  • Aggressive adhesive and sensitive film makes this label nearly impossible to defeat
  • Small label footprint possible

Security Labels

Made from a specially layered film consisting of aluminum, polyester, and a patented optical film, these tamper-evident labels are nearly impossible to defeat. Superior to adhesive-based materials, these labels react to pressure that happens during attempted removal, which means they are more sensitive and less susceptible to attempts to defeat the security feature. Upon tampering, a hidden message will be permanently shown.


Available in a variety of metallic colors and customized messages that are revealed upon tampering.


Additional Info: Surface should be cleaned with a residue-free solvent like isopropyl alcohol and thoroughly dried before applying label. Adhesive residue from tamper evident feature may be cleaned with a citrus based cleaner like the brand named “Goo-Gone.”


We recommend the customer thoroughly evaluate these products prior to use in order to determine acceptability to their specific applications.  Our testing shows the tamper-evident feature becomes permanently non-functional after exposure to temperatures above 104ºF.
