Polyester Safety and Warning Labels with Holographic Silver VOID Tamper-Evident Anti-Counterfeit Feature

Overview

The B-236G Polyester Safety and Warning Labels are holographic silver VOID tamper-evident labels designed for anti-counterfeiting and anti-tampering applications.
Featuring a full transfer VOID security structure, this label leaves a clear holographic “VOID” message on the application surface once removed, providing immediate visual evidence of tampering.

Manufactured with a durable Polyester (PET) face material and high-performance acrylic adhesive, B-236G labels are widely used in electronics warranty sealing, logistics security, document protection, and high-value product identification, where product integrity and authenticity are critical.

Features
