Arrowhead SealGuard™ Solid Back Evidence Tape is made with a polystyrene 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. The red or blue tint and black overprint will dissolve and smear when solvents like alcohol and acetone are applied to show positive proof of tampering. Dual-serrated tape edges add redundancy to the integrity. 3" core backed with 78 lb. stock Kraft liner. 108' per roll and packaged in a convenient dispensing box. Solid Back Tape can be used with the desktop evidence tape dispense. FEATURES: Red/White Stripe with ”Evidence” Imprint 1.375" x 108' Packaged in a dispenser box
