Thermo Dual-Mark Encrypted Security Material

ZOLO has introduced a high-security anti-counterfeiting material featuring a dual-verification mechanism. When exposed to heat, the material reveals a pre-set hidden pattern or text; upon cooling, it reverts to its original state, enabling instant, tool-free on-site verification. Furthermore, it incorporates a composite fragile or "VOID" structure—leaving a visible trace immediately upon peeling—to prevent the label from being transferred.
