A structural polymeric composite includes a stiffening layer. The composite is made in a continuous extrusion process in which the stiffening layer is pulled through a cross-head die as a polymer is extruded over it. The layer includes a film or textile carrier, a filler of carbon fibers, fiberglass, organic fibers or minerals forming a mat. A binder may be dispersed over the mat and a second carrier applied. The mat is subjected to heat and pressure to soften the carriers and binder so they penetrate into the interstices of the filler and binds mechanically with them and the carriers and binder bind chemically with each other to form the stiffening layer. A polymer is then extruded over the stiffening layer, which may be used flat, provided with holes or punches for composite action with the polymer, formed into a profile, or segmented to provide spaced-apart stiffening layers.

A sheet of loop material having utility as the landing zone in the manufacture of, e.g. disposable diapers and having excellent properties and an exceptionally low basis weight. Methods and apparatus for forming the sheet of loop material are also disclosed.

A disposable absorbent having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet, is described herein. The topsheet is a two layer composite or laminate web having a first layer and a second layer. The composite or laminate has a first plurality of apertures and a second plurality of apertures, wherein the first plurality of apertures have sidewalls that extend in a first direction, wherein the second plurality of apertures have sidewalls that extend in second direction that is different than the first direction, and wherein the composite or laminate also includes a plurality of embossments which extend in a third direction opposite the first direction.

A biaxially oriented thermoplastic resin film has at least one surface of which has protrusions each having a height of 1 nm or more and less than 2 nm at a density of 110.sup.7 to 110.sup.9 protrusions per mm.sup.2. The thermoplastic resin film is capable of suppressing generation of coarse protrusions and contaminants, and defects in a processing process while having slipperiness.

A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a low force extension.
