What Is a Security Label?

A security label is a specially designed adhesive label used to indicate whether a product, package, component, or enclosure has been opened or tampered with.

 

Unlike a conventional product sticker, a security label is designed around a specific security response.

 

Depending on the construction, removing the label may:

●Leave a visible VOID or OPEN message

●Transfer a security pattern to the surface

●Separate part of the label

●Destroy the label

●Break into fragments

●Reveal a hidden pattern

●Change the appearance of the label

●Provide visible evidence that the original seal has been disturbed

 

This makes security labels useful in situations where businesses need a simple visual indication of interference.

 

The label itself does not necessarily prevent someone from opening a package. Its primary purpose is to make unauthorized opening or removal more apparent.

 

For B2B buyers, this distinction matters.

 

The correct question is not simply, "Which security label is strongest?"

 

A better question is:

What should happen when someone tries to remove the label?

That answer determines whether a total transfer, partial transfer, non-residue, VOID, destructible, or holographic construction is appropriate.

 

Custom Security Labels for B2B Product Protection

A security label can be a small component of a product, but it often has to meet several requirements at the same time.

 

A buyer may need:

●Tamper evidence

●Reliable adhesion

●Clean application

●Custom dimensions

●Brand printing

●Serial numbers

●Variable information

●Barcode or QR code printing

●Specific colors

●Special security patterns

●Suitable packaging

●Stable production quality

●Bulk manufacturing

 

This is why commercial security label production is different from ordinary sticker printing.

 

The label material, adhesive, release liner, printing method, security construction, die-cutting process, and final packaging all need to work together.

 

SEALTAPE's current product range includes customized security labels for warranty protection, electronics, phone repair, cosmetics, screws, and other applications. The existing category also includes total transfer, partial transfer, and non-residue security label products.

 

Types of Security Labels

Different security label constructions provide different tamper-evident effects.

Choosing the right type depends on the surface, required security effect, removal behavior, product value, application environment, and target price.

 

Total Transfer Security Labels

A total transfer security label is designed so that, when someone attempts to remove it, the security layer transfers from the label onto the applied surface.

 

The result can leave a visible pattern, message, or security indication on the package or product.

 

This construction is useful when the buyer wants clear evidence that the original seal has been disturbed.

 

●Typical applications include:

●Product packaging

●Cartons

●Electronics

●Warranty protection

●Boxes

●Asset protection

●High-value products

●Security seals

 

A total transfer security label can also be customized with a company logo, security wording, colors, dimensions, and other design elements.

 

When Should You Choose Total Transfer Labels?

Choose a total transfer construction when the main objective is to create a clear physical indication on the protected surface after attempted removal.

 

It can be a good choice for packaging where the buyer wants the tamper evidence to remain visible even after the original label has been removed.

 

Partial Transfer Security Labels

Partial transfer security labels are designed so that part of the security construction transfers or separates during removal.

 

This can create a visible change without necessarily transferring the entire security layer.

 

Partial transfer designs are often selected when a buyer wants a balance between:

●Tamper evidence

●Label appearance

●Application requirements

●Cost

●Removal behavior

 

Partial Transfer Security Label Applications

Common applications can include:

●Warranty labels

●Electronics

●Packaging

●Product sealing

●Components

●Boxes

●Retail products

 

The exact effect depends on the material combination and construction selected for the project.

For a new OEM product, testing the label on the actual application surface is recommended before bulk production.

 

Non-Residue Security Labels

A non-residue security label is designed for applications where visible tamper evidence is required but excessive adhesive residue on the protected surface is undesirable.

 

This can be especially useful for products with smooth or finished surfaces.

 

Typical applications include:

●Electronics

●Mobile phones

●Cameras

●Computer equipment

●Consumer electronics

●Repair services

●Components

●High-value devices

 

Why Use a Non-Residue Security Label?

Some products cannot tolerate adhesive residue.

 

For example, an electronics manufacturer may need to protect an access point or enclosure while avoiding unnecessary adhesive contamination after removal.

 

The important point is that "non-residue" does not simply mean a label that peels away easily. The label still needs to provide the intended security effect.

 

The construction should therefore be tested against:

●Surface type

●Surface finish

●Application temperature

●Storage conditions

●Required adhesion

●Removal conditions

●Desired tamper evidence

 

VOID Security Labels

VOID security labels are among the most recognizable types of tamper-evident labels.

When the label is disturbed or removed, a VOID, OPEN, or similar security message can become visible.

 

Depending on the construction, the message may appear:

●On the label

●On the substrate

●Through a transfer effect

●Through separation of the security layer

VOID labels are widely used because the security effect is easy for operators and customers to understand.

 

VOID Security Label Applications

VOID labels can be used for:

●Warranty seals

●Electronic equipment

●Phone repair

●Packaging

●Cartons

●Cosmetic packaging

●Product enclosures

●Security closures

●Components

Custom VOID Messages

The security message does not always need to be the standard word "VOID."

