Repeated folding can form a long curved path to prevent microorganisms from 'easily' entering sterilization. In the bag, 2 layers of non-woven fabrics cannot be used for 1 packaging.

8. 'Tyvek' non-woven fabrics should be selected for low-temperature plasma of hydrogen peroxide, and medical non-woven fabrics containing plant fibers cannot be used, because plant fibers will absorb hydrogen peroxide.



9. Although medical non-woven fabric is not a medical device, it is related to the sterilization quality of medical device. The quality of medical non-woven fabric as a packaging material and the packaging method are very important to ensure the sterility level.
