Firstly, Container desiccants play a crucial role in reducing humidity levels inside shipping containers, thereby minimizing the need for additional in-box protection. Imagine fixing a leaking roof instead of using buckets to collect dripping water – that’s the essence of using container desiccants. In this article, we will explore the various types of desiccants available, their installation methods, and the benefits they offer to ensure the safe transportation of goods. shipping container desiccant

Understanding Container Desiccants

Secondly, Container desiccants are designed to absorb moisture and reduce humidity levels within shipping containers. By doing so, they prevent the formation of mold, mildew, and corrosion, which can damage the goods being transported. There are two main types of desiccants commonly used: horizontal and vertical.

Horizontal Desiccants

Horizontal desiccants are placed on top of the cargo, usually on a pallet or other similar platforms. These desiccants offer several advantages over their vertical counterparts. Firstly, they provide higher absorption per kilogram of desiccant installed, ensuring better moisture control. Additionally, horizontal desiccants minimize the carbon footprint as no additional accessories are required for installation.

Vertical Desiccants

Vertical desiccants, on the other hand, are installed in container lashing rings and occupy minimal space in the container. They can either fit into the container walls or be placed close to the container ceiling. While vertical desiccants are effective in reducing humidity levels, they may not offer the same level of absorption as horizontal desiccants.

Types of Container Desiccants

Container desiccants are available in different forms, including gel and liquid desiccants. Let’s explore each type in detail:

Gel Desiccants

Gel desiccants absorb moisture and bind it into a gel-like substance, preventing any leakage. This feature makes them suitable for horizontal installation, as the absorbed moisture remains contained within the desiccant. Gel desiccants are commonly used in various industries, including agriculture, furniture, automotive, and food transportation.

Liquid Desiccants

Liquid desiccants, also known as collector desiccants, capture the absorbed moisture in a collector. These desiccants are versatile and can be used in both horizontal and vertical installations. Liquid desiccants are particularly effective in preventing container rain or cargo sweat during long-distance shipments, ensuring the goods remain dry and undamaged.

Choosing the Right Desiccant

When selecting a container desiccant, it’s essential to consider factors such as the type of cargo, shipping conditions, and container size. Different desiccants have varying absorption capacities and installation requirements. Consulting with a desiccant expert or supplier can help you determine the most suitable desiccant for your specific needs.

Installation Methods

Proper installation of container desiccants is crucial to ensuring their effectiveness. Here are two common installation methods:

Adhesive-Backed Bags

Adhesive-backed desiccant bags, such as the Continu-Strip, can be easily applied to container walls. These bags come in strips, with six bags per strip. The adhesive backing allows for secure attachment and ensures that the desiccant remains in place throughout the shipment.

Hanging Desiccant Bags

Hanging desiccant bags, like the EZ Hang Pole, are designed with a wooden spine and a hook for easy hanging inside containers. These bags are particularly useful when reaching high areas of the container without the need for stools or step ladders. They provide efficient moisture absorption while maximizing space utilization within the container.

Benefits of Container Desiccants

Container desiccants offer several benefits that contribute to the safe transportation of goods. Let’s explore some of these advantages:

Moisture Control

The primary function of container desiccants is to control humidity levels and prevent moisture-related damage. By absorbing excess moisture, desiccants inhibit the formation of mold, mildew, and corrosion, preserving the quality and integrity of the cargo.

Environmental Safety

Container desiccants, when chosen from reputable suppliers, are environmentally safe and compliant with food and drug applications. This ensures that the desiccants themselves do not pose any harm to the cargo or the environment.


Container desiccants can be used in various shipping scenarios, including rail, ocean, and air shipments. They are suitable for transporting a wide range of goods, such as agricultural products, furniture, auto parts, pet food, textiles, and more. Additionally, desiccants can be used in marine vessels and recreational vehicles to protect food and belongings from weather-related damage.


By reducing the need for additional in-box protection, container desiccants can help lower shipping costs. They minimize the risk of damage to goods, resulting in fewer claims and replacements. Investing in quality desiccants upfront can lead to long-term savings.


Container desiccants are essential tools in ensuring the safe transportation of goods. By reducing humidity levels and controlling moisture, they protect cargo from mold, mildew, and corrosion. Whether you choose horizontal or vertical desiccants, gel or liquid desiccants, proper installation and selection based on your specific shipping requirements are crucial. Invest in high-quality desiccants from reputable suppliers to ensure effective moisture control and protection of your valuable cargo.
