Tamper Evident Barcode Labels


  • Clear visual indication the product has been opened or tampered with
  • Custom printing to display any type of messaging
  • Boosts customer confidence in product integrity
  • Discourages product modification and theft

Discourage theft and keep your property intact with Metalcraft’s Tamper-Evident Barcode Labels.

If someone attempts to remove the label, the word “VOID” is left behind on the surface of the asset and the back of the label. Add a barcode and/or human readable number to the label and use it as part of an overall asset tracking system.

Use these labels to make a statement about your company or school by displaying a logo or stylized type in any of our standard colors – or select a custom color at no additional charge. Subsurface printing provides an extra layer of protection for logos, copy and barcode against solvents, caustics/acids and mild abrasion. This unique process eliminates the need for a laminate thereby eliminating the additional cost as well as the possibility of delamination.

Potential Applications for Tamper Evident Barcode Labels

Asset Tracking – the barcode and human readable ID number on Tamper-Evident Barcode Labels can be used to track information about the asset the label is adhered to, i.e., laptops, furniture, containers, pallets, equipment and more.
