CAMERA PHONE SECURITY LABELS – BLOCKER STICKER – PHONE CAMERA SEAL

Security camera privacy labels are applied to phone camera lenses to prevent sensitive data from being photographed or to laptop ports to prevent network access or even placed on doors to monitor whether the door has been opened. They can also be used for other applications requiring privacy. Completely removing, partially removing, or even peeling back the edges of the label creates a visual indicator that makes it easy for your security team to identify quickly.

Removable Mobile Phone Camera Tamper Evident Stickers

How do camera and computer tamper-evident stickers work?

When anyone attempts to peel off the sticker (i.e., removing all or part of it or even peeling the edges of the sticker), our sticker will begin to display the VOID OPEN symbol as an indicator, helping the company’s security personnel quickly identify it.

Our security label’s key features: Our mobile camera security labels are coated with a removable, residue-free adhesive, so the label adhesive can be easily removed without leaving marks on your guests’ mobile phones. Our mobile phone camera security stickers help your company fully achieve its goal of protecting trade secrets and business operations. It is very useful in today’s era, when data and technology play an important role for any business.

At the same time, your guests will leave with their expensive smartphones without any adhesive residue. In addition to the above, the Security team of every company at the guest entrance has a huge responsibility to collect mobile phones from Guests and provide them with tokens. This requires more space at the security area, additional working time, the possibility of confusion when exchanging mobile phones, etc. The performance of our labels eliminates these activities and saves the organization a significant amount of time.

What is the structure of a void open label like?

The “Void Open” (Void) label consists of three main layers: the top coating/film, the patterned adhesive layer, and the protective liner, designed to leave a visible message (e.g., “VOID” or “OPEN”) when peeled off, indicating that tampering has occurred. This structure is typically made from durable materials such as polyester or vinyl.

Structure of the VOID label:

Top layer (Surface material): A flexible film (usually polyester) that is resistant to moisture and environmental damage.
Adhesive layer (“Void” pattern): A specialized adhesive (acrylic) that serves as the primary anti-counterfeiting mechanism. It contains a “VOID” message that is printed, hidden, or chemically treated, which is only revealed when the label is lifted.
Protective liner: A layer of paper or plastic that protects the adhesive until application.

Types of transfer constructions:

Full transfer: The entire “Void” message remains on the surface, removing the printed ink from the label. No residue (No residue left behind): The message appears on the label, but leaves no adhesive residue on the packaging.
Partial transfer: The message is separated, leaving residue on both the surface and the label.

These labels typically use colors such as red, blue, or yellow for easy visibility and can be customized with a logo or barcode for inventory tracking.

VOID open label production process

The production of VOID open labels involves creating multilayer tamper-evident labels that display hidden messages (e.g., “VOID,” “OPENED”) when peeled off, using specialized materials such as tearable PET or vinyl. The main steps include printing security patterns, applying strong adhesive, and precision die-cutting, ensuring permanent evidence of tampering.

Key stages of the production process:

Substrate selection: Durable materials such as polyester (PET), vinyl or tearable films are selected to ensure the label tears or displays signs of tampering.
Printing: Specialized printing techniques embed hidden messages, logos or serial numbers. This may include digital or offset printing.
Adhesive application: A high-tack, pressure-sensitive adhesive is coated onto the film, typically customized for specific surfaces (plastic, metal or paper).
VOID layer application: A release coating or specialized “void-forming” layer is applied, ensuring the hidden message separates from the film and remains on the substrate surface when the label is peeled off.
Die cutting & finishing: The labels are die-cut to size. Security cuts may be added to ensure the label breaks into multiple pieces when peeled off.
Quality inspection: Finished labels undergo tests for adhesion strength, heat resistance and the clarity of the anti-counterfeiting message.

Void open sticker sizes

Residue-free adhesive labels, used to cover phone cameras, available in various sizes, from small, targeted labels (10x10mm) to larger, comprehensive coverage labels (40x25mm, 40x70mm, 90x40mm). These stickers are designed to securely cover both front and rear cameras and will display a “VOID” message if removed.

Common Void label sizes for cameras:

Small/Individual lens cover: 10x10mm, 10x20mm, 20x20mm
Medium/Large camera module: 40x25mm, 40x70mm, 20x40mm
Extra large/Full coverage: 90x40mm, 50x50mm

Types of VOID OPEN TEM

Full transfer: Leaves all adhesive and VOID pattern on the surface.
No transfer: Leaves no residue on the surface, useful for, for example, high-end electronic devices.
Dual/triple VOID: Technology that displays 2 or 3 colors when opened to enhance security.

These labels are essential for ensuring product safety in the pharmaceutical, electronics, and logistics industries.

How to use CAMERA STICKER – VOID OPEN STICKER

Tamper-evident seals (tamper-proof labels) are used to protect products by displaying a “VOID” or “OPEN” message if removed. To apply, make sure the surface is clean, dry, and smooth, then press firmly and evenly to ensure strong adhesion. They are best used on flat, hard surfaces such as electronic devices, packaging, or documents.

Steps for using tamper-evident security labels:

Prepare the surface: Clean the surface to remove oil, dust, or moisture to ensure good adhesive bonding.
Apply securely: Peel the label from the liner and press it firmly onto the surface, smoothing it out to remove air bubbles.
Avoid excessive bending: Polyester labels have high “memory” and may “spring” up if applied over sharp edges; use larger labels for curved surfaces.
Check for tampering: After application, any attempt to remove the label will leave a visible “VOID” or “OPEN” message, often leaving residue on the surface (or inside the label itself).

Methods for storing void-open camera stickers

To store labels printed with the word “VOID” (open), keep them in a dry, cool, well-ventilated place (at an appropriate temperature) in a sealed plastic bag to protect them from moisture, light, and contaminants. Make sure to apply the labels to a clean, dry surface with even and firm pressure, avoiding areas that are frequently touched to maintain the integrity of the security message.

Key storage techniques and main applications:

Optimal storage conditions: Avoid exposing the labels directly to sunlight, high temperatures, and chemical contamination. The ideal storage conditions are at a suitable temperature, with a relative humidity of 55%.
Surface preparation: Apply the label to a clean, dry, and flat surface, free of grease or dirt to ensure good adhesion.
Application pressure: Apply even and firm pressure over the entire label during application to ensure the “VOID” adhesive bonds properly.
Environmental protection: If used in harsh conditions, consider adding a transparent protective film or UV coating to prevent fading and damage.
Handling: Avoid touching the adhesive side to maintain the integrity of the security message.

If stored properly in a dry, cool, and well-ventilated place, these labels typically have a shelf life of about one year.
