The Rainbow TamperGuard® Tamper Evident Security Label is a ready-to-deploy stock tamper seal requiring no custom print setup, lead time, or minimum order for artwork. Apply directly to your product, packaging, or asset for immediate non-residue tamper-evident protection. Available in a 2,000-label mid-volume supply, this Rainbow mid-size rectangle (1.5" x 0.6" / 38mm x 15mm) format is designed for growing operations and multi-product security programs with improved per-label cost efficiency.

The holographic rainbow finish produces a dynamic color-shifting iridescent effect that varies under different viewing angles — simultaneously serving as a premium visual authentication feature and a tamper-evident seal. The rainbow holographic effect is virtually impossible to replicate with standard printing, making these labels both visually striking and inherently anti-counterfeit. The 1.5" x 0.6" (38mm x 15mm) mid-size rectangle provides significantly more visible surface area than compact formats — creating a prominently authoritative security seal across retail packaging, pharmaceutical cartons, and equipment access panels.

TamperGuard®'s defining advantage over standard tamper-evident labels is its non-residue adhesive system: when the label is removed or tampered with, the void pattern activates visibly on the label itself without leaving adhesive residue or ghost marks on the underlying surface. This makes TamperGuard® ideal for sensitive substrates, reusable equipment, high-gloss packaging, and any application where surface integrity must be maintained after a label is assessed or removed.

The blank face is available for hand-marking post-application or use as a clean tamper indicator. For branded print content including logos, sequential numbers, barcodes, or QR codes, see the Custom Print (CTG) version. For a pre-printed "Warranty Void" message, see the Warranty Void (GTG) version.
