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 1,000-label standard mid-volume supply, this Blue slim strip (1" x 0.375" / 25mm x 9mm) format is suited for consistent monthly production operations and standard 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 1" x 0.375" (25mm x 9mm) slim strip spans wider seams and interfaces than micro-strips while maintaining a low profile — ideal for clamshell packaging edges, thin device panel seams, and compact product closures.

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.
