Abstract
A method for making an apertured film for use as a topsheet in absorbent products wherein the film is corona treated on one side, and has received a surfactant application that is distributed to both the corona treated and non-corona treated sides of the film. A method for application of surfactant includes applying the surfactant to one side of the film and rolling the film into a roll while the surfactant is still wet in order to apply surfactant to both sides of the film.
