Desiccant Capsules

Desiccant capsules are safe, non-toxic, low-dusting sorbent cartridges designed to deliver high moisture and odor adsorption capacity in a compact format. This style of desiccant container was once widely used and was commonly associated with the Dricap® brand. Available in several sorbent types, desiccant capsules help protect packaged products from moisture-related damage such as caking, mildew growth, fermentation, potency degradation, and shortened shelf life. Desiccant options include silica gel, indicating silica gel, molecular sieve, and indicating molecular sieve formulations.

What are desiccant capsules used for?

Plastic desiccant capsules are used in a broad range of drying and moisture-control applications, including pharmaceuticals, diagnostic packaging, electronics, optics, laboratory services, and other technical industries. Their low-dusting construction and sonically welded end caps help eliminate many of the contamination and particulate issues associated with traditional non-plastic desiccant canisters.

Desiccant capsules are engineered for easy integration into existing packaging operations. Their dimensions are designed to fit standard dispensing equipment, minimizing the need for costly production line modifications. Manufactured from FDA-grade High Density Polyethylene (HDPE), these canisters typically do not require additional material stability testing and provide reliable adsorption performance to help safeguard packaged products. They are also compatible with irradiation processes, allowing for final product sterilization when required.

Proper handling and storage are essential to maintaining desiccant performance. Depending on environmental relative humidity (RH), desiccants can lose up to 25% of their adsorption capacity within an hour or less of exposure to ambient air. To maximize effectiveness, desiccants should be stored in properly sealed moisture barrier packaging and handled only under controlled conditions.

For pricing information, please contact us with the specific desiccant type and required quantity. Accurate pricing depends heavily on order volume, which can vary significantly between industries and applications. Typical customer usage ranges from approximately 800 units per month to more than 550,000 units per month.

To support product testing and evaluation, we offer a variety of smaller package quantities. These evaluation packages are particularly well suited for pharmaceutical, biomedical, and electronics companies because they are lot coded for traceability and sealed in secure moisture barrier packaging comparable to or exceeding production-level packaging standards. As a result, they provide a far more representative evaluation sample than loose poly bag samples typically distributed for preliminary review.
