WHAT IS A TAMPER-EVIDENT SEAL?
A tamper-evident seal is a security label designed to provide visible evidence when a package, product, or container has been opened, manipulated, or removed.
Unlike ordinary labels, tamper-evident seals leave a visible indication of opening, such as:
- VOID messages
- Destructible materials
- Residue patterns
- Cut indicators
- Kiss cuts
WHY USE SECURIKETT TAMPER-EVIDENT SEALS?
The real challenge is not applying a tamper-evident seal. It is ensuring that the seal cannot be removed, transferred or manipulated throughout the product’s entire lifecycle while remaining easy for consumers to verify. Our technological diversity makes us experts in customized VOID solutions.
Benefits for Brands
- Protection Against Tampering with Packaging: Damage or alterations to the packaging are visible and cannot go unnoticed.
- Protection Against Unauthorized Opening: The label clearly indicates whether a package has been opened prior to purchase or its intended use.
- Protection against unauthorized refilling: Tamper-evident solutions make it difficult to refill original packaging with foreign, inferior, or potentially hazardous contents.
- Protection against substitution with counterfeits: The labels help prevent original products from being removed unnoticed and replaced with counterfeit or unauthorized products.
- Protection against Re-sealing: Once opened, packaging cannot be easily resealed without leaving visible signs of tampering.
- Protection of Brand Reputation: Visible security features reduce the risk that tampered with, swapped, or counterfeit products will be associated with the brand.
- Greater Trust and Differentiation: Tamper-evident labels signal quality, a sense of responsibility, and high standards for product and consumer safety.
- Support for Counterfeit Protection: Additional security features such as VOID technologies, holograms, cold-stamped foils, UIDs, and serialization enhance protection and facilitate the identification of genuine products.
Benefits for Consumers
Visible Original Condition: It is immediately apparent whether a package has already been opened or damaged.
Protection against tampered products: Unauthorized opening, refilling, or resealing leaves visible traces.
Reduced health and safety risks: Tampering can be detected early, particularly with pharmaceuticals, cosmetics, food, or other sensitive products.
Better protection against counterfeits: Security features make it more difficult to replace an original product with a counterfeit or inferior product.
Greater confidence when making purchasing decisions: Consumers can better assess whether a product is intact and trustworthy.
Increased trust in the brand: Visible tamper-evident protection demonstrates that a brand takes product quality and consumer safety seriously.

Greater transparency and traceability: When combined with smart labels, additional product information, origin data, or proof of authenticity can be accessed.
COUNTERFEIT PRODUCTS ARE A GLOBAL PROBLEM WORTH BILLIONS
According to the joint report “Mapping Global Trade in Fakes 2025” by the OECD and EUIPO, global trade in counterfeit and pirated goods reached an estimated value of $467 billion in 2021. This represents up to 2.3% of global trade; for imports into the European Union, the share was as high as 4.7%.

WHICH VOID TECHNOLOGY IS RIGHT FOR YOUR INDUSTRY?
Tamper evident seals are designed to ensure that different types of tampering attempts are clearly detected and indicated. Depending on the application, specific securitymechanisms are employed.
The most suitable VOID technology depends on the level of protection you want to achieve. Here, we’ll just give you a brief overview of which technologies might be appropriate. In many cases, a good mix of technologies provides the ideal protection against tampering.
A standard VOID solution may be sufficient for simple tamper detection.
Yes. Our patented Paper-VOID was developed specifically for paper and cardboard packaging. It adheres reliably to fiber-based surfaces and makes any attempts to open or tamper with the package clearly visible.
To prevent a VOID label from being cut through unnoticed, an additional Cut Indicator protection feature provides even greater security.
For high-quality products and luxury items, a residue-free solution is often required. A traceless VOID is ideal for this purpose, as it leaves no residue on the product and self-destructs when removed, preventing it from being reapplied.
Additional security and finishing elements, such as holograms or cold-stamping foils, can further enhance protection against counterfeiting while also underscoring the brand’s exclusivity and perceived value.
If the label is to be equipped with a unique identification number—a so-called UID—we also offer the appropriate serialization solution. For more information, please see the Smart Labels section.
Temperature-sensitive inks can be integrated directly into the label. If the temperature exceeds or falls below defined thresholds, they change their optical properties and make the thermal stress visible.
Our WashVOID technology reacts to contact with water or other liquids by causing a visible change in the label. This makes it possible to reliably detect even non-mechanical attempts at tampering.
With Triple VOID, as the label is peeled off layer by layer, multiple VOID layers in different, surprising colors become visible. This transforms the tamper-evident feature into a unique brand experience and creates an added element of surprise for customers.
A transparent or translucent VOID seal protects the packaging without obscuring the design, colors, or product information. When the package is sealed, the label remains discreet, while any attempt to open or tamper with it becomes clearly visible.
A resealable VOID seal is ideal for products that are consumed in multiple stages. When the package is opened for the first time, the VOID effect is permanently triggered, clearly indicating that the package has already been opened. However, the label remains functional afterward and can still be used to reseal the package multiple times—for example, for tea, coffee, or other products that are taken out repeatedly.

