Silica gel packets contain silicon dioxide in a translucent granular form. It has a high porosity allowing it to absorb excess moisture in confined spaces. Depending on the conditions of relative humidity and temperature to which silica gel is exposed, is more or less able to absorb moisture. Thus, at high temperatures the absorption capacity decreases. Silica packets are desiccant bags widely used to protect products from damage by moisture, during transport and during storage thereof. With the introduction of desiccant silica gel within the packaging prevents possible degradation or deterioration of those likely to have changes in the presence of ambient moisture products. Silica gel sachets are definitely an ideal place to ensure the quality of goods during shipping or stockpiles in warehouses, can guarantee the condition of the product upon arrival at destination or after their stay in stock product. Silica gel is a non-toxic and non-corrosive drying agent, used for many applications in several sectors.
