    Abstract: A laminate of an at least partially reticulated thermoplastic film joined to an extensible carrier. The reticulated thermoplastic film includes a backing with openings and discrete elements protruding from the first major surface. There are two discrete elements aligned in a first direction abutting opposite ends of any given opening. In a second direction perpendicular to the first direction, there is one discrete element between the given opening and an adjacent opening aligned in the second direction. Each portion of the thermoplastic backing around the given opening is plastically deformed in its lengthwise direction. A method of making a laminate is also disclosed. The method includes stretching a thermoplastic backing having a plurality of discrete elements in the first direction and laminating the backing to an extensible carrier. Subsequently stretching the laminate in a second direction forms a tear in the thermoplastic backing between two adjacent of the discrete elements.

    Abstract: A tape includes a tape backing, an adhesive disposed on the tape backing, and a release surface for the adhesive. The release surface is a release coating disposed on at least a portion of a surface of the tape backing. The tape backing comprises a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region.

    Abstract: The composite elastic material (22) includes an elastic layer (4) and a structured film layer (15) having first and second opposing surfaces, with the second surface bonded to the elastic layer (4). The first surface of the structured film layer (15) has upstanding male fastening elements. The structured film layer (15) is gathered such that the upstanding male fastening elements point in multiple directions. The composite elastic material (22) can also be called a stretch-bonded laminate, which include an elastic layer (4) stretch-bonded to a second surface of a structured film layer (15). A first surface of the structured film layer (15), opposite the second surface, has upstanding male fastening elements. A process for making the composite elastic material (22) is also described. An absorbent article including the composite elastic material (22) is also described.

    Abstract: A fastening tape, mechanical fastener, methods of making them, and personal hygiene articles including them are disclosed. The fastening tape includes a tape backing having a fastening portion, an adhesive disposed on the fastening portion, and a release surface for the adhesive. The release surface is a either a release tape attached along one of its edges to the tape backing or a release coating disposed on at least a portion of a surface of the tape backing. At least one of the tape backing or the release surface comprises a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region. The mechanical fastener includes such a microporous film and mechanical fastening elements on at least one surface. The at least one see-through region extends through the thickness of the microporous film.

    Abstract: The method includes unwinding a thermoplastic film from a roll, stretching the thermoplastic film in the machine direction so that it plastically deforms and decreases in width, slitting the stretched thermoplastic film into the multiple mechanical fastening strips, and winding the multiple mechanical fastening strips into multiple rolls. The thermoplastic film has a first surface and a second surface opposite the first surface, and the first surface of the thermoplastic film bears a plurality of male fastening elements. In the method, the unwinding, stretching, slitting, and winding are completed in-line.

    Abstract: A personal hygiene article includes a chassis with a topsheet, a backsheet, and an absorbent component between the topsheet and the backsheet. At least one portion of the personal hygiene article includes a microporous film having an opaque, microporous region and at least one see-through region of lower porosity within the opaque, microporous region. The microporous film can include a beta-nucleating agent or can have thermally induced phase separation caused by a diluent. A container includes a microporous film enclosing at least one personal hygiene article. The microporous film has an opaque, microporous region and at least one see-through region of lower porosity forming a window within the opaque, microporous region. Methods of making the personal hygiene article and container are also described.