Depending on the design, a brand may request:

●VOID

●OPEN

●OPENED

●SEALED

●CHECK

●CUSTOM TEXT

●Brand name

●Logo

●Pattern

For private-label projects, the message and security pattern can be incorporated into the overall label design.

Warranty Security Labels

Warranty security labels are used to show whether a product or component has been opened, disassembled, or otherwise interfered with.

They are commonly used by:

●Electronics manufacturers

●Repair companies

●Distributors

●Computer brands

●Appliance manufacturers

●Mobile phone service providers

●Equipment suppliers

 

A warranty label can contain:

●Brand logo

●Warranty wording

●VOID message

●Serial number

●Date code

●Barcode

●QR code

●Security pattern

The purpose is straightforward: the business needs an easy way to identify whether the original warranty seal has been disturbed.

Electronics Security Labels

Electronics are particularly sensitive to the choice of security label.

A label may need to adhere to:

●Plastic housings

●Metal surfaces

●Painted surfaces

●Glass

●Electronic enclosures

●Components

 

At the same time, the manufacturer may want a clear tamper indication without damaging the appearance of the device.

Potential applications include:

●Smartphones

●Cameras

●Computers

●Servers

●Networking equipment

●Consumer electronics

●Electronic components

●Repairable equipment

For electronics, buyers should evaluate both the security effect and the removal behavior before mass production.

Phone Repair Security Labels

Phone repair businesses often need small security labels that fit around screws, covers, connectors, or other access points.

 

A phone repair security label may be used to:

●Indicate whether a device has been opened

●Protect a screw

●Identify a repair center

●Support warranty management

●Discourage unauthorized disassembly

For small electronics, accurate die cutting is particularly important because the available application area can be limited.

Cosmetic Security Labels

Cosmetic products often require a combination of appearance and security.

A label used on cosmetic packaging should not look like an industrial seal if the brand is positioned around premium presentation.

At the same time, it may need to show whether the package has been opened.

 

Applications can include:

●Skincare

●Beauty products

●Cosmetic boxes

●Bottles

●Jars

●Gift sets

●Personal care products

For cosmetic brands, customization can include label shape, color, logo, surface finish, security message, and packaging.

Screw Security Labels

A screw security label is designed to cover or bridge a screw or fastening point.

The objective is usually simple: if someone removes or interferes with the screw, the security label should show evidence of the attempt.

 

Typical applications include:

●Electronic housings

●Appliances

●Equipment

●Control panels

●Devices

●Machinery

●Consumer products

Small labels like these require careful control of die-cutting and dimensions.

Hologram Security Labels

Hologram security labels combine tamper evidence with visual authentication features.

They can use holographic effects to make a label more difficult to reproduce using ordinary printing.

 

Holographic labels can be used for:

●Brand protection

●Authentication

●Product packaging

●Certificates

●Documents

●Electronics

●Premium products

●Anti-counterfeit programs

For projects that require both tamper evidence and visual security, a holographic construction may be considered.

Destructible Security Labels

Destructible labels are designed to break apart when someone attempts to remove them.

Instead of allowing the complete sticker to be peeled away in one piece, the material can fracture into small pieces.

This makes reuse difficult.

Destructible labels are useful when the buyer wants the security label itself to become visibly damaged during removal.

 

Typical applications include:

●Warranty labels

●Asset labels

●Equipment protection

●Product authentication

●Electronics

●Packaging

Security Label Materials

The security mechanism is only one part of a label.

 

The material also affects:

●Appearance

●Flexibility

●Print quality

●Durability

●Adhesion

●Die-cutting

●Tamper behavior

●Cost

Different projects require different material constructions.

PET Security Labels

PET can provide a smooth and stable surface for printed security labels.

 

It may be suitable for applications requiring:

●Clean graphics

●Dimensional stability

●A modern appearance

●Durable label construction

Paper Security Labels

Paper can be a practical choice for certain packaging and general-purpose security applications.

It can also provide a different visual appearance from plastic films.

 

Paper security labels may be considered when:

●Printing is important

●The application is primarily indoors

●Cost is a major factor

●A paper appearance is preferred

Synthetic Paper Security Labels

Synthetic paper combines some characteristics of paper with properties associated with synthetic substrates.

It can be useful when the buyer wants a printable surface with improved resistance compared with conventional paper.

PP Security Labels

Polypropylene can be used in applications where a flexible plastic film is preferred.

PVC Security Labels

PVC has historically been used in a range of label and sticker applications.

 

For a security label project, the material should be selected according to the customer's environmental, regulatory, printing, and application requirements.

BOPP Security Labels

BOPP can provide a smooth film surface and is commonly used for printed labels and packaging applications.

