Desiccant Packs for Food

Food silica gel desiccant is commonly used in food packaging. If you are careful, you will find that some desiccants are not the same. Some desiccants are transparent beads, some are white irregular blocks, and some are brown beads. The ingredients of different desiccants are totally different. There are three kinds of food desiccants: silica gel desiccant (transparent granule), lime desiccant (white block) and mineral desiccant (brown bead).

At present, the desiccant used more for food is silica gel desiccant, because silica gel desiccant is a kind of physical adsorption desiccant instead of chemical reaction moisture absorbing desiccant, and silica gel is the desiccant material recognized by FDA that can be in direct contact with food and drug. Compared with other desiccants, silica gel desiccant is better to be used in food moisture-proof. In addition to the above factors, silica gel desiccant also has strong moisture absorption ability, strong adsorption performance, and it will not melt even if all the silica gel desiccant is soaked into water. It has the characteristics of tasteless, non-corrosive and non-polluting, and will not be absorbed by human body even if it is mistakenly eaten.

The performance of food grade silica gel desiccant

• Food grade silica gel desiccant is a kind of environmentally friendly silica gel desiccant, non-toxic, odorless and degradable;

• Soft, good elasticity, kink resistance and no deformation;

• No cracking, long service life, cold resistance and high temperature resistance;

• Has higher tear strength and superior electrical properties;

• It will not turn yellow when placed at room temperature, no frost, no whitening, no fading, no scale and no peculiar smell in the water for a long time;

• Belong to food grade, more safe and secure
