Can You Use Desiccants and Oxygen Absorbers Together?

Oct 06,2023 | Bond

Desiccants and oxygen absorbers serve different purposes in preserving the quality and shelf life of various products. While they can be used together in certain situations, it is important to understand their individual functions and limitations.


Desiccants, such as silica gel or clay, are used to absorb moisture and maintain a dry environment. They are commonly used to protect products from moisture damage, such as preventing mold, mildew, or corrosion. Desiccants work best in sealed containers to maintain their effectiveness.

Oxygen Absorbers

Oxygen absorbers, on the other hand, are designed to remove oxygen from a sealed environment. They contain iron powder, which reacts with oxygen to create iron oxide, effectively reducing the oxygen levels within the package. Oxygen absorbers are commonly used in food packaging to extend shelf life by inhibiting the growth of aerobic bacteria and fungi.

Using Desiccants and Oxygen Absorbers Together

In some cases, it may be beneficial to use desiccants and oxygen absorbers together, especially when preserving certain products that are sensitive to both moisture and oxygen. For example, in food packaging, using both desiccants and oxygen absorbers can help maintain the quality and freshness of the product by controlling moisture and oxygen levels simultaneously.

However, it is important to consider the specific requirements of the product and consult the manufacturer's guidelines. Some products may require specific conditions, such as modified atmosphere packaging (MAP), which involves controlling the gas composition within the package. In such cases, using desiccants and oxygen absorbers together may not be recommended.

It is also worth noting that desiccants and oxygen absorbers should be placed in separate compartments within the packaging to avoid any potential interaction between the two. This ensures that each component can perform its intended function without interference.
