Molecular sieves are porous crystalline aluminosilicates, a synthetic desiccant that has a very strong affinity for moisture molecules. The distinctive feature of the molecular sieve structure, as compared to the other desiccants, is the uniformity of the pore size openings in the crystal lattice structure.
There is no pore size distribution with molecular sieves. As part of the manufacturing process, the pore size on the molecular sieve particles can be controlled and is available in a variety of sizes. This feature allows the selection of a molecular sieve product which can adsorb water, yet exclude most other molecules, such as volatile organics, which might be present in the package.
The selective adsorption characteristics of molecular sieves can be useful when it is necessary to dry a package without removing other desirable compounds from the system. Molecular sieve can hold moisture to temperatures well past 450°F (230°C), and because of its high affinity for moisture, molecular sieve is able to bring the relative humidity in packages down as low as 10% RH.
At Protective Packaging Corporation we have spent the last quarter century researching the most effective packaging materials and systems available. Whatever the humidity control packaging requirements, we have the optimal solution to meet your needs.
