Abstract: Methods of forming laminating adhesive articles include providing a multi-layer article, and a tool with a structured surface. The multi-layer articles include a substrate, an adhesive layer, and a liner or may just include an adhesive layer and a liner. The multi-layer article is placed between the structured surface of the tool and a support surface and the tool is embossed against the liner by applying pressure or a combination of pressure and heat. The embossing causes the structures on the surface of the tool to distort the liner and the adhesive layer but does not distort the substrate. The distortion in the liner is retained upon release of the applied pressure. Upon removal of the liner from the adhesive layer, the structures on the adhesive layer are unstable, but do not immediately collapse.

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.
