1. What Is a VOID Label?
A VOID label is a tamper evident security label that displays a hidden message—such as “VOID,” “OPENED,” or a custom warning—when someone attempts to peel it off. The message appears either on the surface or on the label itself, depending on the label type.
These labels are designed to prevent unauthorized access, protect product integrity, and indicate tampering in a visible and irreversible way. Once applied, they cannot be removed or repositioned without showing signs of disturbance.
VOID labels are widely used in industries such as electronics, pharmaceuticals, government documents, logistics, and retail packaging. Common substrates include PET, destructible vinyl, and aluminum foil, and labels can be finished with custom die cuts, barcodes, serial numbers, or holographic elements for added authentication and traceability.
They are available in:
- Full-transfer (leaves “VOID” on the surface)
- Partial-transfer (message appears both on label and surface)
- Non-transfer (only shows VOID on the label)
With increasing concerns around product tampering, counterfeiting, and security breaches, VOID labels serve as a simple yet powerful solution to assure customers, maintain compliance, and protect brand reputation.
Current Situation
VOID labels are widely applied in industries such as electronics, pharmaceuticals, government documents, logistics, and retail packaging. Common substrates include PET, destructible vinyl, and aluminum foil.
Labels can also be processed with custom die cuts, barcodes, serial numbers, or holographic elements to enhance authentication and traceability. With growing concerns about product tampering, counterfeiting, and security breaches, VOID labels have become a simple yet powerful solution to assure customers, maintain compliance, and protect brand reputation.
Future Development Outlook
In the future, VOID labels are expected to integrate with more advanced technologies. For example, they may combine with IoT (Internet of Things) to achieve real-time monitoring of label status. Once tampered with, the label could immediately send alerts to the system.
Additionally, VOID labels may be incorporated into blockchain solutions, creating an immutable traceability record for each label and further strengthening product security and brand protection.
From a market perspective, as global awareness of product safety and brand protection continues to rise—especially in fields such as luxury goods and medical supplies—the demand for VOID labels will steadily grow, driving technological innovation and expanding application scenarios.
Applications
VOID labels are primarily used to prevent unauthorized opening or tampering of products, ensuring the integrity of goods throughout the supply chain—from production to delivery. In the electronics industry, they are applied to high-end product packaging to prevent tampering during transportation or storage. In the pharmaceutical sector, they ensure medicine packaging remains intact, safeguarding drug safety.
For government documents, VOID labels help prevent unauthorized access or alterations. In logistics, they are applied to parcels or shipping cartons to verify that goods have not been opened during transit. In retail packaging, VOID labels protect high-value products, allowing consumers to instantly identify whether an item is sealed and authentic.
Production Process
The production of VOID labels begins with selecting appropriate substrates such as PET, destructible vinyl, or aluminum foil—materials that must reveal hidden information when tampered with. Next, specialized printing techniques are applied to embed hidden messages such as “VOID” or “OPENED”, or custom warnings.
Additional elements like custom die cuts, barcodes, serial numbers, or holograms can be integrated to strengthen authentication and traceability. Adhesive coating is then applied to ensure the right level of stickiness, allowing the labels to bond firmly to surfaces.
Finally, the finished products undergo strict quality testing to verify adhesion strength, clarity of tamper evidence, resistance to temperature variations, and anti-aging performance. Once approved, they are mass-produced and packaged for delivery.
2. Why VOID Labels Matter
In today’s hyper-connected global supply chains, products move from factories in China to store shelves in New York, or from pharmacies in Berlin to patients in Madrid—all in tightly coordinated steps.
Product security is no longer a “nice-to-have” option—it’s a critical foundation for brand trust, consumer safety, and regulatory compliance. As a cornerstone of tamper-evident solutions, VOID labels play an irreplaceable role across industries. Below, we highlight their essential value with real-world examples and data.
🔒 1. Instant Tamper Detection and Traceability
The core function of VOID labels is to leave an irreversible and visible sign of tampering. When peeled, repositioned, or tampered with, these labels clearly display a “VOID” message or adhesive residue—making it impossible to reseal undetected.
Real-world example: Pharmaceutical Distribution Crisis (USA, 2022)
A U.S.-based generic drug manufacturer faced a serious threat in 2022 when over 300 bottles of blood pressure medication stored in a Florida warehouse were secretly opened and replaced with sugar pills—then resealed.
After this, the company adopted our semi-transfer VOID labels, sealing both the bottle cap and neck. Six months later, during routine inspections, a staff member spotted faint “VOID” marks on a bottle and flagged it.
