Requirements and standards for medical packaging bags

　　The composition of the medical sterilization paper plastic packaging bag is paper+plastic composite film, which is used to package the medical devices to be sterilized and belongs to the initial inner packaging of the product. Generally, the sterilized paper plastic packaging paper needs to print the relevant information of the manufacturer or product of the medical device.

　　According to the regulations, the printing area shall not exceed 50%. The aliases include sterile packaging bag, sterile packaging bag, medical reagent packaging bag and medical paper plastic bag.

　　The medical packaging bag of medical composite film can be applied to EO ethylene oxide and high-temperature steam respectively, such as high-temperature steam sterilization or hospital medical device sterilization, and can be used to contain articles to be sterilized.

　　PET (polyester)/PE (polyethylene) colorless and transparent medical composite film should not be used for high-temperature sterilization. Because PE itself cannot withstand high temperatures and its glue cannot withstand high temperatures, it is not recommended to use PET (polyester)/CPP (polypropylene) for irradiation sterilization, because the irradiation rays will cause the aging and embrittlement of CPP, and may also precipitate harmful halides.

　　Generally, products are put into bags in the clean workshop. Then, seal the bag with a heat sealing machine and put it into a carton for sterilization. Due to different materials, the shelf life of bacteria is generally divided into 1 year, 3 years and 5 years, all of which have been verified by aging. In this way, the medical supplies in the bag can be sterilized before transportation and storage until opened by the hospital nurse.

　　Function principle: With the semi permeability and antibacterial property of packaging materials, sterilization gas such as EO ethylene oxide or steam can penetrate to achieve sterilization effect, preventing bacteria from entering the sterilized paper plastic packaging bag again. During the storage, transportation and validity period that meet the requirements, the bag shall be kept sterile until the sterilized paper plastic packaging bag is opened. Keep the product sterile. The package shall be free from air pollution, fiber breakage, dust, other foreign matters and microorganisms. Therefore, the packaging shall ensure that the packaging materials are not damaged; Completely sealed, with proper peeling strength, no penetration, no blasting, and clean peeling.
