We’ve all seen those little white packets that come in the box when we buy a new pair of shoes, a bottle of vitamins, a bag or a new purse. You might be wondering what this white packet is and what is it used for? Let us discuss all these questions in this article.
These little white packets are called silica gel bags. The technical name for it is silica xerogel, but most people just call it silica gel.These bags are filled with a substance called silicon dioxide, a non-toxic inert desiccant that has the power to dry out moisture.Silica, or silicon dioxide (SiO2), is the same material found in quartz. The gel form contains millions of tiny pores that can adsorb and hold moisture. Silica gel is essentially porous sand. Silica gel can adsorb about 40 percent of its weight in moisture and can take the relative humidity in a closed container down to about 40 percent. Once saturated, you can drive the moisture off and reuse silica gel by heating it above 300 degrees F (150 C).
Many manufacturers add these desiccant packs to their new products to keep them fresh and moisture-free for the consumer.In leather products and foods like pepperoni, the lack of moisture can limit the growth of mold and reduce spoilage. In electronics it prevents condensation, which might damage the electronics. If a bottle of vitamins contained any moisture vapor and were cooled rapidly, the condensing moisture would ruin the pills. You will find little silica gel packets in anything that would be affected by excess moisture or condensation.
So, now you know why these packets are used in new products. You also knew how these bags work. Thank you for reading the article.
There are multiple types of silica gels, in white, blue or orange, for different levels of humidity and different applications. Something called food-grade silica gel used in rice bags and other edible product bags actually are less dangerous. Of course, that doesn't mean we can eat them. They are just there to absorb moisture so the stuff they are protecting doesn't get fungus on it. You can try checking out Sorbead India if you decide to go silica gel online shopping!
ReplyDeleteMoisture present in the air can settle down on the surface of goods and commodities. Due to the temperature change, this moisture that settled on the surface can convert into liquid and seep inside the packaged products This liquid can initiate a chemical reaction and damage the goods completely. Minimizing the moisture content on the surface of the product is the only way to curb this problem. Using silica gel packets inside the packaged goods will lead to absorption of moisture and longer life of the products.
