Security sticker

Security stickers: make tampering visible – with VOID film or destructible paper

Security stickers are a fast and effective way to make tampering attempts clearly visible. They show at a glance whether packaging, a product or a device has been opened, removed or altered. Depending on the material, this is achieved either through a VOID reveal effect on film or through destructible paper that breaks apart when removal is attempted. This helps protect your goods, your brand and your processes, from dispatch and fulfilment through to warranty labelling.

Whether used as a tamper-evident label, warranty seal, inspection label or closure sticker, security stickers work best when the material and surface are properly matched. That is why three proven security materials are available here: two film options and one paper-based material.

Typical applications for security stickers

Security stickers are useful wherever it must be clear that an item is “unopened” or “unaltered”, for example:

The advantage: evidence of tampering is created directly by the label itself, without the need for any additional sealing technology.

Three materials for security stickers – briefly explained

1) VOID PET film (white or transparent) – robust, weatherproof, strong adhesion

This security film is designed for demanding applications. When removal is attempted, a clearly visible VOID message is left behind. At the same time, the material offers high tensile strength and stretchability, which is useful when surfaces are slightly flexible or when the label is exposed to mechanical stress.

Suitability & properties (based on your material selection):

Typical applications: dispatch labels, outdoor labelling, containers and packaging exposed to changing conditions.

2) VOID PET film with hologram – security performance with an anti-counterfeit look

This option combines the VOID tamper-evident effect with a holographic security appearance. It is ideal when security stickers should not only reveal tampering, but also visibly support product authenticity. In use, the material performs as reliably as standard VOID PET film, with the added benefit of a visual authentication effect.

Suitability & properties (based on your material selection):

Typical applications: warranty seals, high-value branded products, authentication or inspection processes, retail and reseller structures.

3) Security label made from paper – opaque, tamper-resistant, destructible

This paper-based material is the classic solution for indoor applications where clean removal must be deliberately prevented. Instead, the label breaks apart when removal is attempted, making tampering immediately visible. Thanks to its high opacity, it is also well suited to applications where the surface underneath should not show through.

Suitability & properties (based on your material selection):

Typical applications: folding boxes, sets, retail product packaging and simple first-opening protection.
