Tamper-Evident Security Solutions for Packaging Protection

KURZ SCRIBOS tamper-evident solutions to protect packaging, detect tampering, and secure supply chains

Unauthorized opening, theft, and product substitution are increasing risks across production, transport, and distribution. Without clear visibility, compromised packaging can lead to product loss, contamination, and reduced product integrity before goods reach customers.

KURZ SCRIBOS tamper-evident security seals detect packaging interference through clear, irreversible VOID indications when opened. Combining advanced materials and high-performance adhesives, these solutions protect cartons, transport packaging, and products, while integrating seamlessly into existing packaging and logistics processes across industries.

Challenges tamper-evident seals solve

When products move through complex logistics and distribution networks, companies face several risks:

Packages opened during transport or storage
Theft or product substitution within logistics environments
Unauthorized access before products reach customers
Manipulation or refilling of packaged goods
Limited visibility when packaging integrity has been compromised

Security seals make these incidents immediately detectable by providing clear visual evidence when packaging has been opened or manipulated.

Key Benefits of Tamper-Evident Security Seals

Security seals protect packaging integrity while remaining easy to apply and verify throughout the supply chain.

Key advantages include:

Clear visual indication when packaging has been opened
Customizable VOID messages for brand-specific security
Compatibility with automated packaging processes
High-performance adhesives optimized for a wide range of packaging surfaces, ensuring reliable performance across different materials

These capabilities make tamper-evident packaging seals an effective solution for protecting products across logistics and distribution environments.

Why Tamper-Evident Seals are Different from Standard Packaging Seals

Conventional packaging seals, tapes or adhesive closures cannot reliably reveal whether a package has already been opened. After resealing, manipulation often remains undetected.

Tamper-evident security seals use specialized multi-layer constructions that create a visible VOID message when removed. This irreversible indication remains on the packaging surface even if someone attempts to reseal the package.

Because this tamper indication cannot be removed or concealed, security seals provide reliable protection against unauthorized opening, theft, and product substitution.

When Tamper-Evident Security Seals are the Right Solution

Security seals are particularly suitable when packaging integrity must remain visible and verifiable throughout transport and distribution. Typical situations include:

Products vulnerable to theft or substitution
Goods such as wine & spirits or cigarettes that may be opened, refilled or replaced during transport or distribution

Quality-sensitive products
Products where consumers must be confident that packaging has not been opened before purchase. This is especially critical for categories such as infant nutrition, pharmaceuticals or medical products

Transport and logistics packaging
Cartons or shipping units that must remain sealed until they reach their destination

Complex logistics networks
Distribution environments where goods pass through multiple handling points before reaching the end customer

Tamper-Evident Sealing Solutions from the KURZ SCRIBOS Brand

The KURZ SCRIBOS brand offers tamper-evident sealing solutions for different packaging environments, security requirements, design needs and sustainability goals. The portfolio includes the HighPerSeal^® family for visible first-opening indication, as well as HiddenCode, a separate tamper-evident label concept for secure consumer engagement after opening.

HighPerSeal^® Family

HighPerSeal^® security seals protect packaging against theft, tampering and product substitution. When removed, the seal leaves a clearly visible VOID message or security pattern on the packaging surface, providing irreversible proof of first opening.

Key capabilities include:

First-opening indication: When the HighPerSeal^® label is removed, a clearly visible VOID effect remains on the packaging surface.
Permanent warning: The VOID effect remains clearly visible even if an attempt is made to reseal the label.
Strong adhesion: A high-performance adhesive system ensures excellent adhesion and tamper resistance on a wide range of surfaces.
Customizable VOID effect and design: The VOID effect can include graphic elements and text such as “OPENED” in multiple languages. The label can also be customized in size, shape and design to fit packaging and brand requirements.
UV security feature: The VOID effect is visible under UV light, even without opening the label.

HighPerSeal^® is widely used to protect product packaging, transport cartons, and logistics shipments.

HighPerSeal^® Variants

HighPerSeal^® Standard

The proven solution for reliable tamper-evident sealing across a wide range of packaging applications.

HighPerSeal^® Transparent

Provides visible opening indication without covering packaging information and works on both light- and dark-colored packaging.

HighPerSeal^® with 3-Color VOID

A three-color VOID effect makes first-opening evidence more eye-catching, easier to recognize and more difficult to imitate.

HighPerSeal^® Green

A sustainability-focused variant using environmentally friendly materials while offering the same application performance and opening indication as polymer film.

Additional options for HighPerSeal^®

Depending on the selected HighPerSeal^® variant, additional elements can be integrated to support brand design, authentication or track-and-trace applications.

Design and decoration

Custom colors, layouts, shapes, VOID messages or decorative effects such as cold foil or gold elements can support brand differentiation and shelf appeal.

Barcode or QR code integration

Barcode or QR code elements can support authentication, customer interaction or track-and-trace applications.

HiddenCode

HiddenCode is a tamper-evident label concept with an integrated promotion code that remains hidden until the product is opened. The code is concealed from counterfeiters, scammers and unauthorized users before purchase.

When the label is removed, the code becomes visible to the buyer. This enables brands to offer promotions, rewards or exclusive content while ensuring that access is linked to an actual product purchase.

Key capabilities:

Integrated promotion code concealed until first opening
Protection against early code exposure, copying and fraudulent use
Access to incentives, rewards or exclusive content for actual product buyers
Combination of tamper evidence and controlled code release in one label concept

HiddenCode is suitable for applications where promotional value must be protected until the product reaches the legitimate customer.

Choosing the Right Tamper-Evident Sealing Solution

The right security seal depends on the packaging material, logistics environment and the level of tamper visibility required.

Effective packaging protection requires more than simply applying a seal. The design of the VOID indication, adhesive performance and material structure must be aligned with packaging type, logistics conditions and risk scenarios.

The KURZ SCRIBOS brand develops tamper-evident sealing solutions based on extensive experience in packaging security and anti-counterfeiting technologies. This ensures that security seals deliver reliable tamper detection under real-world logistics and distribution conditions.

KURZ SCRIBOS experts support companies from risk assessment and solution design through implementation and global rollout, ensuring seamless integration into existing packaging and logistics processes.
