Abstract: Polymeric multilayer film having first and second generally opposed major surfaces, an array of openings extending between the first and second major surfaces, and a thickness greater than 125 micrometers, wherein there are at least 30 openings/mm2, and wherein the openings each have a series of areas through the openings from the first and second major surfaces ranging from minimum to maximum areas, and wherein the minimum area is not at at least one of the major surfaces. Embodiments of polymeric multilayer film described herein are useful, for example, for filtration and acoustic absorption.
