Tamper-proof stickers are one of the easiest ways to protect products from theft or misuse. You’ve likely seen them on electronics, medicine boxes, and sealed packaging. But not all security labels work the same. Some stickers may fracture, reveal “VOID” messaging, or embed serial codes to deter tampering.
This guide walks you through the different types of tamper-proof stickers, their real-world applications, and how to choose the best fit for your products in 2025. About finding the one that protects what matters, we’ll cover what to look for and what to avoid!
What Are Tamper-Proof Stickers?
Tamper-proof stickers, also known as security labels, are designed to show clear signs when someone tries to open or move a product. They work by breaking into pieces, leaving behind a “VOID” message, or adhering so strongly that peeling them off damages either the sticker or the product surface.
These labels don’t stop tampering outright. But they make every attempt visible, helping protect your brand and your customers. The tamper technology behind these stickers depends on clever material and adhesive design. They work across many surfaces—glass, plastic, and cardboard. This makes them versatile tools in pharmaceuticals, electronics, food, cosmetics, and more.
6 Common Types of Tamper-Proof Stickers
Tamper-proof stickers come in several forms. And the right type depends on how the label needs to work and what kind of protection your product needs. Below are six common types and how each one functions.
1. Void Labels
Void labels are designed to leave behind a visible message, like “VOID” or a custom pattern, when someone tries to peel them off. This message appears either on the product surface, the label itself, or both, making any removal attempt obvious. They’re widely used in electronics, logistics, and packaging where seal integrity is critical. Once removed, the label can’t be reapplied without showing signs of tampering.
These labels rely on a dual-layer construction. When pulled, the top layer separates and exposes the hidden print embedded in the bottom layer or adhesive. Some versions leave residue, while others are residue-free for clean surfaces. They work well on plastic, metal, and paperboard and are often compliant with packaging regulations in sensitive industries like healthcare.
2. Destructible (Egg Shell) Labels
Destructible labels, commonly called eggshell stickers, are made from brittle materials that crack and break apart when tampered with. They’re designed so you can’t peel them off in one piece. Instead, the label fractures into small shards, making reapplication impossible and cleanup difficult. These are especially useful in preventing return fraud and warranty abuse.
The label material is ultra-thin and pressure-sensitive, allowing it to conform to uneven or curved surfaces. Once applied, the adhesive cures over time, forming a bond that’s stronger than the label material itself.
Any removal attempt causes the label to tear from multiple points. This makes them ideal for use on electronics, tools, and asset tracking applications where physical evidence of tampering is key.
3. Holographic Security Labels
Holographic labels add a layer of visual complexity that’s hard to replicate. They use reflective foil and layered imaging to create a shimmering, multi-angle effect. This makes them highly visible and useful for verifying product authenticity at a glance. Because of their eye-catching look, they’re often used on luxury goods and branded electronics.
Beyond visual appeal, holographic labels can also include tamper-evident features. Some versions break apart or show hidden messages when removed. Others combine holograms with serial numbers, barcodes, or microtext for added verification. This dual purpose—authentication and tamper resistance—makes them a smart choice for high-risk, high-value items.
4. Transparent Seal Labels
Transparent seal labels are commonly placed over box flaps, bottle caps, or product openings. They’re clear and low-profile, which helps preserve packaging design while still offering tamper visibility. If someone opens the package, the label typically tears or wrinkles, making it obvious the item has been accessed. This subtle design works well in retail and cosmetic packaging.
Many transparent labels use special adhesives that leave a mark or destroy the film upon removal. Some are pre-slit or micro-perforated to tear under pressure. Brands often print their logo, batch number, or subtle patterns onto the film for added traceability. These labels are a discreet yet effective solution for preserving product integrity on store shelves.
5. Color-Changing Labels
Color-changing labels react to specific triggers like heat, pressure, or UV light. These changes serve as visual proof that tampering has occurred. For example, a label might shift from white to red if exposed to high temperatures or physical pressure. This type is especially useful for items sensitive to storage conditions or handling.
These labels are often used in pharmaceuticals, food packaging, or tech, where improper handling can impact safety or performance. The technology is built into the ink or adhesive layer. Once triggered, the color change is permanent, signaling that the product may no longer be secure. It’s a simple, effective way to monitor product history without complex systems.
6. QR/Serial-Enabled Labels
QR and serial-enabled labels link physical products to digital tracking systems. Each label carries a unique code that can be scanned to verify origin, shipment details, or warranty status. This adds traceability and helps prevent counterfeiting, especially in online sales and large distribution networks.
These labels can also log scan history, so you can detect suspicious activity, like multiple scans in different locations. Some are paired with mobile apps for quick authentication by customers or inspectors. Combined with tamper-evident features, these smart labels offer both physical and digital security. They’re commonly used in electronics, healthcare, and high-end retail.

