Abstract: A film having first segments and second segments arranged across the film's width direction is disclosed. The first and second segments are separated from each other by polymer interfaces. The first segments include a first polymeric composition and the second segments include a second polymeric composition. At least some of the second segments are layered second segments having first and second layers in the film's thickness direction, and one of the first or second layers includes a third polymeric composition different from the second polymeric composition. An extrusion die useful for making the film and a method for making the film using the extrusion die are also disclosed.

Abstract: A method of making a mechanical fastening net. The method includes providing a net having strands of polymer and open areas between the strands of polymer and molding a portion of the polymer in the strands of the net into upstanding posts to form the mechanical fastening net. A mechanical fastening net that includes a polymeric backing, a plurality of openings in the polymeric backing, and upstanding posts on at least one of the first or second major surface of the polymeric backing is also disclosed. The polymeric backing has a range of thicknesses ranging from minimum to maximum thickness, and for at least a portion of the polymeric backing, the minimum thickness of the polymeric backing is where it abuts one of the openings.

Abstract: 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.

Abstract: Three-dimensional polymeric strand netting, wherein a plurality of the polymeric strands are periodically joined together in a regular pattern at bond regions throughout the array, wherein a majority of the polymeric strands are periodically bonded to at least two (three, four, five, six, or more) adjacent polymeric strands, and wherein no polymeric strands are continuously bonded to a polymeric strand. Three-dimensional polymeric strand netting described herein have a variety of uses, including wound care, tapes, filtration, absorbent articles, pest control articles, geotextile applications, water/vapor management in clothing, reinforcement for nonwoven articles, self bulking articles, floor coverings, grip supports, athletic articles, and pattern coated adhesives.
