Features









Security
Features
Effects of cold-tampering
Reacts to all cold tampering attempts, generating the appearance of “VOID” and “NUL” graphics via our proprietary cold-indicating technology
Effects of heat-tampering
Reacts to all heat tampering attempts, generating the appearance of blue strips – both on the center and edges of the tape – via our proprietary heat-indicating technology
Proprietary u-cuts
Produced with undetectable incisions along the tape’s border, promoting tearing and distortion upon any attempt to reopen the bag after it’s sealed
Numbers and barcoding
Features high-resolution, scratch and chemical resistant serial numbers and barcodes (1D or 2D) printed with UV-cured ink jet technology, supporting track-and-trace capabilities and preventing duplicate bag replacements
In-line closure
Includes a proprietary, pressure-sensitive sealing mechanism, enabling a consistent, user-friendly sealing process when closing each security bag
Printed liner receipt system
Leverages the adhesive tape liner as the security bag receipt, rendering it impossible to seal the bag shut without first removing and using the receipt
Soluble ink
Utilizes soluble, security graphics below the tape closure that distort and dissolve if exposed to saliva, glycerin, or other liquids/gels
Indented side seals & security printing
Produced with security pouch seals and graphics – indented from the bag’s side – rendering it impossible to slit and reseal the sides without clear signs of tampering
Natural-fold bottom & top construction
Produced with a uniform, folded edge – rather than sealed – rendering it impossible to cut and reseal the bottom and top edges without clear signs of puncturing or slitting
