Abstract
A wetness indicating polymeric film and method of making the film is provided. The method includes feeding a polymer film into a flexographic printing apparatus; printing at least one wetness indicator ink onto a first side of the perforated polymer; and perforating the polymer film by forming a plurality of apertures or enlarged micropores that extend from the first side to the second side. The apertures or enlarged micropores permit a sufficient quantity of an aqueous liquid to pass from the second side through the perforated polymer film to the first side. Upon contact, the aqueous liquid reacts with the wetness indicator ink to cause a color change visible by an unaided human eye. In an absorbent article including the inventive film as a backsheet, the total amount of liquid that passes through the backsheet is negligible and the barrier properties of the backsheet as a whole are not compromised.
