Void tags: types, usage and applications

Void Labels

Void labels form a part of the security stickers for prevention of external packaging or product tampering. When the label is detached, the adhesive reveals text in which the word “Void” appears, repeated several times. The name of this type of sticker comes from the word “Void”, but other messages such as “Opened” can appear, and they can even be customised.

Types of Void security labels

There are a variety of types of Void labels within the range of security stickers, depending on the material from which they are made and, also, on the amount of residue they leave on the product when they are removed. Let’s take a look at Precintia’s Void labels:

1. Non-residue Void labels

A void label which leaves no residue.The CKNR model Void label has a hidden message which is revealed in the plastic film when the label is removed. Its features include:

  • It is a security sticker that leaves no residue on the surface where it is applied, but the tampering can be seen in the front face of the label.
  • They are manufactured from Mylar polyester and have a high strength adhesive. Both features ensure enormous strength. Not in vain, they resist temperatures of between 0 and 80°C.
  • Their use is recommended on non-porous surfaces.
  • You can write on the surface and they can be customised in shape and size and any kind of logo or message can be added.

Possible applications for non-residue Void labels are as follows:

  • Air, sea and land transport: aircraft doors and windows, containers and air cargo, catering trolleys and storage, vehicle doors, security areas and wooden or plastic pallets.
  • Industry: alarms and security equipment, ballot boxes, emergency equipment, entry/exit doors, panels, extinguishers, first aid kits, computer equipment.
  • Surveillance: communications points and access, valve and pump controls, meters.
  • Financial sector: coin boxes and ATMs.
  • Retail: returns management, packaging protection.

 

2. Void labels with partial residue

  • The CKR Void label model is a type of security sticker that leaves a partial residue on the surface where applied, showing the message that provides evidence of tampering.
  • Application is recommended on non-porous surfaces.
  • They are made from the same material as the previous model – Mylar polyester – and they have high strength adhesive.

Possible applications for Void labels that leave a partial residue are as follows:

  • Air, sea and land transport: containers and air cargo, catering trolleys and storage, security areas and wooden or plastic pallets.
  • Industry: panels.
  • Surveillance: security envelopes and bags.
  • Retail: returns management, packaging protection.

 

3. Void labels that leave a full residue

Void label that leaves a full residue

  • KTL and KTL+ Void label models are designed to be applied to porous surfaces, such as cardboard, paper or fibreboard.
  • When the sticker is removed, these labels leave a hidden message stuck to the surface, identifying the package or product tampering.
  • They are made from translucent polypropylene and also have a high strength adhesive.
  • The big difference between KTL and KTL+ Void labels is the external numbering of the latter type. In both cases, the rest of the identification is present in the plastic film underlayer, hence they cannot be modified.

Possible applications for full residue void labels are as follows:

  • Surveillance: security envelopes and bags.
  • Financial sector: boxes in general, envelopes and confidential mail.

 

Using Void labels lets you protect products against tampering and combat fraud and counterfeiting, as they are difficult to replicate and, finally, they are a way of identifying goods to be able to control traceability.
