Hygroscopic material is a substance that has the ability to absorb moisture from its surroundings. These materials attract and retain water molecules from the environment, often resulting in changes in their physical properties, such as swelling or increased weight. Hygroscopic materials are commonly found in various industries, including packaging, where they are used for products that require moisture control to maintain quality and stability. Examples of hygroscopic materials include certain types of polymers, salts, and natural fibers.
