What Is Sili Pak?

Silica Gel desiccant packets provide an economic and effective way of protecting against moisture damage during transit and storage. The bags are filled with non-indicating beaded silica gel desiccant with capacities ranging from 2 gram to 500 grams.
Silica gel desiccant is the most common type of moisture absorbent in the market and it is widely used for various kinds of industries.The protection against moisture is achieved by sealing the product in a suitable air tight bag or container together with the appropriate sized desiccant bag.

Characteristic

1. Moisture absorption rate over 40% at 25℃，RH90%
2. No physical forms changed after moisture absorbing, nontoxic, no harm, no pollution;
3. The particles are uniform and surface dry, and there is no obvious change in appearance before and after use;
4. Reusable, after moisture absorption, dry and renewable;

Packing Material

Laminated Non-woven & Tyvek
Two material can be choose:
1.Good breathability;
2.Easy heat-seal;
3.Excellent resistance to dust;
4.Good Printing.

Tyvek bags are made from high density polyethylene fibers, making them extremely tear-resistant. In addition, Tyvek is lightweight, flexible, smooth, low-linting, and is resistant to water, chemical abrasion, and aging.
