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 500-label small operational supply, this Blue micro-strip (0.75" x 0.25" / 19mm x 6mm) format is suited for low-volume ongoing operations and boutique security programs.

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 0.75" x 0.25" (19mm x 6mm) micro-strip is the narrowest rectangular TamperColor® format — engineered for sealing thin packaging edges, SIM card slots, narrow device seams, and blister card perforations where standard-width labels cannot fit.

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.
