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.
