1. What Are Silica Gel Pouches?

Silica gel pouches are small sachets filled with moisture-absorbing silica gel beads or crystals. The pouch material may be non-woven fabric, Tyvek, paper, cotton or composite material, depending on the application.

2. How Silica Gel Absorbs Moisture

Silica gel has a porous structure with millions of micro-pores. These pores attract and hold water molecules physically (adsorption).

• Absorbs up to 30–40% of its weight in moisture
• Works even in low-humidity conditions
• Does not swell or leak like clay desiccants

3. Types of Silica Gel Used in Pouches

• White Non-Indicating Silica Gel

Economical and widely used for general packaging.

• Blue Indicating Silica Gel

Changes color from blue to pink when saturated.

• Orange Indicating Silica Gel (Eco-Friendly)

Changes from orange to colorless. Safe for food, pharma, and export use.

4. Sizes & GSM (Fabric Material)

• Non-Woven Fabric: 40–70 GSM
• Cotton Pouch: 90–120 GSM
