Silica gel desiccant is a kind of highly active adsorbent material, which is the most commonly used desiccant. It belongs to amorphous substance, its chemical molecular formula is mSiO2.nH2O. it is insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and is a very safe, physical adsorption type desiccant, which can absorb and lock moisture through its own internal microporous structure (moisture absorption rate can reach 30%), and does not damp decompose after absorbing moisture. It has the characteristics of non-toxic, tasteless, non-corrosive and non-polluting, so it can be in direct contact with any articles.
Aihua paper is a very breathable material. The material is semi-transparent, and it is easy to observe the color change of the indicator if there is an indicator added to the internal material. Because the material is translucent, it can be printed with a warning message on the inside, and the printing ink will not directly touch the product, and it is produced according to food-grade standards, so it can be used for food packaging. It can be printed in neutral version, Chunwang trademark version, and also support customers to customize their own layout.
It is non-toxic, tasteless, non-corrosive, non-polluting and low price, etc. Food grade silica gel desiccant is commonly used in nuts, fried food, candy, cookies, snow cakes, candied fruit, tea, puffed food, dried fish, shredded fish, seaweed, dried agricultural products, health food and other food with low water content.
RoHS, DMF, halogens, PAHs, o-benzene, SVHC, heavy metal detection, etc.
