In an apparatus for treating, for purposes of sterilization, a continuous material web a first treatment station is provided and includes a device for bringing a material web into contact with liquefied hydrogen peroxide. A second treatment station is also provided in which the material web is simultaneously sterilized with hydrogen peroxide vapor and dried with heated air after treatment of the material web in the first treatment station. The second treatment station includes an elongate chamber having an inlet and outlet, the material web being dried and thereby generating hydrogen peroxide vapor as it is led through the elongate chamber from the inlet to the outlet. The second treatment station also includes an outer flow duct in flow communication with the inlet and outlet of the elongate chamber. Heated, hydrogen peroxide-free air is supplied into the outer flow duct such that a portion of the hydrogen peroxide vapor generated by drying the material web and the heated air flows from the elongate chamber into the outer flow duct and mixes with supplied air to form a mixture, and such that the mixture flows through the elongate chamber in the direction of movement of the material web.
