Tamper Evident Labels & Security Seals — Made in the USA

Tamper evident labels are adhesive seals engineered to leave permanent, visible proof that a product, package, or asset has been opened or interfered with. Unlike standard labels, tamper evident labels respond to removal attempts by revealing a hidden VOID message, fragmenting into pieces, or leaving an irremovable residue pattern — making tampering immediately obvious and impossible to conceal. Once disturbed, the evidence cannot be reversed.

Intertronix manufactures tamper evident labels, void stickers, and custom security seals from its Chula Vista, California facility and ships worldwide. Our product line covers every major tamper evident material including metallic void, holographic, destructible vinyl, non-residue, color-changing, industrial high-resistance, and holographic strip constructions — each engineered for a specific combination of surface, environment, removal behavior, and security level. All labels are available blank for immediate shipment or custom printed with logos, sequential serial numbers, barcodes, and warning text.

Choosing the right tamper evident label depends on four factors: the surface you are applying to, the environment the label must survive, what evidence should remain after removal, and whether visual authentication is also required. A metallic void label that works perfectly on a smooth plastic panel will fail on a textured powder-coated surface. A standard indoor label will degrade outdoors within weeks. Getting the material match right before ordering saves time, money, and the liability of labels that fail in the field.

Shop by Label Type

Metallic void labels are the most widely used tamper evident solution, featuring bright or matte silver polyester with a hidden VOID message that appears on both the surface and the removed label when peeled. Holographic security labels combine visual authentication with tamper evidence, using iridescent laser-demetalized designs that are extremely difficult to replicate. Non-residue labels provide clear tamper evidence on the label itself while lifting cleanly from the surface without adhesive contamination — ideal for returnable packaging and customer-facing product seals. Destructible labels are made from brittle vinyl that physically shatters into small fragments on removal, making transfer or reuse physically impossible. Industrial high-resistance labels withstand UV exposure, moisture, wide temperature ranges, and rough surfaces for outdoor and harsh-environment applications. Color-changing TamperColor® labels reveal a VOID pattern and color shift simultaneously, combining brand customization with tamper evidence. Security tape seals cartons, shipping containers, and access panels with a VOID message that appears permanently on the surface when cut or peeled.
