How container desiccants work and their types and benefits

Container desiccant


Container desiccants are an essential packaging component for many products, including electronics, pharmaceuticals, and food items. Desiccants are materials that absorb moisture, and when used in packaging, they help maintain the contents' quality and safety. This blog will discuss how container desiccants work, the different types of desiccants, and the benefits of using desiccants in packaging.

How Do Container Desiccants Work? 

Container desiccant work by absorbing moisture from the air. Desiccants contain a hygroscopic material, which means they can absorb water molecules from the air. When the desiccant absorbs moisture, it is trapped inside the desiccant and prevented from coming into contact with the contents of the package.

Types of Desiccants

Several types of desiccants are used in packaging, including silica gel, clay desiccants, molecular sieve desiccants, and calcium oxide desiccants. Each type of desiccant has unique properties that make it suitable for different types of packaging applications.

  1. Silica Gel Desiccants are one of the most commonly used types. They are made from silicon dioxide and are highly effective at absorbing moisture. Silica gel desiccants come in various forms, including beads, packets, and canisters. They are particularly useful for moisture-sensitive products, such as electronics and pharmaceuticals.
  2. Clay Desiccants Clay desiccants are made from a type of clay called bentonite, which has a high affinity for water molecules. Clay desiccants are typically used in larger packaging applications, such as shipping containers, due to their large surface area. Clay desiccants are also relatively low-cost, making them a popular choice for packaging.
  3. Molecular Sieve Desiccants Molecular sieve desiccants are desiccants that use a special material to trap moisture molecules. These desiccants are highly effective at absorbing moisture and are commonly used in packaging products that require precise moisture control, such as pharmaceuticals and food items.
  4. Calcium Oxide Desiccants Calcium oxide desiccants are made from quicklime, which is highly effective at absorbing moisture. Calcium oxide desiccants are typically used in applications where the moisture content needs to be reduced to a very low level, such as in the protective packaging of electronic components.

Benefits of Using Desiccants in Packaging

The use of desiccants provides several benefits, including:

  • Protecting the contents from moisture damage: Desiccants help to protect the contents of the package from moisture damage, which can occur due to changes in temperature and humidity. By absorbing moisture, desiccants prevent moisture from coming into contact with the contents of the package.
  • Maintaining product quality: Desiccants help to maintain the quality of the contents of the package by preventing moisture damage. This is particularly important for moisture-sensitive products, such as electronics and pharmaceuticals.
  • Increasing shelf life: By preventing moisture damage, desiccants help to increase the shelf life of the contents of the package. This is particularly important for food items, which can spoil quickly if exposed to moisture.
  • Reducing product spoilage: Desiccants help to reduce the risk of product spoilage by absorbing moisture, which can cause products to deteriorate over time. This is particularly important for moisture-sensitive products, such as food items and pharmaceuticals.
