Tyvek Rolls & Pouches are prepared with certified peel able neutral and transparent plastic materila coming from a special layer of polyester and polyethylene. On demand we serve pouches to expose with plasma gas, Steam and EO sterilization for heat sensistive surgical instruments. It is simple & easy to distinguish between sterilzed packages from the non-sterilized ones due to sharp change indicator. Tyvek hardly absorbs any toxic gases and thus result in far below allowable limit values of residual toxic gas levels.
