The air permeability of the outer package was judged by testing the moisture absorption rate of the deodorant desiccant.
Sample 1: Deodorant desiccant, the raw material is modified spherical activated carbon, O-cloth packaging, raw material is 25 g/bag, product number is 25-101 BO160-007. The picture is as follows:
Sample 2: Deodorant desiccant, the raw material is modified spherical activated carbon, DuPont paper packaging, 15 g / bag, product number 15-101AG120-009. The picture is as follows:
The deodorizing desiccant of two different packaging materials with modified spherical activated carbon as raw material, the moisture absorption rate of deodorizing desiccant packaged with SMS non-woven fabric is 15.05% in the same time, except DuPont paper packaging. The moisture absorption rate of the stinky desiccant was 14.50%. It can be seen that the SMS nonwoven fabric has good gas permeability.
