The medical packaging bags of medical composite films can be suitable for EO ethylene oxide and high-temperature steam STEAM respectively, such as when hospitals disinfect medical devices with high-temperature steam or use them to hold items to be disinfected.
It is not suitable to use PET (polyester)/PE (polyethylene) colorless transparent medical composite film during high-temperature sterilization because PE itself is not resistant to high temperature, and the adhesive is also not resistant to high temperature. It is not recommended to use PET (polyester)/CPP (polypropylene) for irradiation sterilization Due to the aging and embrittlement effects of radiation on CPP, harmful halides may also precipitate.
Generally, the product is placed in a clean workshop, such as a 100000 level purification workshop, and disposable sterile medical equipment products are placed in bags. Then, the bags are sealed with a heat sealing machine and placed in cardboard boxes for sterilization. The shelf life of the bacteria is generally divided into 1 year, 3 years, and 5 years due to different materials, and all have undergone aging verification to ensure that they are transported, stored, and finally opened by the hospital nurse, The medical products inside the bag are sterile and can be used directly without further sterilization.
Working principle:
By utilizing the semi permeability and antibacterial properties of packaging materials, sterilization gases such as EO epoxy ethane or steam can be transmitted to achieve sterilization effects, preventing bacteria from entering the packaging bag again. Ensure that the packaging bag remains sterile until it is opened during the required storage, transportation, and validity period.
Maintain the sterile state of the product. The packaging should not have the opportunity to be contaminated by air, damaged fibers, dust, or other foreign objects, as well as the invasion of microorganisms. Therefore, packaging needs to ensure that:
1 The packaging materials are undamaged;
2 Completely sealed, with appropriate peeling strength, no penetration, no blasting, and clean peeling.
3 Must adapt to the promised sterilization method ISO11134/ISO11135/ISO11137
