Polyester Desiccant Packaging Material Non Woven Fabric

By adjusting the weight, process and post-processing, the diverse needs of different desiccant types and different application scenarios (from ordinary industrial products to high-demand electronics, food, and medicine) can be met.Polyester (PET) non-woven fabric is a very common and excellent choice for desiccant packaging materials.

Our advantages

Gram weight: Different gram weights can be selected according to needs (common range is 15gsm to 60gsm or higher). The higher the gram weight, the better the strength and the stronger the dust resistance, but the air permeability will decrease slightly (need to be balanced).

Color: White, blue (commonly used for indicating silica gel) or other colors can be produced.

Performance: The air permeability, strength, softness, etc. can be optimized by adjusting the fiber type, bonding process, post-treatment, etc.

Composite: It can be composited with other materials (such as PP non-woven fabrics, breathable films) to meet special needs (such as ultra-high dust resistance, specific air permeability).

Typical applications

Silica gel desiccant bag: It is the main application form.

Montmorillonite desiccant bag: It is also applicable.

Calcium chloride desiccant bag: Special attention should be paid to the deliquescence resistance and strength of non-woven fabrics (calcium chloride will deliquesce after absorbing moisture).

Mineral desiccant bag.

Container drying strips/bags.

Moisture-proof packaging used in many fields such as electronic products, electrical appliances, shoes and clothing, food (must meet food contact requirements), medicines, equipment, military industry, transportation (container drying), etc.

Considerations when selecting materials

Air permeability: The amount of water vapor passing through a unit area of ​​material per unit time. Directly affects the drying speed. The appropriate range needs to be selected according to the type of desiccant, moisture absorption requirements and ambient humidity.

Dust resistance: Usually evaluated by dust testing (such as vibration screening method) to ensure that the desiccant powder does not leak out.

Tensile strength & tear strength: Ensure that the package does not break under stress.

Gram weight: Affects strength, dust resistance and cost.

Heat seal strength: Ensure that the edge of the desiccant packet is firmly sealed and will not crack during use.

Cleanliness: Especially important for highly sensitive products.

Chemical compatibility: Ensure that there is no adverse reaction to long-term contact with specific desiccant.

Compliance: For applications such as food and medicine, materials must comply with relevant regulations (such as FDA, EU 10/2011, etc.).
