Security label materials for reliable converting in tamper-evident and authentication applications

Security labels are a functional part of product safety and protection. From pharmaceutical packaging and electronics to food and cosmetics, security label constructions must protect products by making tampering visible, support authentication and maintain reliable performance across printing, converting and dispensing.

Our security and brand protection label materials protect products throughout the supply chain without compromising operational efficiency. This means label materials that run reliably, convert efficiently and adhere securely, even on complex packaging substrates – ensuring durable tamper evidence and authentication across regulated and high-value packaging applications.

Built for the realities of security label converting and dispensing

Consistent adhesion and tamper evidence without adhesive residue

Security labels often need to bond to glass, coated cartons, metallized films and flexible plastics without lifting or edge flagging. Security labels such as VOID and delamination constructions are designed to support residue-free tamper evidence without compromising packaging appearance.

Stable converting and dispensing on automated packaging lines

VOID, destructible and holographic constructions require stable die-cutting, matrix stripping and dispensing performance. Our constructions are engineered to support efficient converting and reliable high-speed application with optimized label stiffness and construction thickness.

Full material traceability and compliance support for regulated applications

Pharmaceutical and other regulated security label constructions require full material traceability and documented compliance with applicable standards.

Our label materials are supported by technical documentation and traceability information to satisfy customer audits and regulatory submissions.

Tamper-evident label solutions to reveal product interference

VOID labels

VOID label constructions reveal a pattern or text when the label is partially or fully removed, making tampering immediately visible.

Our standard VOID labels leave a sticky residue, while our No Tack VOID label solutions are designed for residue-free removal on premium packaging such as high-gloss films, glass and lacquered metal surfaces.

Watch the video to see how the VOID labels work.

Delamination labels

Delamination seal labels delaminate or tear irreversibly when opened or removed, making tampering visible and preventing reapplication.

Designed for applications such as pharmaceutical closures, food-safety seals and other security-sensitive applications, our delamination labels can also incorporate additional security features such as holograms, QR codes and serial numbers.

Watch the video to see how the delamination labels work.

Ultra-destructible labels

The facestock of destructible and ultra-destructible safety seals fragments during peel attempts, making label transfer or reapplication impossible.

Suitable for asset tracking and high-security tamper-evident applications, these constructions can be combined with additional security and authentication features such as holograms, QR codes or serial numbers.

Authentication labels for product verification

Holographic labels

Holographic authentication labels use a metallized optical layer that cannot be reproduced on standard print equipment. The labels contain “Original” or “Security” text as a visible authentication feature.

The constructions are compatible with conventional and digital printing technologies, including variable information and serialization applications.

Security fiber paper labels

Security fiber paper labels deliver covert brand authentication through visible and UV-visible fibers with chemical sensitization embedded directly in the paper substrate. Invisible under normal light and readable only with a UV detection device, these labels increase resistance to reproduction compared with surface-applied security elements.

Shadow print and taggant labels

Shadow print and taggant labels offer overt and covert authentication through printed or embedded security features that confirm product origin and deter reproduction.

The label solutions are suitable for regulated and premium applications, such as pharmaceuticals and premium FMCG.
