Tamper Evident Labels, Void Stickers & Security Seals — Made to Order in the USA

Metallic Void Labels

The most widely used tamper evident solution. Bright silver polyester construction with a hidden "VOID" message that appears on both the surface and the removed label when peeled. Available in standard silver, custom printed, serialized, and barcode versions. Suitable for electronics, equipment seals, packaging closures, and warranty stickers on smooth surfaces. Aggressive adhesive bonds to most plastics, metals, and coated cardboard.

Hologram Security Labels

Premium visual authentication combined with tamper evidence. Custom embossed holograms and laser-demetalized designs create a distinctive, iridescent appearance that is extremely difficult to replicate with standard printing equipment. Used for brand protection, certificate authentication, premium product packaging, and high-value asset sealing. Custom holographic designs can incorporate logos, serial numbers, and QR codes.

Non-Residue Labels

Designed for situations where tampering must be detectable but surface cleanliness after removal is required. Non-residue tamper evident labels leave a clear tamper mark on the label itself — such as a void pattern or color change — while lifting from the surface without adhesive residue. Ideal for returnable packaging, rental equipment, clean-room environments, customer-facing product seals, and surfaces where adhesive contamination is unacceptable.

Destructible Labels

Made from ultra-thin, brittle vinyl that physically breaks apart into small, irremovable fragments when any removal is attempted. Because the label cannot be lifted in one piece, it cannot be transferred to a counterfeit product or reapplied to a different item. Commonly used for high-value electronics, jewelry, pharmaceutical packaging, license stickers, and any application where label reuse must be made physically impossible.

Industrial Tamper Evident

Engineered for demanding environments where standard labels would fail. Industrial tamper evident labels withstand UV exposure, moisture, wide temperature ranges (from sub-zero to high heat), rough or irregular surfaces, and chemical exposure. Used for outdoor equipment, HVAC and utility panels, vehicles, heavy machinery, calibration seals on gas pumps and meters, and any application requiring long-term durability alongside tamper evidence.

Jewelry Security Tags

Tamper evident tags purpose-built for rings, bracelets, watches, eyewear, handbags, and other high-value retail accessories. Loop-style and adhesive-backed options available, with custom printing for brand name, price, SKU, and barcode. Designed to attach securely without damaging delicate finishes while still providing clear loss prevention and inventory control at point of sale.

Security Tape

Tamper evident tape for sealing boxes, cartons, shipping containers, and sealed access panels. When cut or peeled, the tape leaves a permanent "VOID OPENED" message on the surface beneath, providing immediate visible evidence of tampering during shipping and handling. Available in standard and custom widths, printed with company name, warning messages, or sequential numbering for chain-of-custody tracking.

Asset Identification Labels

Durable asset tags that combine tamper evidence with long-term equipment tracking. Laser-demetalized customization enables permanent serial numbers, barcodes (Code 128, QR, Data Matrix), and asset identification data that cannot be altered without visible destruction of the label. Used by IT departments, facilities management, government agencies, and any organization that needs a permanent, tamper-evident record attached directly to physical assets.

Compliance-ready tamper evident seals for legal cannabis packaging, exit bags, child-resistant containers, and dispensary products. Many jurisdictions require visible tamper evidence on cannabis packaging by law. Intertronix supplies serialized seals that meet state-level labeling and traceability requirements.

Warranty void labels for laptops, smartphones, tablets, gaming consoles, power supplies, circuit boards, and access panels. Placed over screws, seams, or battery compartments, these seals immediately indicate unauthorized disassembly — voiding the warranty and deterring third-party repair fraud.

Minibar inventory seals, room-service container seals, spa product seals, and restricted-access labels for hotels, resorts, and cruise ships. Custom-printed labels with property name and branding deter theft and product tampering while reinforcing guest trust in product integrity.

Tamper evident seals for food delivery bags, takeout containers, meal kits, retail food packaging, and catering. Consumer demand for visible tamper evidence on delivered food has grown significantly, and many delivery platforms now require it. Intertronix supplies paper, polyester, and specialty adhesive options for both hot and cold food packaging surfaces.

