Autoclave pouches self sealing, also called sterilization pouches for autoclave, protect dental instruments during the sterilization process in an autoclave. The process ensures that the dental instruments remain sterile until opened, and ready for patient use by preventing recontamination after sterilization. Essentially, they maintain the sterility of the instruments by allowing the sterilizing agent to penetrate while also creating a barrier against outside contaminants once sterilized.
