Abstract
A visual indicator used to indicate a disposition of an end of a tape comprises a colored layer, and one or more layers of elongate polymer elements, or one or more polarizing layers, or one or more dichroic filter layers. When the tape is stretched as a piece is torn or cut away, an orientation of the polymer elements, or a polarization configuration, or a thickness of the dichroic layers is changed, changing a color, opacity, or reflectance visually evident at the end of the tape. In other embodiments, the visual indicator comprises one or more visible lines that run diagonally across the width of the tape, either in successive sections or along the entire length, so that a discontinuity between the line at the end and at an adjacent point on the remainder of the tape indicates the disposition of the end and an approximate amount of tape remaining.