Industries That Rely on Tamper-Proof Stickers
The demand for tamper‑proof stickers spans multiple industries, each with its own regulatory pressures, product risks, and customer expectations. Many sectors now rely on labels with built-in breach detection, serial codes, or authentication features to meet compliance or maintain trust.
Industries using tamper‑proof stickers include:
- Pharmaceuticals & Healthcare: Over 85 % of pharmaceutical manufacturers have adopted advanced security labels—like serialized, tamper‑evident, and induction-seal labels—to fight counterfeit drugs and meet FDA/EMA regulations.
- Food & Beverage: Leading companies now use tamper‑evident labels—shrink bands, induction seals—on approximately 70 % of packaging globally to prevent contamination and food fraud.
- Electronics & Tech: Labels are widely deployed for warranty protection and fraud prevention in high-value items; electronics account for roughly 12 % of tamper‑proof label usage, including destructible and holographic versions.
- Cosmetics & Skincare: This sector favors discreet, branded tamper‑proof seals—like transparent or holographic types—driven by consumer demand for visible authenticity and shelf safety.
- Apparel & Retail: Security labels are used to block fake goods, track batches, and reassure buyers—especially in resale markets—helping verify authenticity across supply chains.
However, you need to know that tamper-proof labels aren’t one-size-fits-all. What works for a tech product may not suit a medical package; your needs guide the choice.
How to Choose the Right Tamper-Proof Sticker for Your Needs?
Before choosing a tamper-proof sticker, think about where and how it will be used. The wrong choice can lead to poor adhesion or weak protection. Here’s what to consider.
Product Surface (Glass, Plastic, Box, Bottle)
Start by checking what surface the sticker will go on. Glass, plastic, metal, or cardboard all need different adhesives. A tamper-proof sticker that works on a plastic bottle may not stick well on a rough box. Matching the sticker to the surface ensures it won’t peel off or lose its effect over time.
Level of Security Needed (Visual Deterrent vs Forensic Traceability)
Decide how much protection your product needs. If you want visible proof of tampering, go for void labels or holograms. But if you need deep tracking, forensic features, or serial codes, it might be better. The right level of security depends on your product’s risk and business goals.
Industry Compliance (e.g., FDA, ISO, CE Marking)
Some industries require specific label types to meet legal standards. For example, FDA or ISO rules may apply to medical or food items. Make sure your tamper-proof sticker meets these compliance marks. Skipping this step can lead to delays, fines, or product recalls.
Adhesive Strength and Environmental Resistance
Think about storage and shipping conditions. If your product faces heat, cold, moisture, or friction, you’ll need strong adhesives. Choose tamper-evident labels designed for that level of stress. A weak sticker in a harsh environment can lose grip, fail, or fall off.
Customizing Your Tamper-Proof Labels
The best sticker is one that fits both your product design and security goal. Custom options help you match both form and function without breaking your budget.
Start with the basics: shape, size, and color. Labels can be shaped for bottles, caps, boxes, or pouches. A good fit helps prevent peeling in transit.
Next is branding. You can add your logo, company pattern, or even a unique design that’s hard to copy. This not only supports product safety but also builds trust with buyers through visible evidence of authenticity. For products that require track-and-trace control, use serial numbers or variable data.
Barcodes, QR codes, and batch info can help you track every item from production to shelf, which is key for industries like pharma and electronics.
If you need a higher level of protection, consider smart features. NFC chips, UV ink, and covert messages are harder to duplicate and give you another layer of tamper resistance. These are often used in high-risk sectors or high-value goods.
Last, choose a certified supplier. Look for ISO or FDA-compliant producers with experience in your industry. That helps you avoid poor adhesive quality or printing issues that could break down during use and risk your operations or brand image.
Real-World Use Cases
Tamper-evident stickers aren’t just about security—they help protect your brand and reduce risks that come with shipping, retail, or online sales. Companies across industries use them to build buyer trust and limit losses from fraud or contamination. Here are a few ways different sectors put them to use:
- Medtronic (medical devices) – Uses serial void stickers on packaging to support traceability and compliance during transportation and storage. These tamper-resistant seals offer visible evidence if the packaging is disturbed.
- Amazon Renewed (tech/e-commerce) – Uses breakable seals on refurbished electronics to reduce warranty scams. If a customer tries to tamper with the product, the label leaves a clear mark, protecting Amazon from false claims.
- Nestlé (food and beverage) – Rolled out tamper-evident caps and neckband seals on bottled drinks and baby formula. These seals show if a package was opened before sale, helping improve shelf trust.
