Core for Pavement Marking Tape or Other Highly Aggressive Pressure-Sensitive Adhesive Tape

A tape core for highly aggressive pressure-sensitive adhesive tape, comprising:

• a plurality of paperboard plies helically wrapped one upon another about an axis and adhered together to form a tubular tape core, the paperboard plies including an outermost ply and a penultimate ply radially inward of and contiguous with the outermost ply, the outermost ply having a radially outwardly facing surface and an opposite radially inwardly facing surface;
• a coating of a release material disposed on the radially outwardly facing surface of the outermost ply to form a surface from which the pressure-sensitive adhesive tape will readily release;
• and
• one or more visible directional indicators disposed between the outermost ply and the penultimate ply for indicating a correct winding direction in which the pressure-sensitive adhesive tape should be wound onto the tape core;
• the outermost ply having a sufficient transmissivity to visible light that the directional indicator(s) can be seen through the outermost ply.
