In domestic sterile supply centers, the packaging material commonly used at present is nonwoven, in addition to cotton. Hospitals are often concerned about the thickness (i.e., gram weight) when choosing nonwoven fabrics, so is the thicker the nonwoven fabric, the better? The answer is no.
An increase in the thickness of a nonwoven means an increase in weight per unit area and a corresponding increase in strength, but due to its own structural characteristics, an increase in thickness does not mean an increase in microbial barrier properties. For example, if a thickened nonwoven is used, the increase in weight of its spunbond layer does not effectively increase its bacteria-blocking performance. Only when the aperture of the key filter layer (i.e. meltblown layer) can effectively filter microorganisms and dust invasion, its bacteria-blocking performance will meet the requirements. The increase in thickness will also affect the permeability of the packaging material, and the probability of wet bags will increase.
Clinical use will occur after sterilization of non-woven fabric breakage phenomenon, for this breakage, mainly because the non-woven fabric after high temperature sterilization microscopic fine plastic fibers will have a certain degree of contraction, performance in the use of non-woven fabric after sterilization than before sterilization to brittle, so in the use of the process to it too much force or unreasonable pick and place method, will cause destructive damage to the packaging material, in addition to the use of edge In addition, the use of burrs and sharp instruments can also cause damage to the nonwoven. In this case, it is recommended that the clinic should pack the nonwoven loosely and gently, and use the double-layer packing recommended by the standard, which will significantly reduce the probability of breakage. If the problem of breakage is solved only by increasing the thickness of the nonwoven fabric, the probability of wet packing needs to be closely observed in addition to ensuring the bacteria-blocking performance.
