Walter Albert Patrick's 1919 patent for synthetic silica gel enabled large-scale production, making desiccant bags widely available for industrial use.
Desiccant bags function by absorbing moisture from the surrounding air. The materials inside the bags, such as silica gel or clay, have a high affinity for water molecules. When placed in an enclosed space, the desiccants attract and trap water vapor, reducing humidity levels. This process prevents moisture-related issues like rust, mold, or product degradation. However, desiccant bags need replacement once they reach their saturation point.
Desiccant films are thin, flexible sheets embedded with moisture-absorbing materials. Unlike desiccant bags, these films integrate directly into product packaging. They are commonly used in industries requiring compact and efficient moisture control solutions, such as pharmaceuticals and electronics. The materials used in desiccant films include silica gel and molecular sieve, which ensure effective moisture absorption.
Desiccant films work by continuously absorbing moisture from the air within a sealed package. The embedded desiccants, such as silica gel, interact with water molecules, trapping them within the film's structure. This mechanism ensures a controlled environment, protecting sensitive products from humidity. Desiccant films are particularly effective in flexible packaging, where space-saving solutions are essential.
