»Moisture damage is one of the most underestimated threats in packaging today. Most people focus on choosing the right desiccant, but how you store and handle it before it ever enters a package is just as critical to its performance.,«
To walk us through the essentials of proper desiccant storage, handling, and use, we spoke with Tatiana Berro, Territory Sales Manager and Moisture Control Expert, Adsorbents Americas.
What is a desiccant and why does it matter for packaging?
A desiccant actively removes moisture from inside a sealed package, protecting products across countless industries, including electronics, pharmaceuticals, automotive parts, foods, and nutraceuticals, from humidity damage. It works by attracting and adsorbing moisture from the air inside the package before it can reach your product. The concept is simple, but how you handle it before it ever enters that package makes all the difference.
Which type of desiccant should I choose?
The right desiccant depends on your humidity environment and product sensitivity. There are three main types used in packaging applications, and each has a distinct performance profile
Brand Desiccant Type Source Best for Key Characteristic Desi Pak Bentonite Clay Natural mineral Moderate-to-low humidity Slower adsorption rate reduces risk of premature saturation during handling Sorb-It Silica Gel Synthetic Moderate-to-high humidity Retains adsorption performance at elevated temperatures Tri-Sorb Molecular Sieve Synthetic zeolite Very low humidity Most aggressive moisture removal, requires immediate transfer to application upon opening When in doubt, consult a moisture-control expert before making your final selection.
How do I know how much desiccant to use?
This is where many packaging decisions can sometimes go wrong, either using too much desiccant out of caution or too little to cut costs, for example. The right amount typically depends on factors such as the internal volume of your package, the moisture sensitivity of your product, the moisture vapor transmission rate of your packaging materials, humidity conditions at the time of sealing, and your required shelf life.
These variables interact in ways that are easy to miscalculate. Clariant offers expert support from global representatives and practical tools, including desiccant and package calculators, to help you make informed decisions for your specific application.
