Recently, many customers have asked us about security labels for packaging protection. There are many types of tamper-evident labels, but one of the most common and practical options is the VOID label. Compared with more complex security packaging solutions, red VOID labels are easy to apply, cost-effective, and suitable for many industries.

For businesses that are just starting to test anti-tamper packaging, void stickers can be a good first step. They usually have a lower MOQ, flexible customization options, and a clear visual warning effect. Whether you need to protect product boxes, seal documents, mark warranty areas, or prevent unauthorized opening, VOID labels can help you quickly improve packaging security.

1. What Are Red VOID Security Labels?

Red VOID Security Labels are a type of tamper-evident label. Once someone tries to remove the label from the product or package surface, the label will show visible “VOID”, “OPENED”, or customized security messages.

This makes the opening attempt easy to identify.

The red color also plays an important warning role. It attracts attention and clearly tells users, warehouse staff, distributors, or end customers that the package is protected. For this reason, tamper evident void labels are often used for anti-opening, anti-return, anti-counterfeiting, and anti-tampering purposes.

Common uses include:

Packaging box sealing
Product warranty protection
Logistics parcel security
Document sealing
Asset management
Electronics protection
High-value goods packaging

2. How Do VOID Security Labels Work?

VOID security labels work through a special film and adhesive structure. When the label is applied to a surface, the adhesive bonds with the object. If someone tries to remove it, the label structure separates and reveals a hidden security message.

The process is simple:

Step 1: Apply the label to the package or product surface.

Step 2: The label bonds to the surface through pressure-sensitive adhesive.

Step 3: If the label is removed, it leaves a visible VOID, OPENED, or custom warning message.

This is why many customers also call them void if opened labels. The label does not need an electronic system or scanner. The tamper evidence appears directly on the surface or on the label itself after removal.

Different label structures create different effects. Some labels transfer the full VOID message to the surface, some create partial transfer, and some show the evidence mainly on the label film without heavily contaminating the product surface.

3. Why Choose Red VOID Labels?

Red VOID labels are popular because they are practical, visible, and easy to customize.

They offer several advantages:

First, the red color gives a strong warning effect. It is easy to notice on packaging boxes, envelopes, electronics, and logistics parcels.

Second, they are easy to apply. Most labels can be supplied in rolls for manual application or automatic labeling.

Third, they are cost-effective. Compared with complex molded seals, RFID solutions, or custom security bags, VOID labels usually have a lower development cost.

Fourth, they support flexible customization. Customers can choose different sizes, shapes, printing designs, serial numbers, QR codes, and security messages.

Fifth, they can be used across many industries. From electronics to logistics, from retail packaging to document protection, VOID labels are one of the most versatile security packaging solutions.

For companies that need a simple but effective anti-tamper solution, void stickers are often the most practical starting point.

4. Types of Red Tamper-Evident VOID Labels

There are several types of red tamper-evident VOID labels. The right type depends on the surface, security level, and application environment.

Full Transfer VOID Labels

Full transfer VOID labels leave the full VOID message on the applied surface after removal. The label itself may also show visible damage.

They are suitable for:

Paper cartons
Plastic boxes
Metal surfaces
Electronic product housings
Logistics packaging
Warranty sealing

This type is useful when customers want strong visible evidence directly on the product or package surface.

Partial Transfer VOID Labels

Partial transfer VOID labels leave part of the VOID message on the surface and part of the evidence on the label film.

They are suitable for:

Packaging seals
Document bags
Pesticide canister sealing
Asset management
Product traceability labels

Partial transfer labels are often used when customers need both security evidence and readable printed information such as serial numbers or QR codes.

Non-Transfer VOID Labels

Non-transfer VOID labels mainly show tamper evidence on the label itself after removal. They do not heavily contaminate the applied surface.

They are suitable for:

Premium packaging
Gift boxes
Luxury product packaging
Surfaces that should not have strong adhesive residue
Products where appearance after removal is important

This structure is often used for brands that need security protection without an overly industrial look.

Custom VOID Pattern Labels

Custom VOID pattern labels can show special messages after removal. Instead of a standard VOID pattern, customers can customize the security effect.

Common custom options include:

VOID
OPENED
STOP
Company logo
Custom warning message
Serial number
QR code
Barcode

For brands that need stronger identification and traceability, custom void stickers can combine security messages with variable data printing.

For example, an electronics brand may place a VOID label over the screw area of each device. If a distributor or end user opens the device without authorization, the label will display a VOID message. The after-sales team can then quickly determine whether the product has been opened or tampered with.

6. Custom Options for Red VOID Labels

Many customers need labels that match their brand, product size, and application environment. That is why customization is important.

Available custom options include:

Label size
Label shape
Red color shade
Surface finish
Logo printing
Warning text
Serial number
Barcode
QR code
VOID message
OPENED message
Roll format
Sheet format
Adhesive type
Transfer effect
Indoor or outdoor material

Red VOID labels can be supplied in rolls for easy manual application or automated labeling.

For customers who need brand-specific protection, custom void stickers can include company logos, serial numbers, QR codes, and special warning messages. This helps combine tamper evidence with product tracking and brand authentication.

7. How to Choose the Right VOID Label for Your Packaging

Choosing the right VOID label depends on the actual application. A label that works well on a paper box may not work the same way on PE plastic, PP plastic, glass, or metal.

Before choosing tamper evident void labels, consider the following factors.

Surface Material

Different surfaces require different adhesives.

Common surfaces include:

Paper carton
Plastic
Metal
Glass
Painted surface
PE
PP
PET
PVC
ABS

Low-surface-energy plastics such as PE and PP may need stronger adhesive and sample testing.

Application Environment

The environment can affect adhesive performance.

You should consider:

Indoor use
Outdoor use
High temperature
Low temperature
Humidity
Dust
Sunlight exposure
Transportation conditions

For outdoor applications, weather-resistant material and adhesive should be selected.

Tamper-Evident Effect

Different projects need different security effects.

You can choose:

Full transfer
Partial transfer
Non-transfer
Custom VOID pattern

If strong visible evidence is required, full transfer may be better. If the product surface should remain cleaner, non-transfer may be more suitable.

Customization Needs

Some customers only need a simple warning label. Others need product tracking.

Customization may include:

Logo
Serial number
QR code
Barcode
Warning message
Product code
Batch number

Label Size

Small labels are suitable for electronics, screws, and warranty seals.

Long strip labels are suitable for box sealing, envelope sealing, and package closure.

Larger labels are suitable for cartons, logistics parcels, and high-value product packaging.

8. Red VOID Labels vs Regular Stickers

Regular stickers can be removed without leaving clear evidence. In many cases, they can be peeled off and reapplied, especially if the adhesive is weak or the surface is smooth.

red VOID security labels vs Regular Stickers

VOID labels are different. They are designed to reveal tampering.

Item	Regular Stickers	VOID Security Labels
Tamper evidence	Usually no	Yes
Reuse after removal	Sometimes possible	Usually not possible
Security message	No hidden message	VOID, OPENED, or custom message
Anti-return protection	Weak	Stronger
Packaging security	Basic decoration or information	Security protection
Custom serial number / QR code	Optional	Commonly used

This is why void if opened labels are more suitable for product security, warranty protection, and anti-tamper packaging than regular stickers.
