The Rainbow TamperColor® Tamper Evident Security Label Seal Sticker is a ready-to-deploy stock tamper seal requiring no custom print setup or lead time. Apply directly to your product, packaging, or asset for immediate tamper-evident protection. Available in a 250-label starter/evaluation pack, this Rainbow extra-wide rectangle (2.75" x 1" / 70mm x 25mm) format is suited for testing, pilot programs, or targeted specialty applications.

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 2.75" x 1" (70mm x 25mm) extra-wide rectangle is the widest TamperColor® format — spanning large packaging box closures, wide equipment panels, and substantial product surfaces with a single seal that commands immediate visual attention.

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.

The blank face can be hand-marked post-application or used as a clean, unprinted tamper indicator. For organizations needing printed content such as barcodes, serial numbers, or logos, see the Custom Print (CTC) or pre-printed Warranty Void (GTC) versions.
