What are humidity packs, and how do they work?
Humidity packs, also known as desiccant packs or humidity control packs, are small, self-contained pouches or sachets containing a desiccant material designed to regulate and control the relative humidity (RH) levels within a specified environment. These desiccants absorb excess moisture or release moisture as needed to maintain a specific RH level, thereby preventing the degradation or spoilage of stored goods. The packs are commonly used in various industries, including food, pharmaceuticals, electronics, and textiles, to preserve the quality and integrity of sensitive products during storage and transportation.
Humidity packs work through the principles of adsorption and desorption. When the surrounding environment has elevated humidity, the desiccant material within the pack adsorbs the excess moisture, effectively lowering the RH level. Conversely, when the environment is drier, the desiccant releases moisture to maintain an optimal humidity level, thereby stabilizing the storage conditions.
