This type of label works by depositing some of its colour onto the product in the form of the standard word ‘void’, a custom text (e.g. ‘opened’) or a logo. Therefore, when the label is removed, it leaves a visual indication of attempted tampering. If the message or logo is erased from the product, then the same alert message will still show up in negative when the label is re-affixed.

Description
The distinctive feature of void labels is that the alert message or logo remains invisible until the label is removed. Once the adhesive film has been removed from the surface of the object, the label’s integrity cannot be restored and any tampering will be evident.
Uses
These labels may be applied to goods sold under warranty, leased goods and goods undergoing servicing or repair in order to show evidence of unauthorised interference. They also provide an effective way to control and monitor product integrity along the entire supply chain, from manufacturing to retail sales.
Implementation
Implementing this technology will require changes to be made to the stage in the production process at which labels are attached to the product or packaging. As with other types of labels, partly or fully automated solutions are available for those void labels that do not need to be applied manually, depending on the quantity to be applied.
Cost
The costs associated with void labels are fairly low, but will vary according to customisation.
