Help save time with the Scotch® Security Message Box Sealing Tape that eliminates the need for hand writing or adding separate labels, when a package requires that a seal be intact before accepting. On a clear background and printed in red: CHECK SEAL BEFORE ACCEPTING, this tape alerts receiver of the secured-seal requirement and helps keep package safe throughout the shipping process. It is a 1.8 mil industrial-grade polypropylene film packaging tape, with a synthetic rubber adhesive, that offers roll-to-roll consistency, to help increase productivity. It is specifically designed for flexibility and conformability under stress. The tape was engineered to help resist abrasion, moisture, chemicals, and scuffing, for long-lasting performance. The roll is easy to unwind and dispense with manual dispensers or the 3M™-Matic Case Sealer (sold separately). This is ideal for general industrial packaging applications, recycled liner paper and fiberboard, and boxes weighing up to 70 lb.
