Uses of Silica Gel in Packaging?


When you receive your order of clothes or leather shoes or silver jewellery from any online shoppe, you must have noticed a small packet containing small, transparent beads inside it. Some of you might have even opened the packet out of curiosity to see what’s inside? Inside is Silica Gel, the most widely used material in product packaging.

Silica gel is used by most product manufacturing and packaging industries for packing their products in order to save them from moisture and even bad odour. Electronic devices, Food items, dry fruits, documents, and flowers are some of the commodities that need silica gel packing. Let us learn more about the properties of silica gel and why it is used for packaging commodities?

Silica Gel and Its Properties

Silica gel is a small bead, porous in nature. It is derived from silicon dioxide, which is normally found in sand. It is represented by the formula SiO2. Although Silica Gel is not plastic, neither is it plastic-free. Apart from its use as a packaging material, it is used in chromatography and water filtration.

  • Silica gel is desiccant- It can absorb moisture by attracting the water molecules and locking the moisture.
  • Silica gel appears like a translucent solid.

Uses of Silica Gel as a Packing Material

Silica gel is used as a packing material for various reasons.

  • To absorb moisture –  Silica gel is made from Sodium Silicate which is highly absorptive in nature. Silica gel is always packed in tiny, porous paper bags to allow water molecules to enter and as soon as they do, they get absorbed by the gel inside.
  • To eliminate odour – Have you ever experienced bad odour when you open a cardboard that was kept closed for a long time? I’m sure you hated that experience and would never want to be treated that way by any company. This happens because any product that is ever manufactured undergoes a series of physical and chemical reactions that often include treatment with chemicals. These chemicals leave a bad odour when they are packed in carton boxes, which are unopened for a long duration. Silica gel when used as a packing material, eliminates the bad odour by trapping the extra moisture from the goods.
  • To prevent the growth of molds – Changes in the weather conditions like winter, rain or increase in the humidity, provides a perfect condition for molds to grow. It is a form of fungus that grows inside a closed container when sealed from air for a long time. Silica gel is the perfect solution for preventing the growth of molds inside the packaged goods.
  • Increases the life of the product – There are food materials like cereals, biscuits, bread, vitamin supplies, and pet food that can get soggy and become unusable if something is not done to prevent the moisture from entering them. Silica gel is extremely useful in packing these kinds of goods.
