VOID Labels
Clear, Irreversible Tamper Evidence

How VOID Labels Work

VOID labels provide a clear and immediate indication of tampering. When someone attempts to lift the label, a hidden VOID message is revealed—either left behind on the surface (transfer VOID) or exposed within the label itself (non-transfer VOID). In both cases, the seal cannot be replaced without visible evidence of interference.

The polyester construction offers excellent dimensional stability, resistance to solvents, and reliable adhesion on smooth surfaces such as metal, plastics and painted substrates. VOID labels are a preferred solution when you need to protect products, packaging and equipment without damaging the underlying surface.

Common Applications:

• Product packaging and retail sealing
• Secure documents and envelopes
• Warranty validation and returns control
• Access panels, electronics and service points

Unsure whether transfer or non-transfer VOID is best for your application? We can help specify the right construction.

Polyester VOID Labels for Clean, Reliable Tamper Evidence

VOID labels are engineered using dimensionally stable polyester films designed to provide predictable and irreversible tamper evidence. These constructions maintain clarity, resist stretching, and deliver consistent message activation when removed.

All VOID materials are compatible with thermal transfer printing for barcodes, serial numbers and branding. If you're unsure which structure is correct, we can help specify the right face stock and adhesive.

Where VOID Labels Deliver the Best Protection

VOID labels provide clean, highly visible tamper evidence without damaging the underlying surface. This makes them ideal for product sealing, authentication, warranty protection and secure access points — anywhere a clear visual alert is required when interference occurs.

Common Applications:

• Product and retail packaging seals
• Warranty protection for electronics and equipment
• Secure documents, envelopes and confidential files
• Returns validation and fraud prevention
• Access panels, service points and inspection covers
• Authentication labels for branded goods

Whether you're sealing cartons or protecting sensitive components, we can manufacture VOID labels to your required size, message pattern and adhesive strength.

Tailored VOID Labels for Products, Packaging & Equipment

VOID labels can be manufactured in a wide range of sizes, shapes and constructions to meet your process needs. Whether you require discrete warranty dots, large-format seals for cartons, or branded security labels, we can produce a specification that fits seamlessly into your workflow.

• Custom sizes and label shapes
• Choice of message patterns (VOID, checkerboard, custom text)
• Surface-transfer or non-transfer constructions
• Permanent and high-tack adhesive systems
• White and silver polyester films
• Compatible with thermal transfer overprinting

Looking for branded or part-printed options? Our custom label service supports logos, serial numbers, barcodes and instructional artwork for enhanced authentication and traceability.

VOID vs Destructible Vinyl — Which Do You Need?

VOID and destructible vinyl labels both provide tamper evidence, but they behave differently and are suited to different workflows. Understanding their strengths helps ensure you choose the right solution for your process.

• VOID Labels — Reveal a clear VOID message when lifted. Ideal when you want visible tamper evidence without damaging the product. Best for packaging, electronics, returns and document protection.
• Destructible Vinyl Labels — Fracture into small pieces on removal, making clean lifting very difficult. Best for warranty seals, asset protection and applications where the label must not come off intact under any circumstance.
