Abstract
An optical product comprised of an optical film and a protective cover has a cover removal tab attached along one edge. The cover removal tab allows the protective cover to be easily and efficiently removed from the optical film. In addition, there is no imprint of the cover removal tab on the optical film when multiple optical products are stacked or rolled up for storage, the protective cover remains the same size as the optical film, adding the cover removal tab to the optical product only requires a one punch-head converting machine, and there is minimal waste of material and time to add the cover removal tab.
