Tamper-evident labels are a powerful deterrent to theft and relabeling. They are based on destructible and ultra-destructible papers and films that are destroyed when an attempt is made to remove them.
Anti-tamper labels help secure the authenticity of products as they can be printed with identification numbers or other critical information such as warranty numbers and expiry dates. They are also often used as package seals as they are impossible to transfer to other packages.
Destructible label faces
Destructible label papers either have a very low grammage and tear into small pieces when an attempt is made to remove them, or they have a high thickness and weak internal strength, which causes them to delaminate, meaning they split into layers. Destructible film label faces employ the same principles: some thicker films delaminate, while others fragment.
Ultra-destructible face materials
Ultra-destructible label papers are extremely brittle materials that are impossible to remove in one piece once adhered. They make ideal tamper-evident seals for applications such as packaging and warranty sealing, or where highly reliable tamper evidence is required at all stages of the supply chain.
Enhanced security with strong adhesives
Strong adhesives combine with our tamper-resistant face materials to ensure that the tamper seal either tears, flakes, or delaminates if removal is attempted.
Our Tamperproof and Tamperproof Lite face materials both tear if removed. They use adhesives RP51 and RP36.
The label films Acetate White UD, PVC White UD and Acrylate Gloss Clear UD will flake when tampered with. They are best matched with RC18 or RP77 adhesives.
Security White PE and Foamed PS films are paired with RC18, RP77, or RP37S and will delaminate when removed.
We also have a selection of different face materials that work with our RP62 EU adhesive to support legislative requirements for individually authenticated, tamper-evident packs to protect the supply chain from counterfeits in the pharmaceutical industry.
While some of our customers still choose standard security products like voids for pharma applications, the additional features of our RP62 EU products make them the optimal choice to ensure pharmaceutical change management.
