发明名称 Dry top formed film
摘要 <p>An apertured film is provided for use as a topsheet in an absorbent article. The apertured film includes an apertured continuous layer having a female side that is hydrophilic, and hydrophobic raised lanes extending upward from the female side of the apertured continuous layer. A method of making the film is provided also. The method includes: extruding a flat continuous layer of a polymer melt onto a screen assembly, the upper surface of the continuous layer being hydrophilic; coextruding lanes of a hydrophobic polymer melt onto the upper surface of the continuous layer; and applying a pressure differential across the screen assembly to form apertures in the continuous layer. An absorbent article including the film is provided also.</p>
