BRADY VOID Pattern Tamper Evident Security Labels, Polyester, Red, 38.1 x 19.05 mm, 1000 Labels per Roll

Tamper evident security labels with a VOID pattern that reveals upon removal, providing clear evidence of tampering. These red polyester labels measure 38.1 x 19.05 mm and come in a roll of 1000. The permanent acrylic adhesive adheres strongly to smooth, non-porous surfaces like metal, plastic, and glass. When someone attempts to peel off the label, the VOID pattern remains on both the label and the surface, making tampering immediately obvious. Ideal for securing assets, warranty seals, and sensitive equipment.

Advantages

These labels offer a reliable tamper indication mechanism: any attempt to remove them leaves a visible VOID pattern, deterring unauthorized access. The polyester film provides excellent durability, resisting water, oil, and moderate chemicals. The permanent acrylic adhesive ensures the label stays in place until tampered with, and the non-transferring characteristic means the VOID message appears on both the label and the substrate, leaving no doubt about tampering. With a wide operating temperature range from -20°C to 80°C, they perform in various environments.

Recommendations

For best results, apply labels to clean, dry, smooth surfaces at room temperature. Ensure the surface is free of dust, oil, and contaminants to maximize adhesion. Store unused labels in their original packaging in a cool, dry place. When tampering is suspected, inspect for the VOID pattern on both the label and the surface. These labels are intended for one-time use; once removed, they cannot be reattached without showing evidence.