Security Label Construction

A security label is usually more than just a printed piece of material.

 

A typical construction can involve:

 

Face Material → Printed Security Layer → Tamper-Evident Layer → Adhesive → Release Liner

 

The exact construction varies by product.

Some designs require a transfer layer. Others require a destructible face material. Some applications prioritize clean removal. Others require strong evidence after tampering.

 

This is why a supplier should not recommend a security label only from the requested size. The supplier should understand the actual application.

How Security Labels Work

The key difference between security labels and conventional labels is the behavior of the label during removal.

 

Total Transfer

The security layer transfers to the surface.

 

Partial Transfer

Part of the security layer transfers or separates.

 

Non-Residue

The label is designed to provide tamper evidence while minimizing unwanted adhesive residue on the protected surface.

 

VOID

A message or pattern becomes visible when the label is disturbed.

 

Destructible

The label breaks into pieces when removal is attempted.

 

Holographic

The label incorporates a visual security feature that can support authentication and brand protection.

 

These mechanisms can also be combined.

 

For example, a brand may want:

VOID + Custom Logo + Holographic Effect + Variable Number

 

The final construction should be developed around the security objective rather than simply adding features for the sake of them.

Security Label Comparison

Security Label Type	Main Security Effect	Residue Behavior	Typical Applications
Total Transfer	Security layer transfers to surface	Depends on construction	Packaging, electronics, warranty
Partial Transfer	Part of security layer transfers	Depends on construction	Warranty, product sealing
Non-Residue	Visible tamper evidence with low-residue objective	Minimal / controlled	Electronics, devices
VOID Label	VOID or OPEN message becomes visible	Depends on construction	Warranty, packaging
Destructible Label	Label breaks during removal	Depends on adhesive	Electronics, assets, packaging
Hologram Label	Visual authentication effect	Depends on construction	Brand protection, premium products

 

This comparison is only a starting point.

 

The same security mechanism can behave differently depending on the substrate, adhesive, surface finish, temperature, storage conditions, and removal method.

1. What Surface Will the Label Be Applied To?

Possible surfaces include:

Cardboard

Paper

Plastic

Glass

Metal

Painted metal

Electronics housings

Packaging film

 

2. What Should Happen During Removal?

Should the label transfer, split, reveal a message, break apart, or leave the surface relatively clean?

 

3. Is Residue Acceptable?

If the label is applied to an electronics housing, a large amount of adhesive residue may be undesirable.

 

4. Does the Product Need a VOID Message?

If operators need a quick visual signal, a VOID or OPEN message can be useful.

 

5. Is Brand Protection Required?

Consider:

Holograms

Custom patterns

Variable numbers

QR codes

Serialized labels

Special printing

 

6. What Environment Will the Label Face?

Consider:

Temperature

Humidity

UV exposure

Handling

Transportation

Storage

What is a tamper-evident security label?

A tamper-evident security label is designed to show a visible change after an attempted removal or opening. The effect may include a VOID message, transfer, separation, destruction, or another visible indication.

 

What is a VOID security label?

A VOID security label reveals a VOID, OPEN, or similar message when the label is disturbed or removed, depending on its construction.

 

What is a total transfer security label?

A total transfer security label transfers its security layer or message to the protected surface when removal is attempted.

 

What is a partial transfer security label?

A partial transfer security label is designed so that part of the security construction transfers or separates when the label is removed.

 

What is a non-residue security label?

A non-residue security label is designed for applications where tamper evidence is required while minimizing unwanted adhesive residue on the protected surface.

 

Can security labels be customized?

Yes. Security labels can be customized in size, shape, color, printing, security message, logo, and other specifications depending on the product construction.

 

Can you print our company logo?

Custom branding can be incorporated into security label designs. Depending on the construction, logos can be combined with security messages, patterns, serial numbers, QR codes, or other printed elements.

How do I choose between total transfer and non-residue labels?

Start with the required removal behavior. If you want the security layer to remain clearly transferred to the protected surface, total transfer may be appropriate. If the product surface must remain relatively clean while still showing tampering, a non-residue construction may be more suitable. The actual application should be tested before final selection.

Custom Security Labels for Your Product

A security label may be small, but the specification behind it is not.

The right product depends on the surface, adhesive, material, security mechanism, dimensions, printing, application environment, and the level of tamper evidence required.

For one customer, a simple VOID warranty sticker may be enough.

Another customer may need a small non-residue label for an electronic device.

A packaging company may require total transfer labels in large rolls.

A brand protection project may combine a customized logo, holographic effect, serial number, and QR code.

These are different products even though they all fall under the broad category of security labels.

SEALTAPE works with international B2B buyers to develop security labels around these different requirements, with a product range covering total transfer, partial transfer, non-residue, VOID, warranty, electronics, phone repair, cosmetic, and other customized security label applications.
