White Silica Gel Pouch

About White Silica Gel Pouch

White silica gel pouches are desiccant sachets of moisture-absorbing non-indicating white silica gel beads. These pouches are used to safeguard products from the damaging effects of humidity, including corrosion, mold, and spoilage. The silica gel contained is composed of amorphous silicon dioxide and has the capacity to absorb 30-35% of its weight in moisture under conditions of high humidity. Unlike color-changing silica gel, white silica gel won't color change with moisture absorption, which is ideal for use in areas where it is not necessary to see when it is saturated. The packets are usually made from breathable materials such as non-woven fabric, Tyvek, or paper, which permit moisture vapor through while holding the desiccant securely within. Found in a variety of sizes from 0.5 grams to 1 kilogram, white silica gel pouches are often utilized in electronics, pharmaceutical, textile, and machinery packaging for shelf life extension and product freshness maintenance.
