What Is a VOID Label?
A VOID label is a tamper evident security label reveals a hidden message such as “VOID,” “OPENED,” or a custom warning when removed. Depending on the label type, the message may appear on the surface, on the label itself, or both.
These labels help protect product integrity by making unauthorized opening, replacement, or resealing immediately visible.
VOID labels are widely used for electronics, pharmaceuticals, logistics, government documents, retail packaging, and high-value products. They can be customized with PET, destructible vinyl, aluminum foil, serial numbers, barcodes, QR codes, holograms, and custom die-cut shapes.
Current Situation
VOID labels are widely used in electronics, pharmaceuticals, logistics, government documents, and retail packaging. Common materials include PET, destructible vinyl, and aluminum foil.
For B2B projects, labels can be customized with die cuts, barcodes, serial numbers, QR codes, holograms, and different adhesive levels to match product surfaces and security requirements.
Future Development Outlook
In the future, VOID labels may integrate with QR codes, IoT tracking, or blockchain-based traceability systems for higher-value products and regulated supply chains.
For most B2B buyers, the key focus is still practical: clear tamper evidence, stable adhesion, custom branding, and reliable batch production.
Applications
VOID labels are used to prevent unauthorized opening, product replacement, and tampering during storage, shipping, and retail handling.
Typical applications include electronics packaging, pharmaceutical boxes, logistics cartons, government documents, warranty seals, luxury goods, and retail anti-counterfeit packaging.
Production Process
VOID label production usually includes material selection, hidden-message coating, adhesive coating, printing, die cutting, numbering or barcode processing, and quality testing.
For custom orders, buyers should confirm the surface material, label size, VOID effect, adhesive strength, printing content, quantity, and packaging requirements before production.
Why VOID Labels Matter
VOID labels matter because they make product tampering visible, traceable, and difficult to hide. For B2B buyers, this is especially important when products move through multiple warehouses, distributors, customs points, or retail channels.

Types of VOID Labels
VOID labels are mainly divided by how the tamper-evident message appears after removal. For B2B buyers, the right choice depends on the application surface, security level, and whether residue is acceptable.
| Type | How It Works | Best For |
|---|---|---|
| Full-Transfer VOID Labels | Leaves a clear VOID message on the applied surface after removal | Paper cartons, shipping boxes, outer packaging |
| Partial-Transfer VOID Labels | Part of the VOID message remains on the label and part transfers to the surface | Electronics, medical devices, warranty seals |
| Non-Transfer VOID Labels | VOID message appears on the label only, leaving the surface clean | Metal, glass, leather, reusable assets, luxury goods |
B2B Selection Tips
Choose full-transfer VOID labels when you need strong visible evidence on disposable packaging.
Choose partial-transfer VOID labels when you need dual evidence for warranty, after-sales, or dispute handling.
Choose non-transfer VOID labels when the surface must remain clean, reusable, or high-value.

How VOID Tamper Evident Labels Are Made
VOID tamper evident labels are produced through a controlled process that combines substrate selection, adhesive coating, hidden VOID message creation, surface finishing, and die-cutting. Each step affects how the label bonds, how clearly the tamper evidence appears, and whether it matches the final application surface.
| Step | Purpose | B2B Consideration |
|---|---|---|
| Substrate Selection | Choose PET, destructible vinyl, or special films | Match the surface, durability, and security level |
| Adhesive Coating | Control bonding strength and VOID transfer | Adjust for cartons, glass, metal, plastic, or cold-chain use |
| VOID Message Activation | Create hidden VOID / OPENED / custom warning text | Decide full-transfer, partial-transfer, or non-transfer effect |
| Printing & Finishing | Add logo, QR code, barcode, serial number, or coating | Support branding, traceability, and compliance |
| Die-Cutting & Rewinding | Convert labels into rolls, sheets, or custom shapes | Fit manual use or automated labeling machines |

Key Features of VOID Labels
High-quality VOID labels are not just single-purpose anti-counterfeiting tools — they integrate tamper-evident design, multifunctional materials, and customized technology to provide industries with visible tampering evidence and supply chain trust assurance.
The following sections, supported by real-world case studies, explain each feature’s technical details and practical value so that B2B buyers can clearly understand their critical role in industrial applications.
Tamper-Evident Design
Technical Details:
Built on a dual-layer mechanism of substrate fracture + irreversible adhesive transfer. When removed, the label either breaks apart (non-transfer type) or reveals VOID text (“VOID,” “OPENED,” “TAMPERED”) through complete or partial transfer.
The traces result from physical destruction, which cannot be repaired, glued, or covered — easily identifiable by the naked eye without special tools.
Scenario & Case Study:
- Medical Device Sealing:
In 2023, Johnson & Johnson Medical (U.S.) applied VOID labels to insulin pumps exported to Europe.
The label used a “fractured substrate + VOID reveal” design — if a hospital disassembled the device during warranty, the label would instantly break and display “VOID.” This reduced invalid warranty claims by 80% and fully complied with EU MDR medical device regulations.
Application Value:
Provides visible evidence of tampering, prevents counterfeit relabeling, clarifies warranty responsibility, and reduces compliance risk — essential for medical, financial, and aerospace sectors demanding product integrity.
Material Versatility
Technical Details:
Available in four major material types — PET, vinyl, fragile paper, and eco-friendly biodegradable substrates — each optimized with specific adhesive formulations for different surfaces.
- PET: Temperature resistant (–40°C to 80°C), abrasion-proof, ideal for outdoor/extreme use.
- Vinyl: Flexible, suitable for curved surfaces.
- Fragile paper: High tamper sensitivity (tensile strength ≤5 N/25 mm).
- Eco-friendly materials: FDA/REACH compliant for food and pharma applications.
Scenario & Case Study:
- Plastic / Curved Surfaces:
In 2023, Sony Japan applied vinyl-based VOID labels on curved Bluetooth earphone shells.
The flexibility ensured full surface adhesion without peeling, while the label fractured on removal to reveal “VOID,” cutting counterfeit product rates by 70%.
Application Value:
Overcomes the “one label for one surface” limitation — whether applied on smooth glass, curved plastics, or food/pharma packaging, suitable substrates ensure firm adhesion and consistent tamper performance.
Customization Options
Technical Details:
Supports full-spectrum customization:
- Visual: Brand logo, warning text (e.g., “Warranty Void,” “Duty-Free Item”), microtext, or fluorescent security graphics.
- Functional: QR codes for traceability, 16-digit encrypted serial numbers linked to ERP systems, or barcodes for warehouse scanning.
Custom elements are integrated without weakening the VOID effect.
Scenario & Case Studies:
- Brand Identity + Traceability:
In 2023, Gucci Italy used custom VOID labels with double-G logo and unique QR codes on handbags.
Scanning the code revealed factory, logistics, and store data; if removed, both “VOID” and a damaged QR appeared. Counterfeit complaints dropped 90%. - Serial + Warehouse Management:
In 2024, Bosch Germany added 16-digit serial numbers and barcodes to VOID labels for auto parts.
Warehouse scanners linked the code to part models and inventory levels; removal displayed “VOID,” improving stock control efficiency by 40%.
Application Value:
Goes beyond tamper prevention to support brand marketing, supply-chain visibility, and compliance traceability, achieving “one label, multiple functions” — reducing the need for separate tracking tools, ideal for brand-driven and large-scale enterprises.
