What Do Security Labels Look Like? Features, Types, and Examples Explained

Security labels are a vital tool in protecting products, packaging, and businesses from tampering, theft, and counterfeiting. These labels do far more than stick to a surface; they provide reassurance to customers, help meet compliance standards, and offer clear visual indicators that an item is safe, authentic, and untampered. But what do security labels actually look like?

Security labels vary in look but often feature holograms, “VOID” text, barcodes, or tamper-evident cuts. Used to protect packaging and prove authenticity, they help prevent tampering and counterfeiting.

In this guide, we explore their features, types, and real-world applications to help you choose the best solution for your business.

What Are Security Labels?

Security labels are specially designed adhesive labels used to indicate tampering, authenticate products, and deter unauthorised access or counterfeit activity. They are frequently used in industries such as pharmaceuticals, electronics, logistics, food and beverage, cosmetics, and retail.

These labels are made from materials that provide visible or irreversible signs of interference when someone attempts to remove or tamper with them. Whether through tamper-evident technology, serial numbers, holography, or destructible materials, security labels act as a strong deterrent against fraud and misuse.

What Do Security Labels Look Like?

There is no one-size-fits-all answer; security labels vary widely in appearance depending on their function and industry use. However, some common visual characteristics include:

• Holographic effects: Reflective surfaces with colour shifts and custom logos that are difficult to replicate.

• “VOID if removed” backing: These labels leave a residue or a clear message if peeled off.

• Destructible material: Some break into fragments if removal is attempted.

• Barcodes or QR codes: These allow for scanning and verification.

• Serial numbers or batch codes: Unique identifiers for tracking purposes.

• Tamper cuts or perforations: Built-in features that prevent clean removal.

• Transparent or coloured films: Depending on product branding or discretion needs.

Aesthetically, security labels range from minimal and professional to highly branded and visually striking. Their look is often customised to match the company’s brand identity while still fulfilling their security function.

Common Features of Security Labels

Security labels often include a combination of the following features to provide both visible deterrence and traceability:

• Tamper-Evident Adhesives: Once applied, they cannot be removed without leaving clear evidence.

• VOID Messaging: Reveals a hidden message or pattern when peeled.

• Holographic Foils: Offer unique patterns that reflect light and are hard to replicate.

• Serialisation: Unique numbers, codes, or barcodes for traceability.

• UV or Invisible Inks: Only visible under specific lighting conditions.

• Custom Printing: Logos, colour schemes, and brand-specific elements can be added.

• Destructible Vinyl or Acetate Materials: Fragments into pieces if tampered with.

These features help maintain product integrity, build consumer trust, and meet industry-specific compliance standards, such as those outlined by the British Standards Institution (BSI).

Types of Security Labels

There are several types of security labels, each offering different levels of protection and use cases:

1. Tamper-Evident Labels

These labels show clear signs of interference. They may leave behind text like “VOID” or change colour when peeled. Commonly used on medicine boxes, packaging seals, and electronics.

2. VOID Labels

When removed, these leave behind a residue or reveal a warning message on the product or surface, ideal for securing high-value or sensitive goods.

3. Destructible Labels

Designed to tear into pieces if someone tries to remove them. They provide immediate evidence of tampering, often used in warranty protection and retail products.

4. Holographic Security Labels

Eye-catching and extremely difficult to duplicate, these labels contain layered, reflective surfaces that validate authenticity. They are popular for branded items, certificates, and ID documents.

5. Barcode or Serial Number Labels

Used for traceability and inventory management, these labels include unique identifiers that can be scanned and tracked.

6. Custom Security Labels

Tailored to your business, custom security labels can combine several features (e.g., branding, VOID messaging, serialisation, tamper-evident design) to meet unique security needs.

Real-World Examples and Applications

Pharmaceutical Industry

Medicine boxes often use tamper-evident tape that breaks when opened. Holographic labels validate authenticity and prevent counterfeit drugs from entering the supply chain.

Electronics and Gadgets

Laptops, smartphones, and accessories are sealed with destructible warranty labels or VOID stickers to indicate if a device has been tampered with.

Retail Clothing and Footwear

High-value items such as trainers, handbags, and designer wear often have barcode security tags and destructible stickers.

Food and Beverage Packaging

Pre-sealed food containers or drink bottles may carry tamper-evident labels that break or wrinkle when opened, assuring consumers of safety.

Logistics and Courier Services

Shipping boxes use barcode serial labels and VOID tapes to ensure the package hasn’t been opened in transit. These labels also help with inventory tracking.

Cosmetics and Skincare

Beauty products are often sealed with transparent or branded security labels that provide both visual appeal and protection from tampering.

How to Choose the Right Security Label for Your Business

Choosing the right security label depends on various factors:

1. Type of Product or Packaging
   
   

• Fragile products may need a label that doesn’t damage the surface.

• Smooth vs rough packaging materials require different adhesives.
  
  

2. Level of Security Needed
   
   

• High-value goods may require multiple layers of security (e.g. holographic + VOID).

• For everyday items, a simple tamper-evident label may suffice.
  
  

3. Industry Requirements
   
   

• Pharmaceuticals and electronics often have strict labelling standards.

• Food and drink products may need materials safe for contact or temperature-resistant labels.
  
  

4. Branding and Customer Trust
   
   

• Custom designs with logos build trust and brand recognition.

• Holography and serialisation help authenticate premium products.
  
  

5. Budget and Volume
   
   

• Custom features may cost more but offer added value.

• CDM Labels can advise on affordable bulk solutions.
