Desiccant is a material that can adsorb water vapor, and it absorbs and locks the water vapor in the external environment through physical or chemical means to achieve the purpose of drying and moisture-proofing. Currently, the widely used desiccants for drying and moisture-proofing include: montmorillonite, activated mineral, silica gel, molecular sieve, and calcium chloride. For the general-purpose desiccant developed for industrial packaging, the unit of measurement is 'gram'. You can choose various adsorbents and packaging materials to meet your different needs. It has two main types: back-sealed and three-side-sealed, with a complete range of specifications from 0.5g to 1000g and an affordable price system. It can be widely used in electronic products, metal products, electromechanical machinery, daily hardware, footwear, leather, and other fields.
