OPP Plastic Indicating Silica Gel Packets

These desiccant packets contain indicating silica gel (orange to green) packaged in clear perforated oriented polypropylene (OPP). OPP is durable and semi-permeable, making it ideal for applications requiring stable, long-term humidity control without over-drying.

Controlled Permeability: OPP allows for slower moisture adsorption, extending the lifespan of the desiccant. This is beneficial in environments where humidity must be managed over extended periods, such as in electronics enclosures.

Chemical and Abrasion Resistance: The polypropylene packets resist hydrocarbons, solvents, and mechanical wear, making them suitable for use in toolboxes, safes, and industrial equipment packaging where contact with oils or rough surfaces may occur.
