Tyvek is a non-woven polyethylene fabric manufactured by DuPont. It is known for its outstanding strength, durability and tear resistance. As well as industrial use for EO and Gamma sterilization. Tyvek is not suitable for steam sterilization, however perfectly compatible with the requirements of VH2O2 (plasma) sterilization. It is also the first option for gas sterilization, for Tyvek hardly absorbs any toxic gases and thus result in far below legal limit values of residual toxic gas levels.
