Capsules & Cannisters

Desiccant canisters are rigid, drop-in moisture-control components used inside bottles or other healthcare packaging to help maintain product stability and extend shelf life. They are especially useful for pharmaceutical and nutraceutical products that may physically or chemically degrade when exposed to humidity. Royco Packaging offers canisters that can be inserted automatically during packaging, avoiding the cutting step associated with continuous packet strips. The rigid format also supports hopper feeding and high-speed insertion on standard equipment. Depending on the application, canisters may contain silica gel, molecular sieve, activated carbon, or combinations of sorbents. Royco can help customers match the canister type to the required moisture or odor control.

Royco Packaging offers desiccant canisters with several active materials. Silica gel is available for broad moisture-control applications, while molecular sieve is used when stronger adsorption or lower humidity is required. Activated carbon can be used independently or combined with silica gel when odor adsorption is also important. The correct material depends on the product’s moisture sensitivity, desired shelf life, package headspace, storage conditions, and any odor-control requirement. Because these canisters are designed for healthcare packaging applications, Royco can work with pharmaceutical or nutraceutical customers to select a sorbent system that fits both the stability objective and the intended high-speed packaging process.

Royco Packaging states that its pharmaceutical desiccant canisters are compliant with applicable U.S. FDA and European Union requirements for pharmaceutical use and with USP <670> requirements for pharmaceutical desiccants. This makes the canister line appropriate for regulated healthcare packaging where material suitability and product stability are important considerations. Compliance does not remove the need for the device or drug manufacturer to validate the complete packaging system for its specific product, shelf life, and regulatory pathway. Royco can provide product information and help customers select the appropriate canister size and sorbent. For formal submissions or quality documentation, customers should request the exact supporting certificates needed for the chosen product.

Royco Packaging lists standard desiccant canister sizes of 1 gram, 2 grams, and 3 grams. These compact rigid formats can be selected according to container volume, product moisture sensitivity, expected shelf life, and the adsorption capacity needed inside the package. Royco also notes that standard and customized canister products are available, so projects that fall outside typical requirements can be discussed with the packaging team. Choosing the correct size is not simply a matter of bottle dimensions; it also depends on barrier properties, initial product moisture, storage conditions, and the active material used. Royco can help customers identify an appropriate configuration for pharmaceutical or nutraceutical packaging.

Yes. High-speed insertion is one of the main advantages of rigid desiccant canisters. Royco Packaging explains that the canisters can be hopper fed and inserted on standard automated packaging equipment, which can simplify production compared with packet formats that may require cutting or separation before insertion. Their robust construction is intended to support continuous handling on packaging lines while placing a controlled amount of sorbent into each container. Royco offers canisters with silica gel, molecular sieve, activated carbon, and combinations, allowing the moisture- or odor-control function to be matched to the product. Customers should confirm canister dimensions and equipment compatibility during line setup or validation.
