VOID Tamper Evident Security Label

The VOID Tamper Evident Security Label is a specialized industrial label engineered to expose unauthorized access attempts. Constructed from a security polyester or BOPP facestock, this label incorporates a tamper-evident acrylic adhesive system that leaves a permanent, hidden VOID message on both the label and the substrate upon removal. Available in three precise thickness options of 25 µm, 38 µm, or 50 µm, the material is supplied with a glassine release liner for reliable die-cutting and dispensing. Designed to work seamlessly with major industrial printers, this label also supports flexographic and gravure printing methods, making it a versatile choice for high-volume security marking operations.

This security label delivers robust performance where verification matters most. Its core feature is the irreversible revelation of a VOID pattern when peeled, providing immediate, visual proof of tampering that deters unauthorized handling. The label supports variable data printing, allowing for barcode and serial number integration to enhance traceability and anti-counterfeiting measures. You can select from transfer types—partial, total, or no transfer—to match your specific security requirements and substrate characteristics. For optimal print durability and scannability, especially for barcodes, a resin ribbon is recommended. While the label is suited for general indoor ranges, the tamper response is confirmed by the selected construction and substrate, so final performance should be validated against your specific application environment.

These labels are ideal for warranty seals, equipment enclosures, packaging security, and asset protection applications where proof of interference is critical. They are available in roll or sheet format to accommodate your existing printing and application workflow. Before placing an order, confirm your required thickness, transfer type, and substrate compatibility with our team to ensure the tamper response meets your expectations. Colorfulttr offers free small roll or sheet samples—you only cover the freight—and supports custom printing of variable data, text, or logos.
