Desiccant Package
Rightfully the size of the container where the goods are stored determines the amount of desiccant needed due to each type of desiccant has its own absorption rate. However the packaging of the desiccant also plays an important role here. The packaging also known as the cover stock of the desiccant requires a certain level of adsorption rate and the dusting requirements where it would not allow dusts go into the packaging and contaminates the product.
The type of packaging material is very important to determines the efficiency of the desiccant adsorption rate. For example if the products required to be packed in a non-dusting cover stock where the transmission rate of water vapor is very low, it may cause another problem of absorption of the desiccant greatly affected, most probably the desiccant used in this case is not efficient or the absorption rate is lower.
A new type of material has been invented in the desiccant packaging industry known as Spunbonded, it is a type of polyethylene material in high density form. This Spunbonded material cannot be used alone as the packaging material. Normally it is combine with a waxy paper for the whiteness effect, some even bonded with special graded aluminum foil to give the cover stock extra strength.
The benefit of using this polyethylene product is retain the dust from going inside the packaging as well as protecting it from stains, mildew and mold growth. At the same time, the adsorption rate of the desiccant used will not be reduced due to the use of this type of packaging.
