How container desiccants work and their types and benefits
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.
- 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.
- 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.
- 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.
- 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.
