The manufacturing process starts with selecting the appropriate desiccant material, such as silica gel, activated alumina, molecular sieves, or clay, based on its moisture-absorbing properties. The packaging material is also chosen at this stage, often using Tyvek, cotton, or non-woven fabrics, which are permeable to moisture but durable enough to contain the desiccant.

In this step, the desiccant material is measured and dispensed into the packaging material. Automated filling machines are typically used to ensure each bag contains the precise amount of desiccant, ensuring consistency across all bags. The packaging material is then prepared for sealing, often by folding or aligning the edges.

The bags are sealed using heat sealing machines, which apply heat and pressure to create an airtight seal. This step is crucial to prevent the desiccant from spilling out and to maintain its moisture-absorbing properties. After sealing, the bags undergo a quality check to ensure there are no defects in the seal.

Finally, the sealed desiccant bags are grouped and packaged into larger containers for shipment. Each package or individual bag is labeled with important information, such as the type of desiccant, net weight, manufacturing date, and usage instructions. Proper labeling ensures that users can easily identify the product and understand how to use it effectively.
