Tamper-Evident Release Films
Permanent-transfer tamper evidence that leaves a visible VOID residue on the substrate when removal is attempted.

Standard VOID material is a transfer construction: when the label or film is lifted from the surface it was applied to, part of it stays behind. What remains is a tacky VOID residue that marks the substrate permanently.
It is suited to coated paperboard, glass, plastic and metal — surfaces smooth enough for the residue to transfer cleanly and stay legible. Applications include pharmaceutical packaging, aviation and consumer-goods packaging where a seal needs to prove whether it has been opened.
Where the substrate is corrugated or uncoated paper, the dry-peel construction is usually the correct choice instead, because residue transfer behaves differently on porous surfaces.
A tacky VOID residue remains on the substrate after removal and cannot simply be wiped back to an unopened state.
Suitable for coated paperboard, glass, plastic and metal.
Used in pharmaceutical packaging, aviation and consumer-goods applications where evidence of opening matters.
Supplied as film and label material that runs through conventional label converting.
01
The label or film is applied to coated board, glass, plastic or metal.
02
Someone attempts to lift the seal.
03
The construction separates and part of it stays bonded to the substrate.
04
A tacky VOID residue is left on the substrate, marking it permanently.
