What are anti-humidity sachets? Moisture-wicking sachets have only one purpose: to absorb water. They are often found in food or clothing packaging. They protect your goods from moisture and corrosion.

Desiccant moisture absorber are available in many sizes. There are small sachets a few centimeters wide that would go almost unnoticed. But larger bags also hang on a chain in a container. They keep the humidity inside the container low enough to transport your goods safely by sea or rail.

How do Desiccant moisture absorber work? 

These sachets' dehydrating properties are attributed to 2 important minerals: clay and silica gel.

Clay is the most economical and environmentally friendly desiccant. It is a 100% natural substance and, therefore, non-toxic. The clay used for these purposes has a strong ability to absorb moisture. Unlike silica gel, clay also protects against a second enemy: corrosion. Therefore, clay is most often used in such sectors:

·         the mechanic,

·         sea ​​transport.

Silica gel, conversely, is a desiccant artificially developed and patented in 1919 in Baltimore, Maryland, United States. A fine grain of silicon dioxide rather than a gel. Silica gel is currently the desiccant with the best absorption properties on the market. Even when these moisture-wicking pouches are saturated, they stay dry to the touch. Silica gel is used for sending, among other things:

• textile,
• pharmaceutical products,
• foodstuffs,
• electronic products.

How to use them?

To prevent condensation, anti-humidity sachets should match the dimensions of the box and the product they contain. To ensure the proper functioning of the desiccant, it is also advisable to use a film or an airtight bag. Clay and silica gel desiccants are also reusable. So you can use the sachet from one packaging to another.

If it still happens that a sachet of silica gel is still wet, simply place them in the oven in a suitable dish at +120 to +150°C for 1 hour. Its absorption properties will then be just like new!

But where else? 

We have already discussed the use of desiccants in the packaging industry. But their first applications were elsewhere. Silica gel, for example, was first used on a large scale during World War II. The US military used it at the time to keep penicillin dry. But history has taught us that they have many other uses:

• Eliminate bad odors in a room.
• Keep the clothes in your closet dry.
• Avoid condensation on windows.
• Prevent the growth of bacteria in the bathroom or a sports bag.
• Keep food fresh longer.
• Preserve old photos.
