Because the raw materials used in the diapers themselves have an odor, plus the process of producing diapers also undergoes various processes and disinfection procedures, so it is only normal that the final product produced has an odor. For example, the slight smell of disinfectant is the smell left by various sterilization and disinfection procedures during the production of diapers, and the diaper production line will be cleaned and disinfected regularly. Therefore, if the diapers are packed directly without ventilation, there may be some residual disinfectant smell which is normal. Before use, the amount can be opened in advance to let the diapers in a ventilated place to dry for a while, the smell of disinfectant will disappear.
