and protected. Here’s a look at the most common types you’ll encounter:
-
Silica Gel: This is the stuff you often find in little packets when you buy electronics or shoes. Silica gel is great because it’s non-toxic and can absorb a lot of moisture relative to its size. Plus, it’s got a neat trick – some silica gels change color to show they’re saturated with water.
-
Calcium Chloride: This desiccant is a heavy hitter when it comes to moisture absorption. It’s especially good in situations where there’s a lot of humidity. But, it can turn into a brine (salty water) as it absorbs moisture, so it’s typically used where leakage isn’t a concern.
-
Clay: Yes, the same stuff you might find in your garden. Clay is a natural desiccant that’s effective and affordable. It works best at room temperature, making it a versatile choice for many shipping needs.
-
Container Dri® II: This product is specifically designed for use in shipping containers. It’s powerful at controlling the dew point inside containers, which helps prevent “container rain” – a common problem where condensation forms and drips onto the cargo.
Desiccant Pouches and Bag Sizes
Desiccants come in various sizes, from small pouches that you can toss in with your products, to large bags designed to hang within a container and protect the entire cargo. The size and type of desiccant you need depend on:
- The size of your shipping container
- The nature of the products being shipped
- The length of the journey
- Environmental conditions expected during transit
For example, a standard 40 ft container might need several large bags of Container Dri® II or an equivalent amount of silica gel or clay desiccants. The key is to ensure that you have enough desiccant power to cover the entire journey, keeping moisture levels under control from start to finish.
In Summary
Choosing the right desiccant for container shipping isn’t just about throwing in a couple of packets and hoping for the best. It’s about understanding the conditions your shipment will face and matching the desiccant type and quantity to those needs. Whether it’s silica gel, calcium chloride, clay, or a specialized product like Container Dri® II, the right desiccant can make all the difference in delivering your goods in perfect condition.

Next, we’ll explore how to calculate the precise amount of desiccant you’ll need for different container sizes, ensuring your shipments are protected every step of the way.
How Much Desiccant Do You Need?
When it comes to keeping your shipments dry, the amount of desiccant you need is crucial. Too little, and moisture may sneak in; too much, and you’re spending more than necessary. Let’s break down how to figure out the right quantity of desiccant for container shipping based on container size.
Desiccant for Different Container Sizes
Container Size: The size of your shipping container directly influences the amount of desiccant required. Larger containers hold more air, which potentially means more moisture.
Desiccant Quantity: The rule of thumb is that the larger the container, the more desiccant you will need. However, the specific amount also depends on the type of cargo, the duration of the shipment, and the expected conditions during transit.
Calculation Method: A basic method to calculate the amount of desiccant involves considering the volume of the container, the type of goods being shipped, and the environmental conditions. For sensitive shipments, consulting with desiccant experts or using manufacturer guidelines is wise.
For different container sizes, here’s a brief guide:
-
50 ft Container: Generally, for a container of this size, you might start with a baseline of 32 units of 125-gram desiccant bags, adjusting based on cargo type and journey conditions.
-
100 ft Container: As you double the container size, you don’t necessarily double the desiccant quantity due to volume-to-surface area ratios. Start with about 50-60 units of 125-gram bags and adjust as needed.
-
120 ft Container: For this slightly larger container, consider beginning with 70-80 units of 125-gram bags, with adjustments for specific cargo needs.
-
150 ft Container: This size might require around 100 units of 125-gram desiccant bags. Again, this is a starting point, and specific conditions could alter the need.
Each type of cargo might have its own requirements. For example, electronics need very low humidity, while textiles might be more forgiving. Always refer to the desiccant product’s guidelines for specific recommendations.
In summary, calculating the amount of desiccant for container shipping isn’t just about the container size; it’s about understanding your cargo’s needs, the journey’s duration, and the environmental conditions expected. Starting with the guidelines provided here, and adjusting based on experience and expert advice, will ensure your shipments arrive in top condition, free from moisture damage.
Next, we’ll dive into the best practices for keeping moisture out of your containers, ensuring your goods stay dry and protected from start to finish.
Keeping Moisture Out: Best Practices
When it comes to shipping, moisture is your enemy. It can ruin products, encourage mold growth, and lead to unhappy customers. But don’t worry! With the right strategies, keeping your shipments dry isn’t just possible; it’s pretty straightforward. Let’s explore some effective desiccant solutions and best practices to keep your goods safe and dry:
Improve Ventilation
First up, ventilation. It might sound counterintuitive—open spaces in a container?—but proper air circulation is crucial. It helps to disperse any moisture that does get in, rather than letting it settle on your goods.
Use Insulation
Next, consider insulation. Just like in your home, insulation in a container can help regulate temperature changes. When temperatures inside and outside the container fluctuate, it can lead to condensation. Insulation keeps things steady.
