    VOID Hologram Label Sticker

    When you tear off the label, the material will show " VOID" mark on the surface. It is kind of tamper evident way.Our silver or white polyester VOID labels, also known as Warranty Labels, feature a tamper-evident surface that leaves a "VOID" pattern on the label and the surface when the label is lifted. This tamper evident seal is great for use on electronic equipment, rentals, or any other items when you need to prevent undetected access. These void labels cannot be switched to another piece of equipment without detection. A resin ribbon is required for printing on the VOID labels.
