Why should the packaging of sterile medical devices be tested for the permeability of paper-plastic bags?
If it is sealed, ethylene oxide gas is not easy to penetrate during sterilization, and it is not easy to analyze when it penetrates.
If the air permeability is too good, it means that the pore size is large, bacteria and other microorganisms can easily enter the package, causing pollution of medical devices, so it is necessary to test the air permeability of the package.
