Abstract
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.