Calibration seals for fuel pumps, scales, utility meters, and inspection equipment. Regulatory agencies require tamper evident seals on calibrated equipment to verify that settings have not been altered between inspections. Industrial-grade materials are required to withstand outdoor exposure and petroleum-based environments.

Chain-of-custody seals, controlled-access labels, evidence seals, asset identification, and tamper evident packaging for government agencies, law enforcement, defense contractors, and regulated industries. Serialized labels with sequential numbering and barcode tracking provide verifiable chain-of-custody documentation.

Hologram authentication labels, custom serialization, laser-demetalized security features, and covert anti-counterfeit packaging for consumer goods, luxury products, and regulated items. Counterfeit products cost brands billions annually — a properly implemented tamper evident and authentication program makes duplication commercially non-viable for counterfeiters.

Container seals, carton-sealing tape, shipment integrity labels, and pallet security seals for freight, e-commerce fulfillment, and third-party logistics. Tamper evident seals on shipping containers create visible accountability throughout the supply chain, reducing shrinkage and facilitating damage claims with clear evidence of when and where access occurred.

What is a tamper evident label?

A tamper evident label is an adhesive seal engineered to leave a permanent, visible mark — typically a VOID message, broken pattern, or fragmented material — when removed or disturbed. Once the label has been tampered with, the evidence cannot be reversed or concealed, proving that a product, package, or access point has been opened. They are used for product authentication, warranty enforcement, packaging security, retail loss prevention, and regulatory compliance across industries.

How does a void sticker work?

A void sticker uses a multi-layer adhesive construction that bonds aggressively to a surface. When peeled, the top face layer separates from the adhesive layer and leaves behind a hidden VOID message or pattern — permanently imprinted on both the surface beneath and the removed label itself. This makes tampering immediately visible from both sides and prevents the label from being cleanly removed and reapplied to a different product.

What is the difference between tamper evident and tamper proof labels?

Tamper evident labels show visible evidence that tampering has occurred — they do not physically prevent removal. Tamper proof labels are designed to resist or prevent removal entirely, typically through extremely aggressive adhesive, mechanical fastening, or destructible construction. In practice, most security applications use tamper evident labels because the goal is detection and accountability rather than physical prevention, which is rarely achievable with a label alone.

What is the difference between destructible and non-residue tamper evident labels?

Destructible labels are made from brittle vinyl that physically shatters into small fragments when any removal is attempted, making transfer or reuse impossible. Non-residue labels show clear tamper evidence on the label itself — such as a VOID pattern or color change — but lift from the surface without leaving adhesive behind. Choose destructible for high-security asset protection where label reuse must be prevented, and non-residue when surface cleanliness or product presentation matters after the seal has been removed.

Will tamper evident labels leave residue on my product?

It depends on the label type. Standard metallic void labels are designed to leave a VOID pattern in adhesive residue on the surface — that residue is the evidence. Non-residue tamper evident labels are specifically engineered to show tampering on the label itself while removing cleanly from the surface without adhesive contamination. Intertronix offers both options so you can match the label to your product surface, removal requirements, and downstream use.

Can tamper evident labels be used outdoors?

Yes, with the right material. Industrial-grade tamper evident labels from Intertronix are specifically engineered for outdoor use and rated to withstand UV exposure, moisture, temperature extremes from sub-zero to high heat, and rough surface textures. Standard indoor-rated metallic void and holographic labels are not designed for prolonged outdoor exposure and will degrade. Always request a material selector guide or test samples before deploying labels in outdoor or harsh environments.

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 across metallic, holographic, destructible, and non-residue label materials. Custom serialization can be specified to integrate directly with your inventory, ERP, or compliance tracking systems. Contact Intertronix for a custom print quote.

What is the minimum order quantity for custom tamper evident labels?

Minimum order quantities vary by label type, material, and customization complexity. Many stock and custom-print options start between 250 and 1,000 labels per order. High-volume production runs are available with pricing that scales down at quantity thresholds. Contact Intertronix directly with your material, size, print specifications, and required quantity for an accurate minimum and lead time.

Does Intertronix ship tamper evident labels internationally?

Yes. Intertronix ships tamper evident labels and security seals worldwide from its manufacturing and fulfillment facility in Chula Vista, California, USA.
