    摘要： A 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 backing around the given opening is plastically deformed in its lengthwise direction and typically has higher stretch-induced molecular orientation at its edge adjacent the given opening than at its midpoint. The openings are often retractable. A method of making a reticulated thermoplastic film is also disclosed. The method includes stretching a thermoplastic backing with a plurality of discrete elements in the first direction. Subsequently stretching the backing in the second direction forms a tear in the backing between two adjacent discrete elements.

    摘要： The article includes a microporous thermoplastic film having first and second major surfaces and having an opaque, microporous region and a see-through region of lower porosity having a pre-determined shape. The article further includes a first adhesive having a first color disposed on the second major surface of the microporous thermoplastic film, wherein a portion of the first adhesive is visible through the see-through region of lower porosity when viewed from the first major surface of the microporous thermoplastic film. The article may include multiple adhesives with multiple colors. A method of making the article is also described.

    摘要： 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.

    摘要： The article includes a thermoplastic layer having opposing first and second side edges and a first surface bearing male fastening elements. The thermoplastic layer is plastically deformed and has a retardance profile having an average retardance along a line from the first edge to a location 500 micrometers from the first edge and a distance from the first edge where 75% of the average retardance is observed of at least 10 micrometers. In some cases, a distance between the first and second side edges is up to 50 millimeters. In some cases, the article is a fastening tab. The method includes providing a thermoplastic film having opposing first and second side edges, with a distance between the opposing side edges of up to 50 millimeters, and stretching the thermoplastic film to form the thermoplastic layer, which is plastically deformed. The first surface of the thermoplastic film bears male fastening elements.

    摘要： 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.
