At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean, wherein the mean is different than the median. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape. The first shape is positioned within the second shape.

An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

Described are moisture responsive materials. The materials may have tunable moisture permeability. A material may be a substrate that includes apertures. The apertures are configured to open or close depending on the humidity environment to which the substrate is exposed. The apertures have at least two regions of polymer gel, which may have different amounts of crosslinking. The apertures may be formed from at least two polymer gels having at least two different crosslinker loadings. The materials may be used in articles of manufacture. For example, the materials are used in wearable articles, outdoor articles, medical articles, packaging articles, building articles, filtration/separation articles, and the like.

A prepreg formed from a resin and unidirectionally aligned reinforcement fibers, characterized in that: the prepreg is sheet-shaped; the prepreg has cutouts of a depth for cutting the reinforcement fibers, and includes reinforcement fibers (A) cut by the cutouts to a length of 10 to 50 mm and reinforcement fibers (B) having a length of equal to or more than 50% of the sheet length of the prepreg in the alignment direction of the reinforcement fibers; the surface area of a band section including the reinforcement fibers (B) in a plan view is 1.4% to 35.0% of the entire surface area of the prepreg in a plan view; and at least one end of the reinforcement fibers (B) is positioned at an end portion of the prepreg in the alignment direction of the reinforcement fibers.

Briefly, a variety of embodiments of composite materials including part fabrication using composite materials is described.

A disposable absorbent article having a topsheet, a backsheet, and an absorbent core disposed therebetween is described herein. The topsheet includes a first zone disposed between a second zone and a third zone; a first end area and a second end area; and an array of features which includes one of apertures, tufts, ridges, or grooves disposed in the first zone. A plurality of bond sites are disposed in the second and third zones. The plurality of bond sites are configured in a curvilinear manner in at least the first end area or the second end area and mask a boundary of the first zone.

A display substrate and a display device are provided. The display substrate includes a display area located inside the display substrate and a barrier layer, located between the display area and a substrate edge of the display substrate, wherein the barrier layer includes at least two rows of first hole sections arranged alternately on a direction from the display area to the substrate edge, each row of the first hole sections includes at least two first hole sections arranged alternately on an extending direction of the substrate edge, wherein a projection of the first hole sections of the adjacent rows on the extending direction of the substrate edge overlaps each other. By practice of the disclosure, the extending of the crack could be effectively avoided, so the product yield could be improved.

A roofing shingle has a shingle body with at least a top layer having a buttlap portion with a butt edge and a headlap portion. An exposure zone extends from the butt edge toward the headlap portion and is configured to be exposed to the environment when the roofing shingle is installed on a roof. A shadow formation may be located in the exposure zone of the top layer. The shadow formation and the exposure zone differ from each other in at least one aspect, such as color. The top layer may be substantially rectangular and have no tabs formed along the butt edge. A thickness of the exposure zone and a thickness of the shadow formation may be substantially identical. The shadow formation may be a simulated cut out, slit or slot.

A molded product includes a body including a flat part and a projection protruding from the flat part, a design member including a design surface, and an adhesive member sticking the design member to the body. The adhesive member includes a buffer portion formed by cutting off a part of the adhesive member at a position corresponding at least to the projection. Thus, the adhesive member negates differences in level on the body, allowing the design surface to be smooth.

According to some illustrative embodiments, a protective product is provided that includes: an envelope having a two-layer wall structure, the two-layer wall structure including a) a first outer paper layer, and b) a second inner paper layer, wherein the second inner paper layer includes width-wise positional variations of the side surface of the second inner sheet that cushions items placed within an inner pouch of the envelope, and forms an interior wall of the inner pouch of the envelope and directly contacts the items placed within the inner pouch of the envelope. In some preferred implementations, the width-wise positional variations of the side surface of the second inner paper layer includes pleats, undulations and/or embossments, and, preferably, the pleats, undulations and/or embossments include ridges that extend perpendicular or substantially perpendicular to an outlet of the envelope.
