A sterile bag or pouche is a single-use package used in a sterilizer to allow penetration of the sterilant to the objects placed inside. After sterilization, the contents retain their sterility.
The choice between a sterile bag and a sterile pouch depends on factors such as the size and shape of the items, the desired level of protection, and any specific requirements for breathability or transparency. In healthcare settings, both options are used based on the nature of the medical instruments or devices being packaged and the sterilization method employed.
