An apertured film, suitable for use as a sanitary napkin cover which passes body fluids, is provided. The film comprises a first layer of a first polymeric material and a second layer of a second polymeric material. Both layers are apertured for the transmission of body fluids therethrough. The first polymeric material exhibits a melting point temperature which is greater than the melting point temperature exhibited by the second polymeric material. The apertured film may be thermally bonded by heating the film to a temperature in excess of the melting point temperature of the second layer material and below the melting point temperature of the first layer material. The unmelted first layer will thereby maintain the integrity of the apertured film when the second layer is in its thermally softened condition.

Coextruded apertured film sanitary napkin cover

This invention provides a sanitary napkin of the type emplacement in the inner crotch portion of an undergarment. The napkin comprises a central absorbent element having flaps extending from each of its longitudinal edges. The flaps extend to a sufficient length to allow the flaps to overlie the outer crotch portion of an undergarment with the flaps being sufficiently drapable so as to allow each to fold about the crotch portion at any of an infinite number of lines lying essentially parallel to the junction line between the absorbent element and each flap. Accordingly, when the sanitary napkin is applied to crotch portions of varying width, the napkin will conform to the dimensions of the crotch and be emplaced without wrinkling.