Investigation revealed an internal employee’s tampering attempt. The label prevented a potential $2.4M FDA recall, and protected patient safety.
🧪 2. Ensuring Regulatory Compliance
Global regulations increasingly mandate tamper-evident packaging, especially in high-risk sectors. VOID labels offer the most cost-effective route to compliance. Failing to meet these standards can result in heavy fines, recalls, or loss of market access.
Real-world example: Food Exports to the EU (Mexico, 2021)
A Mexican organic snack brand had their shipment of tortilla chips rejected at Hamburg Port. According to EU Regulation (EC) No 178/2002, all prepackaged food must have visible tamper-evident features. The brand had used standard tape—deemed non-compliant.
This led to an €80,000 loss in inventory and shipping costs, plus a 3-month market entry delay.
The company later adopted our ISO 22382-compliant VOID labels with EU certification. Since then, all 12 subsequent shipments passed customs without issue.
In pharmaceuticals, compliance is stricter: FDA fines for packaging violations can reach $1.2 million per instance. Our certified VOID labels have enabled clients to maintain zero-risk operations.
🤝 3. Reinforcing Product Integrity and Consumer Trust
According to Nielsen 2023, 68% of consumers consider product authenticity a key purchase driver. VOID labels go beyond tamper-proofing—they signal that your brand values safety and quality, fostering trust that translates to repurchase and loyalty.
Real-world example: Electronics Reseller Boosts Loyalty (Singapore, 2024)
A Singapore-based electronics reseller struggled with low repeat purchases due to concerns over product tampering. They began applying custom VOID labels to serial number stickers and box seals, with a clear message:
“If the ‘VOID’ mark appears, the device has been opened—please request a replacement.”
Within 6 months, repeat purchase rates rose from 22% to 41%, and positive reviews citing “trust” and “authenticity” jumped 57%.
Internally, the label also deterred tampering: one staff member was caught trying to swap batteries, but the VOID mark exposed the attempt immediately—preventing damage to the brand and consumers.
💡 4. Empowering Anti-Counterfeit and Traceability Efforts
VOID labels can be customized with barcodes, QR codes, batch numbers, or holographic patterns—enabling full supply chain traceability and making it easier to identify counterfeit goods.
Real-world example: Automotive Aftermarket Brand Defeats Counterfeiting (China/Thailand)
A Chinese brake pad manufacturer was losing $1.2M annually due to counterfeits in Southeast Asia. Fake parts with the brand’s logo caused multiple safety incidents.
They partnered with us to create blockchain-linked VOID labels. Each QR code was tied to batch, production date, and authorized distributor info.
In one case, a Thai mechanic scanned a label and found mismatched data. Authorities traced the fakes to a warehouse in Bangkok, where 10,000 fake products were seized—shutting down the counterfeiting ring.
Logistics teams also benefited: a missing carton in an Australian shipment was located within 2 hours by scanning a VOID label, versus the 2 days a manual trace would take.

3. Types of VOID Labels
VOID labels come in various types based on how the tamper-evident message is revealed. Choosing the right type depends on your packaging surface, security level, and removal sensitivity.
| VOID Label Type | How It Works | Typical Applications |
|---|---|---|
| Full-Transfer | Leaves the entire VOID message on the application surface when removed | Carton boxes, shipping labels, outer packaging |
| Partial-Transfer | Splits message between label and surface; both show signs of tampering | Asset tags, electronics packaging, warranty protection |
| Non-Transfer | VOID message appears only on the label; no residue left on surface | Glass, metal, retail items, leased equipment |
✅ Tip: If your packaging is high-value and reused (e.g., leased hardware or rental kits), use non-transfer VOID labels to avoid surface damage.

4.Manufacturing Process of VOID Tamper Evident Labels
The creation of a VOID tamper evident label is a perfect fusion of material science, precision engineering, and security demands. Every label goes through multiple meticulous steps with one core objective: to ensure irreversible tamper evidence, stable performance, and reliable functionality across complex global supply chains. Below is the full production process, explained with technical details and real-world use cases.
1. Substrate Selection: Matching the “Skeleton” to the Application
The substrate acts as the “skeleton” of the label, directly determining its durability, tear resistance, and application suitability. We carefully select the substrate based on the customer’s actual use scenario:
- PET Film for Standard Applications: PET is the most commonly used substrate, offering excellent tear resistance, abrasion resistance, and waterproof performance. It adapts well to most packaging surfaces such as cartons or plastic bottles. For example, PET is ideal for sealing e-commerce parcels to withstand friction and moisture during international shipping, ensuring the tamper-evident feature remains intact.
