Desiccant Bags are desiccants that are packaged in porous materials such as Kraft Paper or Tyvek. Desiccant packs absorb moisture, odors and chemicals to preserve and protect your products such as semiconductors, electronics, cartons of food, and all types of machinery. Products in nearly every industry require protection from moisture. Desiccant bags and packets are effective ways to control moisture exposure and prevent rust, mold, and mildew. Bags are available in sizes ranging from 1/6 unit to 80 units (5 ½ grams to 2,640 grams).
