A backing sheet for use in a wound dressing includes a semipermeable continuous film laminated to an adhesive-coated apertured layer. The apertured layer is a solid substrate coated with a medically acceptable adhesive. A method of making a backing sheet for use in a wound dressing includes the steps of: forming an adhesive-coated apertured layer by coating a medically acceptable adhesive onto an apertured solid substrate, followed by laminating the adhesive-coated apertured layer to a semipermeable continuous film.

An improved expandable slit-sheet stock material is configured to aid in temporarily restricting opening of a plurality of slits of the slit-sheet stock material, such as during winding of the unexpanded stock material or during expansion of the stock material. Each slit of the plurality of slits includes one or more un-slit reinforcement portions, such as reinforcement ties, extending fully between opposite longitudinal sides of the slit, and disposed between opposed transverse endpoints of the slit. The reinforcement ties minimize or prevent tearing of the stock material during the winding or expansion. A dunnage conversion system for expanding the slit-sheet stock material includes an expander having a pair of opposed rollers. The rollers engage the stock material to effect breaking of the un-slit reinforcement portions and expansion of the slit-sheet stock material.

A composite panel having a plurality of carbon plies, a perforated metallic foil comprising several apertures and being secured to the plurality of carbon plies, and a protective layer made from resin secured to the metallic foil. The perforated metallic foil is embedded in the protective layer through its apertures. A free surface of the protective layer forms a top side of the composite panel. The thickness of the protective layer between the top side of the composite panel and the perforated metallic foil is at least 15 micrometers and the perforated metallic foil has a thickness of not more than 30 micrometers. The plurality of apertures in the aggregate defines an open area of not more than 40% of the surface area and a maximum distance between two opposed points in a perimeter of an aperture is equal to or less than 3 mm

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

Electronic equipment may include structured fabric. Structured fabric may be used as a protective case or cosmetic cover for an electronic device, may be used to form a band that holds an electronic device against a user's body, or may be used to cover one or more openings in an electronic device. Structured fabrics may be soft and pliable while maintaining the ability to hold a given shape without added support. Structured fabric may be formed by laminating fabric such as warp-knit fabric with a stiffener such as polymer film. Structured fabrics may include openings through which signals such as optical or audio signals pass. To maintain the geometry and shape of the openings in the structured fabric without covering the openings, the stiffener and adhesive that are attached to the fabric may be cut to form a pattern of openings that align with the openings in the fabric.

A method of manufacturing a part having an opening for receiving an insert, including forming the opening having an internal surface wherein the internal surface has a polygonal cross-section including a plurality of sides. The polygonal cross-section comprises a polygon having an area larger than a cross-section of the insert, and the sides constrain the insert so as to locate the insert in the opening when the insert is inserted into the opening.

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.
