The Rainbow TamperColor® Rainbow Demetalized Laser Cut Tamper Evident Security Label delivers an extraordinary combination of security technologies: the iridescent rainbow holographic finish of TamperColor® rainbow combined with precision laser demetalization — a process that selectively removes metallic material to create permanent, unforgeable patterns or text that are visible only at certain angles and impossible to replicate without the original production equipment. Available in a 10,000-label enterprise bulk supply, this Rainbow large rectangle (2" x 0.75" / 51mm x 19mm) format is suited for enterprise-scale operations, national manufacturers, and maximum per-label cost efficiency.

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 2" x 0.75" (51mm x 19mm) large rectangle combines generous width with meaningful height — providing a substantial security seal footprint on product boxes, equipment access panels, and pharmaceutical carton closures where both physical coverage and visual authority are required.

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.

Laser demetalization creates authenticated patterns — geometric designs, text, or logos — by selectively removing the reflective metallic layer of the holographic film. This process produces authentication features that are optically variable (visible from some angles, invisible from others), making them one of the most sophisticated anti-counterfeiting mechanisms available on a pressure-sensitive security label.
