    摘要： The invention is a display article having a flexible substrate which includes a writing surface capable of being used as a dry erase surface. A peripheral edge extends around the writing surface. A flexible framing strip is affixed to the writing surface at a position proximate to the peripheral edge. One embodiment of the display article can be made by forming a substrate having a writing surface. The substrate defines a periphery edge, a back surface, and a plurality of mushroom shaped hooks extending from the back surface substantially over the entire back surface. The writing surface is capable of being used as a dry erase surface. At least a portion of the periphery of the writing substrate is folded over to form a framing strip having a plurality of exposed mushroom shaped hooks. The framing strip is secured to the writing surface.

    摘要： Polymeric multilayer film having first and second generally opposed major surfaces, and comprising first, second, and third layers, an array of blind openings between the first and second major surfaces, and an average thickness, wherein the first, second, and third layers each have a first average thickness excluding any thickness said first, second, and third layers having in any of the blind openings, wherein the first and second layers extend into the first average thickness of the third layer, wherein each of the first, second, and third layers each have a second average thickness (including a thickness of zero) in the blind holes, wherein the second average thickness of the first and third layers are each greater than zero, and wherein the ratio of the first average thickness of the second layer to the second average thickness of the second layer is at least 2.1; and method of making the same. Embodiments of polymeric multilayer film described herein are useful, for example, for acoustic absorption.
