An article, including a network of interconnected polymeric strands; wherein each of the interconnected polymeric strands has a first surface adapted to contact a tissue site and a second surface opposite the first surface; wherein at least one of the interconnected polymeric stand has a plurality of features extending from the first surface of the interconnected polymeric strands; wherein at least one of the interconnected polymeric strands is non-linear; a plurality of openings between adjacent interconnected polymeric strands; an adhesive layer in contact with the second surface of the interconnected polymeric strands; and a filler in contact with the adhesive layer, the adhesive layer in between the network of interconnected polymeric strands and the filler; wherein the article is a negative pressure wound therapy article.

Negative pressure wound therapy article with features

Netting () comprising an array of polymeric strands () periodically joined together at bond regions () throughout the array, and methods and dies for making the same. Nettings described herein have a variety of uses, including wound care and other medical applications, filtration, absorbent articles, pest control articles, and geotextile applications.

Nettings, dies, and methods of making the same

A polymeric netting includes polymeric strands and first and second polymeric ribbons. The first and second ribbons each independently have a height-to-width aspect ratio of at least three to one and a major surface that is intermittently bonded to a polymeric strand, with first and second edges symmetrically disposed on opposite sides of a center line bisecting the major surface. The netting has first and second opposing major surfaces transverse to the major surfaces of the first and second ribbons. The first major surface of the netting includes the first edges of the first ribbons, and the second major surface includes the second edges of the second ribbons. The first ribbons do not extend to the second major surface, and the second ribbons do not extend to the first major surface. Articles including the netting, an extrusion die, and a method useful for making the netting are also disclosed.

Polymeric netting of strands and first and second ribbons and methods of making the same

Polymeric layer having first and second, generally opposed major surfaces, comprising an array of openings extending between the first and second major surfaces. The polymeric layers are useful, for example, as components in personal care garments such as diapers and feminine hygiene products. They can also be useful for filtering (including liquid filtering) and acoustic applications.

Methods of making films comprising an array of openings

A polymeric netting including polymeric ribbons and polymeric strands. Each of the polymeric ribbons and strands has a length and width, with the length being the longest dimension and the width being the shortest dimension. The polymeric ribbons have a height-to-width aspect ratio of at least five to one, a major surface that is intermittently bonded to only one polymeric strand, and a height greater than the height of the one polymeric strand. An extrusion die and method useful for making the polymeric netting are also disclosed.

Polymeric netting of ribbons and strands and methods of making the same

Polymeric layers () comprising an array of blind openings () extending into the first major surface (), but not through the second major surfaces (). The blind openings each have a series of areas through the openings from the first major surface towards the second major surfaces ranging from minimum to maximum areas, where for at least a majority of the blind openings the minimum area is not at the first major surface. At least a portion of the first major surface comprises a first material and extends up to, but not into the second major surface. At least a portion of the second major surface comprises a second, different material. Methods for making the polymeric layers are also disclosed. Polymeric layers are useful, for example, as components in personal care garments such as diapers and feminine hygiene products. They can also be useful for filtering (including liquid filtering) and acoustic applications.
