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.
Also known as: Desiccant pouches, Moisture absorber packets, Anti-moisture packets
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.
| Silica Gel Type | Color Change | Eco-Friendly | Best Use |
|---|---|---|---|
| White Non-Indicating | No | Yes | General packaging, electronics |
| Blue Indicating | Blue to Pink | No | Industrial monitoring |
| Orange Indicating | Orange to Colorless | Yes | Food, pharma, exports |

Frequently Asked Questions (FAQs) – Silica Gel Pouches
How many silica gel pouches are needed per carton?
The required number of silica gel pouches depends on carton size, product sensitivity, storage duration, and humidity levels. Typically, 25g–50g is used for small cartons, while export or heavy-duty packaging may require 100g to 500g pouches.
Are silica gel pouches safe for food and pharmaceutical packaging?
Yes. White non-indicating and orange indicating silica gel pouches are non-toxic and safe for food and pharmaceutical packaging when used as desiccants. They should not be consumed or placed directly inside edible products.
How long does a silica gel pouch last?
Silica gel pouches remain effective until they reach moisture saturation. Depending on humidity and exposure, they can last from a few weeks to several months. Indicating silica gel helps visually identify saturation.
Can silica gel pouches be regenerated and reused?
Yes. Silica gel pouches can be regenerated by heating at 110°C–120°C for 1–2 hours. Once dried, they can be reused multiple times if the pouch material remains intact.
Do you supply custom-size or branded silica gel pouches?
Yes. Seyon Enterprises supplies silica gel pouches in custom sizes, GSM fabrics, and OEM-branded packaging for bulk and industrial requirements.
