Void Labels - What are void labels?
Definition of VOID LABEL:
A type of security label; these labels are designed to indicate that a label has been tampered with by displaying a void message on the substrate (total transfer), on the back of the label (non-transfer), or both (partial transfer) when the label is removed. This effect is created through special coatings and laminates, depending on the required outcome, which separate or delaminate from the face material as the label is peeled off. These labels are usually made with a polyester face material and an "extra layer", which is either another layer of polyester or a thin coating (usually coloured or metallic). The delamination or separation of this extra layer is controlled by the adhesive and/or a release coating.
In a total transfer, the extra layer has a release coating applied to the side that is laminated to the face material; when the label is removed the extra layer remains attached to the substrate and is usually printed with a void message to indicate tampering has occured.
In a non-transfer, the label can be removed from the substrate but the back of the face material or the extra layer is printed with a void message to indicate tampering has occured.
The most common type of void label is the partial transfer; these are made by applying either a pattern release coating between the face material and the extra layer or a pattern release adhesive. In both cases, part of the extra layer sticks to the face material and part sticks to the adhesive, which causes a void message to appear on both the substrate and the back of the label.
While most void labels use a void message that simply says "Void“, this message can be personalised to suit the end application (for example to display the name or logo of the company who owns or manufactures the item).
At Label Planet, we supply a range of Silver Polyester VOID Labels, which are partial transfer void labels that will leave the message "VOID" on both the item that was labelled and on the label itself.
