Advantages of two different medical packaging bags

The main role of sterile packaging materials is to allow air and sterilization media through, but also can provide biological barriers for sterile goods, and then ensure that the sterilized goods in the process of transfer and storage to maintain a certain period of asepsis, today briefly introduce the following two different packaging bags.

1. The medical paper plastic packing bag is made of a layer of special paper and a layer of PET-PP plastic composite film through thermal bonding treatment. It is both permeable and transparent. The medical paper plastic packaging bag needs to go through special heat sealing machine to seal the two ends when it is used. Its disadvantage is that one side is permeable, and some items are easy to produce condensed water during sterilization, so it can not be used before verification. The effective aseptic shelf life of sterile articles packaged in general medical paper plastic packaging bag is 6 months.

2. The main material for medical non-woven packaging material polypropylene, the fiber gap is small and the structure of the random characteristics, and thus can significantly reduce the possibility of microorganisms or dust particles were transferred, aseptic package can be stored longer, disposable supplies, won't produce cotton dust causing air pollution, good air permeability and the balance of bacteria resistance, Medical non-woven fabrics are suitable for pressure steam sterilization and EO sterilization, but non-woven fabrics containing plant fibers are not suitable for low temperature plasma sterilization.
