What is Tamper Evident VOID Label Materials?

            Tamper evident security material is a functional film or substrate engineered to show visible evidence when someone attempts to remove, open, reseal or manipulate a protected package or product.

            Unlike ordinary adhesive film, tamper evident material is designed with special release layers, security coatings, hidden VOID messages, color-changing inks or optical anti-counterfeit effects. Once tampering occurs, the material will reveal a warning mark, leave residue, change color or lose its original appearance.

             This makes it an effective solution for brand protection, product authentication, warranty control, logistics security and anti-counterfeit packaging.

Full transfer VOID material leaves the entire hidden security message and adhesive layer on the applied surface after removal.  The lift itself becomes no more sticky, couldn’t stick again. It provides strong and permanent tamper evidence, making it suitable for high-security packaging, electronics, logistics boxes, document sealing and asset protection.
