What is a tamper evident label?Tamper evident labels are security stickers designed to make unauthorized access immediately and permanently visible. When someone attempts to peel, lift, or transfer the label, the material reacts — leaving a hidden "VOID" message, a checkerboard pattern, or breaking into fragments that cannot be reapplied. The label can no longer be removed and replaced without leaving evidence behind. Businesses use tamper evident labels for product authentication, warranty seals, retail loss prevention, packaging security, calibration verification, asset tracking, controlled-access seals, food safety packaging, and brand protection. The right label depends on the surface, the environment, and what you want to happen when someone tries to remove it.

A tamper evident label is an adhesive seal that leaves a permanent, visible mark — typically a VOID message, broken pattern, or fragmented material — when removed, proving that a product, package, or access point has been opened. How does a void sticker work? A void sticker uses a multi-layer adhesive that bonds aggressively to a surface. When peeled, the top layer separates and leaves behind a hidden VOID message or pattern on both the surface and the removed label, making tampering immediately visible and preventing reapplication. What is the difference between destructible and non-residue tamper evident labels? Destructible labels break apart into small fragments when removal is attempted, preventing transfer or reuse. Non-residue labels show clear tamper evidence on the label itself but lift cleanly without leaving adhesive behind on the surface. Choose destructible for asset protection and non-residue when surface cleanliness matters after removal. Will tamper evident labels leave residue on my product? It depends on the material. Standard metallic void labels leave a VOID pattern in residue on the surface. Non-residue tamper evident labels are specifically engineered to remove cleanly while still showing tampering. Intertronix offers both options so you can match the label to your product and removal requirements. Can tamper evident labels be used outdoors? Yes. Industrial-grade tamper evident labels are engineered for outdoor use and resist UV exposure, temperature swings, moisture, and rough surface textures. Standard indoor labels are not rated for prolonged sun or weather exposure. Request a material selector guide or samples to match the right label to your environment. Can I print custom serial numbers, barcodes, or logos on tamper evident labels? Yes. Intertronix prints sequential serial numbers, 1D and 2D barcodes (Code 128, QR, Data Matrix), company logos, custom warning text, and brand-specific color schemes on tamper evident labels. Customization is available on metallic, hologram, destructible, and non-residue materials. What is the minimum order quantity for custom tamper evident labels? Minimum order quantities vary by label type and customization. Many stock and custom-print options start at 250 to 1,000 labels per order. Contact Intertronix for exact minimums based on the material, size, and print specifications you need. Does Intertronix ship tamper evident labels internationally? Yes.
