Sirchie SM10002B Blue Sirchmark Evidence Tape - 108 ft

Sirchmark evidence tape is manufactured on a matte acetate base featuring a top surface that may be written on with pencil or pen. It is coated with a permanent, quick-setting acrylic adhesive that defies removal from most surfaces. To increase its ability to tear, it is perforated with 3/16'' slits at 1/4'' intervals. Dual-serrated tape edges add redundancy to the integrity. The top surface is printed in translucent red or blue ink, then overprinted with an opaque black identifier. The roll is 1 1/2'' wide, 0.001'' thick, on a 3'' core and is backed with 50 lb stock Kraft liner. Attempts to remove Sirchmark evidence tape will cause the tape substrate to break and peel off in irregular strips. The blue tint and black overprint will dissolve and smear when solvents like alcohol and acetone are applied - positive proof of tampering. Sirchmark is regularly used by hospitals, laboratories, banks, and race tracks - wherever a tamperproof seal is needed.
