Packaging Resource Center: The Latest in Desiccants
Flow-Limiting Bottle Insert
A device fits into the neck of a pharmaceutical bottle with slots designed to allow only one pill or capsule to be dispensed. The Flow-Limiter restricts the amount of product that can be released, avoiding spillage and potential exposure to microbes, pathogens, or other contamination. Molded with Advanced Desiccant Polymer, the device eliminates the need for a drop-in desiccant. The Flow-Limiter can be designed to the dimensions of a particular pill and bottle size and specific desiccation needs. Süd-Chemie Performance Packaging, New Milford, CT; 800/966-1793; www.s-cpp.com.
A standard base resin in a sorbent-material compound can be molded into the structure of packaging components and materials. DryKeep desiccant technology, licensed from Sasaki Chemical of Kyoto, Japan, works in rigid and flexible applications. Moisture bonds to the material and will not be rereleased; its crystal absorption exceeds the reaction ratios of standard physical and chemical platforms. The material maintains equilibrium of moisture at 30–40% relative humidity. Time-release properties allow for extended use. TricorBraun, St. Louis, MO; 314/569-3633; www.tricorbraun.com.
