Abstract: Polymeric layers (50) comprising an array of blind openings (56) extending into the first major surface (52, 10111, 11211), but not through the second major surfaces (54, 10112, 11212). 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.

Abstract: A discontinuous silicone article is disclosed that includes a plurality of strands of radiation cured silicone gel arranged to form a net-like structure with openings between strands. The silicone gel provides adhesion to a surface, such as skin, and the openings provide for moisture transmission away from the surface. The discontinuous silicone article comprises at least one adhesive polymer strand and a plurality of joining strands. The adhesive polymer strands comprise a radiation cured silicone gel and each polymer strand repeatedly contacts an adjacent joining strand at bond regions.

Abstract: Polymeric layers (50) comprising an array of openings (56) extending between the first and second major surfaces (52, 54), wherein the openings (60) each have a series of areas through the openings from the first and second major surfaces ranging from minimum to maximum areas. There is a total area and a total open area for each of the first and second major surfaces, wherein the total open area for each of the first and second major surfaces is not greater than 50 percent of the total area of the respective major surface. For at least a majority of the openings (56), the minimum area is not at either major surface. 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 and medical skin applications where breathability is desired. They can also be useful for filtering (including liquid filtering) and acoustic applications.
