It is useful and neccessary to choose a correct packaging material when buy silica gel desiccant. To choose a correct paper, you need to care some factors below.
1. Permeability .
permeability is the most important feature . Good permeability means the desiccant has a better adsorption ability. If air tight, it means moisture adsorption slowly, thus affecting the silica gel desiccant moisture control ability .
2. Safety
Speaking of desiccant safety, we should consider the strength, sealing and other factors. In application, the packaging papers play the role of barrier ,making sure there is no leakage of the adsorbent；no direct contact with products, especially foods, medcines and other products. So ,if you use inferior packaging paper, there is a risk of product quality, safety.
3. Special need
In some situation,we need special peformance of desiccant. For example , the product must not direct contacting with dust， we have to select an anti-dust packaging paper. And, in rich oil contained foods, we have to consider anti-oil material ， because much oil will block the pores ,affecting the adsorption capacity.
4. Cost performance
We have to consider its cost performance when choosing a correct type material. If you do not have so much budget, we have to combine its price with safety,effectiveness on actual demand. After comparing all the factors ,we will make the conclusion.
