Security Bag Tape

Level 3 Blue Tamper Proof Bag Sealing Tape for Tyvek Bags

Engineered specifically for the unique surface of Tyvek bags, this Level 3 blue security tape offers you robust, multi-layered defense.

Any attempt to peel the tape leaves a permanent “VOID” message, providing clear visual evidence for your security protocols.

You can instantly identify thermal attacks, as the integrated thermochromic ink changes color when exposed to heat.

Furthermore, it counters moisture-based tampering by dissolving on contact with water, making reapplication impossible.