DO TAMPER-EVIDENT SEALS WORK ON ALL SURFACES?
Whether a closure seal adheres reliably depends on the material, the surface structure, and any coatings on the packaging. A suitable adhesive system can be selected for most applications. Since we develop our own materials and combine them individually, we can tailor our solutions specifically to the respective packaging surface.
However, adhesion may be limited on highly textured, silicone-containing, or PTFE-coated surfaces. That is why we offer application tests directly on your original packaging. This allows us to select the appropriate adhesive and ensure that the closure seal functions reliably.
WHAT MAKES OUR TAMPER-EVIDENT SECURITY SEALS SO SPECIAL?
SIMPLE AND INTUITIVE UNPACKAGING
Our tamper-evident seals are designed for clarity and simplicity. The unexpected opening effect will pleasantly surprise your consumers. For easy opening, we provide convenient opening tabs.
Securikett’s VOID security seals can simply be added even to existing packaging, without any need to change its design to accommodate for the seal. Eye-catching and unambiguous proof of first opening raises consumers trust in products and brands.
Consequently, they are commonly used as security seals to prevent fraud, theft, or unauthorized refilling.
Arrows, symbols, texts, or colored areas clearly indicate where seals should be peeled off.
CUSTOM-DESIGNED OPENING EFFECTS
We implement individual VOID effects into our security seals that fit your brand and design. Whether you want to integrate your logo, symbols, or text into the opening effect – with Securikett there are no limits.
TRANSPARENT SECURITY
Utilizing our translucent or transparent technologies ensures that all information remains legible and undisturbed, even when completely covered by the security seal.
SUSTAINABLE PACKAGING
Our paper-based security seals provide a perfect substitution for plastics. By sealing paper or cardboard boxes with paper-based seals the packaging could be recycled together with the seal.
WHICH LABEL MATERIAL IS SUITABLE FOR WHICH TYPE OF PACKAGING?
There is a suitable label material available for nearly every type of packaging. The key factors are the packaging material, the surface texture, any coatings, the shape of the packaging, and the desired function of the label.
Custom-tailored materials and adhesives
For most applications, a suitable material and adhesive system can be selected. Since we develop our own materials and combine them individually, we can specifically address the properties of each packaging surface.
However, adhesion may be limited on highly textured, silicone-containing, or PTFE-coated surfaces. That’s why we offer application tests directly on your original packaging. This allows us to select the appropriate adhesive and ensure that the closure seal functions reliably.
More Sustainable PP Label Materials
To meet the requirements of the PPWR, we also offer PP label materials containing recycled content. This allows the label material to be better tailored to polypropylene packaging and its recycling requirements.
Partial Adhesive Application
In addition, we have a specialized technology that allows the adhesive to be applied precisely and only to specific areas of the label. Depending on the size, shape, and application, a defined adhesive pattern can offer advantages and optimize material usage. For more information, see the Structure Coating Technology section.
