Tape Logic® Security Strips on a Roll deliver a tamper-evident closure solution in a distinctive blue finish, constructed at 3.9 mil thickness for reliable adhesion across corrugated cartons, mailers, and envelopes. Each strip measures 2 x 5 3/4 inches and is dispensed from a continuous roll for consistent, repeatable application.

When a strip is disturbed or removed, a permanent "OPENED VOID" message transfers visibly to the substrate, providing an immediate indicator of unauthorized access. Consecutive serial numbers printed at every 5 3/4 inches support chain-of-custody tracking and shipment differentiation — particularly valuable in e-commerce fulfillment, pharmaceutical distribution, electronics shipping, and any operation requiring documented tamper evidence.

The blue color aids quick visual identification against standard kraft and corrugated surfaces. No specialized equipment is needed; strips apply directly to standard packaging to convert it into tamper-resistant closures. Each case contains 24 rolls and ships via parcel carrier.
