There are two types of void label which both offer unique advantages for specific applications, ensuring use case flexibility, whilst still providing a high level of tamper evident security. Versapak offer two types of tamper evident labels in a variety of sizes which can all be customised to your exact requirements. These two types are as follows:
- Residue Void Labels
- Non-Residue Void Labels
Residue Void Labels
Residue void labels (KN) are a popular tamper evident solution designed to leave a clear, visible indication when an item or packaging has been tampered with. These labels work by transferring an adhesive message, such as "VOID" & "OPEN," onto the application surface when the label is removed. The residue left behind is designed to be resistant to cleaning or removal, ensuring the void message is permanently visible.
This permanent mark signals interference, deterring unauthorised access and ensuring the integrity of the product or package. Commonly used in packaging, cardboard boxes, pharmaceutical products, food delivery bags, ATM cassettes, and industrial machinery.
Non-Residue Void Labels
Non-residue void labels (KNR) are also a tamper evident solution that ensures security but without leaving any adhesive residue behind. When removed, these labels reveal a clear tamper message, such as "VOID" & “OPEN” directly on the label surface, while the application surface remains clean and undamaged due to the adhesive’s unique formulation. Attempting to reapply the label will fail, as the message remains visible, and the adhesive’s original strength is lost.
This makes them ideal for applications where maintaining a pristine surface is crucial, such as electronics, glass, aircraft catering trolleys, sensitive documents, vehicles, reusable containers, artwork and exhibits. Non-residue void labels offer robust tamper protection while preserving the appearance and usability of the sealed item, making them a discreet yet effective.
Choosing the Right Void Labels for Your Security Needs
Residue and non-residue void labels offer effective tamper evident solutions tailored to different applications. Whether you need permanent evidence of tampering with residue void labels or a clean, damage-free option with non-residue void labels, both provide reliable protection against unauthorised access.
