Although the disposable non-woven fabric has a great barrier effect on microorganisms, it is not easy to be affected by secondary pollution. The sterilization effective time limit is 6 months, and the resistance to penetration is strong, and there is no wet bag phenomenon. It is more advantageous than other sterilization packaging materials in terms of physical properties, sterilization compatibility, sterilization quality, and storage efficiency. However, its puncture resistance is poor, it is easy to be broken as a separate packaging material, and it is most likely to cause puncture exposure when it is packaged as a sharp device, which seriously affects the quality of sterilization. Therefore, our hospital generally uses cotton cloth as the inner layer packaging and non-woven fabric as the outer layer packaging, and the effect is very good.
