Do you need to look at thickness when choosing non-woven fabrics?
The increase in the thickness of the non-woven fabric means that the weight per unit area increases, and the corresponding strength also increases, but due to its own structural characteristics, the increase in thickness does not mean an increase in the barrier properties of microorganisms. For example, when a thickened non-woven fabric is used, the increase in the weight of the spunbond layer cannot effectively increase its antibacterial performance. Only when the pore size of the key filter layer (ie, the meltblown layer) can effectively filter the invasion of microorganisms and dust, its resistance Bacterial properties meet the requirements. As the thickness increases, the air permeability of the packaging material will also be affected, and the probability of wet packs will also increase.
