    The latest new coronavirus is intensifying, and various masks on the market are mixed.
    In addition to being confused when you can't buy a mask, we also need to pay attention to how to choose a suitable mask


    .


    Because there are many types of masks, there are not many masks that are really effective for medical grades.
    Therefore, according to different standards, the classification of masks is also different


    .

    Sterilization of masks

    Sterilization of masks

    The main sterilization methods of general medical devices are high-temperature steam, ethylene oxide, radiation sterilization, low temperature and other particles, and our medical masks use the ethylene oxide sterilization method for sterilization (commonly known as EO sterilization)


    .


    At present, there are also some attempts to use radiation sterilization in the market, but because of the material and process particularity of mask products, odors will be generated after radiation sterilization, and the molecular weight of meltblown materials will be accelerated after irradiation, resulting in aging and no protection.
    group action


    .


    In addition, the produced masks are sterile during transportation and storage after sterilization.
    Sterilization uses physical and chemical methods to kill microorganisms.
    The sterility of sterile medical devices is not absolute, but only reduces the survival of microorganisms to a minimum.
    State, the current sterility probability of sterile medical devices is marked as 10-6, which is one in a million


    .


    At the same time, because ethylene oxide is a carcinogen, and disposable surgical masks, sterilization-grade medical masks, etc.
    are all sterilized with ethylene oxide, how to ensure that there is no ethylene oxide residue in the masks after sterilization , when in use, ethylene oxide can be fully analyzed, reaching the international analysis standard (the international standard is that the residual amount of ethylene oxide after analysis is less than 10ug/g), which is closely related to the air permeability of the packaging of the mask.
    Generally speaking, the polyethylene PE packaging bag used for packaging takes a long time to parse.
    If it is not handled properly, it is easy for consumers to wear masks that are not fully parsed, but it is harmful to the human body.
    Therefore, sterilization bags that really meet the outer packaging of masks are generally used.
    Paper-plastic packaging with high air permeability and a certain barrier, but disposable masks on the market are generally packaged in PE plastic bags sterilized by ethylene oxide, but they need to be stored for more than 20 days to facilitate the analysis of ethylene oxide in the bag

    As mentioned above, the ethylene oxide desorption time has a great relationship with the air permeability of the outer packaging


    .

    Due to the poor air permeability, ethylene oxide will not be able to enter the inside of the mask, thereby reducing the thoroughness of sterilization and disinfection, and at the same time, it will also cause incomplete analysis and cause ethylene oxide to remain on the mask, which inadvertently damages health


    .

    Since the presence of paper in the packaging can effectively enhance the air permeability, enhancing the thoroughness of sterilization and disinfection also reduces the possibility of ethylene oxide residues
    .
    Usually the analysis time is 7 days or even shorter, and the shortest can be completed in 2-3 days, which reduces the analysis period and has superior bacteria resistance, which can keep the mask sterile for more than three years, which is safer.
    Of course, the paper-plastic packaging is due to the packaging process.
    And more links, compared with polyethylene plastic bags, the cost is higher

    .

    At present, PE plastic bags for medical masks in the Chinese market account for 90%, and paper plastic bags only account for 10%.
    Because after the masks are sterilized, polyethylene packaging takes longer to ensure the analysis of ethylene oxide, so the flow of production and market It takes longer, but the paper-plastic packaging reduces the time it takes for the masks to leave the factory and protects the health of consumers more quickly

    .
    Therefore, if the packaging cost is reliable, the use of paper-plastic packaging can greatly increase the market supply of masks
