Anti-humidity Silica Gel Desiccant Sachets
Silica gel desiccant is a kind of small sachet desiccant with fine hole silica gel as raw material.The principle of drying is to remove the water molecules in wet substances by adsorption, that means through the particles of the solid surface, to adsorb the water molecules in various gases and liquids, and pack on the surface of solid material.
Anti-humidity Silica Gel Desiccant Sachets can packed by 1gram, 2 gram, 5gram, 8gram, 10gram, 15gram,20gram, 25gram, 50gram,100gram, 200gram,500 gram, 1000 gram, etc. (OEM service is welcome).
Anti-humidity Silica Gel Desiccant Sachets get different packing type:Back seal,Three sides seal,Four sides seal. And the packing material also have many choice, for example:Composite paper,Non woven paper,Filter paper,Tyvek paper,etc.
1: Composite paper is also called laminated paper. The strength is normal, and the air permeability is poor ,so that the absorption of moisture is slow.Composite paper is not suitable for electronic products.
2: Non-woven paper has good strength, better air permeability and toughness. But it is easy to leak powder, when it’s used for packaging montmorillonite.
3:Filter paper(breathable paper) can be used for small size silica gel desiccant packaging, which is not fit for packaging montmorillonite,because of insufficient strength and easying leakage of powder.
4: Tyvek paper, it is the best material for all kinds of desiccant packaging, with good air permeability, enough strength and beautiful printing effect .And it still have other nice characteristics, like anti - static, good air permeability, anti - chemical, dust-free design, excellent weather resistance,etc.Of course ,the price is the highest.
