For use at a crime scene or in a laboratory setting, our Sawtooth Evidence Tape is a generous 1.25" wide and comes on a 108' roll in a dispenser box. No struggling to separate the tape from the tape backing! The end of the tape "pops up" out of the box and away from the liner each time you use it. This Sawtooth Evidence Tape is the most sensitive, tamper-indicating acetate tape available. If physical removal is attempted, the sawtooth edges will tear, while chemical tampering causes the solvent-sensitive dye to dissolve and smear. The permanent adhesive and instantaneous cure time make our tape excellent for sealing all types of evidence containers. Tape is available in a 108 ft roll with free dispenser box.
