Abstract: Embossed polymer sheets and interlayers having at least one tapered zone are provided. The roughness of the embossed portion of the sheets and interlayers may be substantially uniform. Methods and systems for producing such interlayers are also described herein and may utilize at least one pair of rollers oriented substantially parallel to one another. When used in multiple layer panels, such as safety glass laminates, the embossed tapered interlayers described herein exhibit excellent optical performance, as indicated by the low haze and high clarity of the resulting panels.
