Security labels are used to indicate whether a product, device, or component has been opened, removed, or altered. They help protect against unauthorized access, relabeling, or substitution and serve as a visible warning of tampering attempts.
Becher manufactures security labels for various requirements – depending on the application, as a VOID solution or as a destructible document film. The appropriate version depends on the substrate, operating environment, and desired security effect.![]()

Not every security label is suitable for every substrate or application. Depending on the use, different label systems may be appropriate, such as VOID effect labels or destructible document films.
The most suitable solution depends, among other factors, on the surface, adhesion, desired visibility of the tamper indication, and labeling requirements.

Depending on the label type, any removal attempt becomes immediately apparent – either through a visible pattern or by destruction of the material.
VOID labels and destructible document films are suitable for different applications and substrates, allowing the appropriate solution to be chosen for each use case.
Serial numbers, barcodes, DataMatrix codes, or variable content can be integrated directly into the label.
Content, sizes, shapes, colors, and instructions can be adapted to the product, equipment, or process.
Depending on the material and construction, security labels can be designed for various environments and levels of stress.

A destructible document film is suitable when the label should break or tear upon removal. A VOID film is appropriate when a tampering attempt should be immediately visible through a pattern or message. The choice depends on the product, substrate, and desired effect.
Yes, security labels are often used as warranty or closure seals. They make it visible if a housing, cover, or sealed area has been opened or tampered with. The legal significance in each case depends on the specific application and the relevant conditions.
The final adhesion develops over a certain period, depending on the material, adhesive, and substrate. For many applications, it is therefore important that the label is given sufficient time to achieve full adhesion after application.
Yes, at Becher Security labels can be equipped with barcodes, DataMatrix codes, sequential numbering, or other variable data. This allows a visible tamper indication to be combined with additional identification.
Yes, content, colors, symbols, sizes, and shapes can generally be customized. However, not every design is technically feasible for security labels: for destructible document films, for example, full-surface or heavily negative printed designs can affect the destruction effect, as the ink may hold the film together. Therefore, we always evaluate design and security effect together.
Yes. Depending on the application, we can integrate, for example:
This allows security labels to be used for traceable internal processes or product-specific identification.
Yes. Becher Industrieschilder produces security labels in both small quantities and large series, depending on the application and desired version.
