VOID LABELS

The Void Stickers, provide excellent prevention against counterfeit, theft and duplicity. ...

The stickers have hidden text and images on the adhesive surface, which leaves an impression on the pasted product in case of tampering to avoid duplicity and theft.

Security tape (or security label) is a type of adhesive tape used to help reduce shipping losses due to pilfering and theft. It helps reduce tampering or product adulteration. Often it is a pressure sensitive tape or label with special tamper resistant or tamper evident features. It can be used as a ‘’security seal’’ in addition to a container closure or can be used as a security label. They are sometimes used as or with authentication products and can be an anti-pilferage seal.

Security tapes can be used as packaging tapes on small primary packages such as bottles and cartons or on larger shipping containers such as corrugated boxes. They are also used on unit loads or palletized goods. The strength and adhesive bonding are important. Security labels are usually only used for their security features; backing strength is less important but the bonding characteristics are critical. Some security tapes have an appearance similar to standard packaging tapes to help conceal the value of an item. Logistics and packaging professionals do not want to bring attention to the item or its package.[1] Other security tapes have bright colors with high impact graphics.

The Void Labels is 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.

Most void labels use a void message that simply says "Void".