- Destructible Materials for High-Security Applications: For ultra-sensitive industries like pharmaceuticals or precious metals, we use destructible vinyl or ultra-fragile films. For example, when applying VOID labels to vaccine vials, destructible film is used — once someone attempts to remove the label, it breaks into tiny fragments, physically preventing reapplication and tamper concealment.
- Custom Substrates for Harsh Environments: For high-temperature workshops (e.g., automotive parts factories) or cold storage scenarios (e.g., cold-chain food logistics), we use modified PET with high/low-temperature resistance to ensure the label remains adhesive from -40°C to 80°C without curling or detachment.
2. Adhesive Coating: Firm Bonding with Tamper Evidence
Adhesive is critical to achieving “tamper evidence.” We use pressure-sensitive adhesives (PSAs) engineered to stick firmly and leave a clear VOID pattern upon removal:
- Custom Adhesive Formulas Based on Surface: For paper cartons or corrugated surfaces, we use medium/low tack adhesives to ensure VOID patterns transfer cleanly without damaging the packaging. For smooth surfaces like glass (medicine bottles) or metal (electronics), we use high-tack adhesives that both adhere securely and activate the VOID transfer upon peeling.
- Specialty Adhesive Enhancements: For cold-chain food packaging, we incorporate anti-low-temperature additives. For chemical products, we use adhesives resistant to acid/base corrosion. One pesticide manufacturer previously experienced adhesive failure due to chemical exposure. After we customized the adhesive formula, the issue was fully resolved.
3. VOID Message Activation: The “Invisible Trigger Mechanism”
This is the soul of the VOID label — the process that makes the “VOID” message (or custom security text) invisible under normal conditions and appear upon tampering.
- Mainstream Technique: Release Coating + Laser Etching: A release layer is applied on the back of the substrate, on which VOID, “Opened,” or brand-specific warnings are printed using high-precision printers. Laser etching then defines the edges to ensure a clean transfer during removal. For luxury brands, the VOID label may include a custom logo and VOID pattern, enhancing both security and brand identity.
- For High-Precision Applications: Micro-Embossing Technology: In sensitive use cases like electronic chips or high-end medical devices, we use micro-embossing — VOID patterns are molded into the adhesive layer at the micron level. They remain invisible to the naked eye and only appear upon separation due to bonding stress, avoiding any scratches from laser etching.
- Multilingual & Graphic Customization: For cross-border e-commerce clients, we integrate multilingual warnings such as “VOID” + English/Chinese/local language, ensuring clear tamper indicators across markets. For military clients, we combine VOID patterns with proprietary security graphics for higher-level protection.
4. Surface Coating and Post-Processing: Protection, Branding & Compliance
This step protects the core structure of the label while supporting branding and regulatory needs — combining functionality and appearance.
- Surface Lamination: A clear layer (glossy, matte, or scratch-resistant) is applied to the top surface. Glossy laminates are ideal for showing logos; matte is preferred for pharmaceutical or food labels requiring traceability codes without glare. For outdoor equipment tags (e.g., construction machinery), scratch-resistant films protect against abrasion.
- Custom Printing for Branding & Compliance: We can print logos, QR codes, batch numbers, production dates, and certification marks (FDA, CE). For example, labels for pharma clients are printed with drug batch info and traceable QR codes, with reserved areas for regulatory marks. For electronics brands, we integrate the logo with the VOID pattern for dual purpose: security and exposure.
- Environmental Resistance Treatment: For automotive parts labels exposed to sunlight, we apply UV-resistant coatings to prevent fading. For sea shipments, moisture-resistant treatment is used to combat humidity and salt corrosion.
5. Die-Cutting and Rewinding: Supporting Manual & Automated Use
The final step is converting finished materials into user-friendly formats suitable for both hand application and automated labeling lines.
- Precision Die-Cutting: Labels are cut to specified shapes/sizes — rectangles for shipping boxes, circles for medicine caps or devices, or custom shapes (e.g., lipstick tubes, logos). For example, we once customized arc-shaped labels for a beauty brand’s lipstick packaging to ensure smooth adhesion to curved surfaces.
- Roll or Sheet Conversion: For mass production lines, labels are wound into standard-size rolls (e.g., 25mm/50mm width, 1000m per roll) compatible with labeling machines. For small businesses or laboratories, labels are supplied in sheets or small rolls (e.g., 500 pcs per pack, 100m per roll) for manual use.
- Edge Finishing: Rounded corners or polished edges prevent the label from snagging or tearing during transport or use. This is especially crucial for logistics labels to minimize damage in transit.
