An anti-condensation bag or desiccant bag is a bag made from a synthetic fleece that is filled with small silica gel beads . The bags are added to the packaging of some dry foods such as nori algae to prevent softening due to moisture absorption or to inhibit the growth of microbes due to low humidity .
Function and purpose
The purpose of the anti-condensation bag is to protect a product from damage, condensation or humidity. The anti-condensation bag is usually enclosed in the packaging of electronic devices such as computers or TV cameras, so that these moisture-sensitive products are not damaged by condensation that occurs when the temperature changes . The bag is able to absorb the humidity in the packaging. The water remains in the silica gel beads.
These bags are also used in the export of automobiles to avoid mold or odor problems caused by condensation.
Anti-condensation bags whose silica gel content is saturated can be regenerated by heating them out. To do this, the silica gel can be dried at 110–120 ° C. If the anti-condensation bag is made of plastic, synthetic fiber, or is sealed with adhesive, these materials represent an upper limit for the heating temperature. This is then depending on the material to a suitable temperature, e.g. B. 80 ° C to reduce.
