The Rainbow TamperColor® Custom Print Tamper Evident Security Label Seal Sticker combines the TamperColor® tamper-void security mechanism with your choice of custom-printed content — logos, sequential numbers, barcodes, QR codes, department codes, or any design that transforms the tamper seal into a branded product authentication and identification tool. Available in a 5,000-label high-volume supply, this Rainbow slim strip (1" x 0.375" / 25mm x 9mm) format is suited for high-frequency production lines and large-scale sealing operations.

The dazzling rainbow holographic finish produces a dynamic, iridescent color-shift effect that changes appearance at different viewing angles — serving simultaneously as a premium visual authentication feature and a tamper-evident seal. Rainbow TamperColor® labels are virtually impossible to replicate with standard printing, making them a natural choice for high-value goods and branded authentication programs. The 1" x 0.375" (25mm x 9mm) slim strip spans wider seams and interfaces than micro-strips while maintaining a low profile — ideal for clamshell packaging edges, thin device panel seams, and compact product closures.

When any removal attempt is made, the TamperColor® label responds with an irreversible color-change void pattern — the proprietary adhesive system leaves a permanent, chromatic tamper-evident mark on both the label face and the substrate surface that cannot be cleaned off, reapplied, or disguised. Unlike standard tamper-evident labels that simply fragment or leave residue, TamperColor® creates a vivid color-pattern void that is immediately and unmistakably visible — even to untrained eyes at a glance.

Custom print options include serialized sequential numbers for item-level traceability, integrated barcodes compatible with major asset management platforms, QR codes for mobile scanning authentication workflows, and full-color logos for branded product security programs.
