Raw Material

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.

Packing Material

This chain type silica gel desiccant mainly adopts Ava paper or DuPont tyvek paper as the wrapping material, both wrapping materials have good tensile strength and are suitable for making chain type desiccant. Ava paper is a kind of material with very good air permeability. The material is translucent, and if the internal raw material has added indicator, this kind of package material can easily observe the color change of the indicator. Because the material is translucent, it can be used to print a warning message on the inside, and the printing ink will not directly contact the product, so it can be used for the packaging of food and drug. DuPont tyvek paper is high strength, light weight, tough and tear resistant. It has strong permeability and does not re-infiltrate. It is moisture-proof, anti-static and non-sticky to dust. It is non-toxic and harmless, neutral and non-moldy. It does not work on most acid and alkali substances. It can print neutral version, Chunwang trademark version, and also support customers to customize their own layout.

Silica gel desiccant is non-toxic, tasteless, non-corrosive, non-pollution and with low price. It can provide different specifications in the range of 1g-2000g to be applicable to different industries and different application scenarios. Chain type silica gel desiccant mainly provides 1g/2g small package specifications, which can be automatically put into the package by the package throwing machine to save the cost of manual putting, mainly used in food, medicine, diagnostic reagents and other industries.
