Self-seal sterilisation pouches are single-use, two-layer containers with clear film on one side and medical-grade paper on the other. They have an integrated adhesive strip that allows for safe sealing without the need for a heat sealer. They include internal sterilisation as well as sterilisation by steam, ethylene oxide, formaldehyde, plasma, and chemical vapour. http://www.askmap.net/location/7460012/united-states/the-importance-of-disposable-dental-chair-covers-in-maintaining-hygiene-and-comfort
