Abstract: Composite polymeric comprising, in order, first, second, and third polymeric layers. The first layer is compositionally different than the second layer. The third layer is compositionally different than the second layer. The second layer comprises an array of void spaces therein, but not through the first and second major surfaces. The void spaces each have a series of areas through the void spaces ranging from minimum to maximum areas. The minimum area is not adjacent to either the first or third layer. Methods for making the composite polymeric layers are also disclosed. Polymeric layers described herein 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: 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: 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.
