Tamper evident labels are designed to show a visible sign of a label being removed or "tampered with". This is achieved with label materials, coatings or mechanical destructs that will partially destruct the label with any attempt to remove. The destruct also prevents the label from being removed, the package opened and the label then reapplied. In addition, a tamper evident label when removed, may also leave a residue on the surface to which it was applied or damage the surface of the container, further indicating that the package has been opened.
Below are a few examples of tamper evident constructions.
Security Slit Labels will destruct if removed, preventing a label from being reapplied to another product or container.
This is the most cost effective method of
producing a tamper evident product since it is typically made using paper labels, that tear into pieces if removed.
These labels are most seen in use for retail pricing and variable data.
Void Pattern Labels when removed, leave a "VOID" pattern of adhesive on the application surface. In addition, the label material itself has a "VOID" pattern created so that the label cannot be reapplied.
Messaging and "void or checker box" pattern are common. Custom messaging is also available.
A Mechanical Destruct Label is a tamper evident label that breaks into small pieces making it unable to be removed cleanly so it cannot be reused or reapplied. This is created by using tooling on the press allowing for any pattern to be cut into the label material so that when the product is removed, the label or a portion of the label will mechanically destruct.
This type of tamper evident label is used most frequently for security, calibration, tax stamp or warranty information and the material is typically vinyl or polyethylene.
ALG has multiple applications utilizing this label feature.
A Wafer Seal, Distortion Label is used to indicate unauthorized access to a box or container. Made out of polystyrene, the label will wrinkle and deform if removed, so that it cannot be reapplied without visible evidence of tampering.
Typically, these are clear polystyrene which allows for an unobstructed view of the package.
This label can include custom text, and a barcode or serial number to allow for easy identification and tracking of assets.
A Wafer Seal, Remove Coating Label is a clear seal that when removed, damages the packaging to which it was applied.
This feature in turn, provides evidence that the product had been tampered with, protecting against unauthorized transfer.
