The Blue 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 10,000-label enterprise bulk supply, this Blue 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 bold blue face creates an immediately recognizable security seal that stands out on light-colored and neutral packaging surfaces. Blue TamperColor® labels are widely used for color-coded security systems where blue designates a specific product category, department, or verification tier. 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.

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.
