In order to track and improve the product quality, our QC Section will do the following operations.
Test the heat-sealing part of the finished desiccants, oxygen absorbers and other products to check whether the heat-sealing strength is above the standard value.

Put the desiccant into the desiccator with variety of relative humidity to determine the moisture-absorption property.

Test the oxygen absorber by oxygen concentration meter to confirm whether the oxygen absorption capacity is above the standard value.

Desiccants and oxygen absorbers are kept in the thermostatic chamber with the temperature of 25 ℃, test the properties after stipulated time.
