Two Color VOIDOPEN Material for Full Transfer Tamper Evident Labels

Two Color VOIDOPEN Material is a full transfer tamper evident label material designed to reveal a clear two-color VOIDOPEN message after removal. Before opening, the hidden security message remains invisible. Once the label is peeled off, the adhesive layer transfers the VOIDOPEN message completely onto the applied surface.

This material is suitable for security labels, packaging seals, warranty labels, logistics cartons, electronics packaging, retail boxes, and anti-counterfeit brand protection projects. Compared with standard one-color VOID materials, the two-color effect creates stronger visual contrast and makes tamper evidence easier to identify.

How Two Color VOIDOPEN Material Works

Two Color VOIDOPEN Material uses a multi-layer full transfer structure. The hidden message is built into the security layer and remains invisible before removal. When peeling is attempted, the security layer separates and leaves the two-color VOIDOPEN message on the package surface.

After removal, the message cannot be restored or hidden. This irreversible transfer effect helps prevent label reuse, package resealing, product switching, and unauthorized opening during storage, shipment, retail handling, or after-sales inspection.

Why Choose Two Color VOIDOPEN Material?

Two-color tamper evident materials are useful when customers need stronger inspection visibility than standard single-color VOID labels. The dual-color message helps warehouse staff, distributors, inspectors, and end users quickly confirm whether a package has been opened.

This material is also suitable for brand protection projects where the security label must provide both functional tamper evidence and a more professional appearance. The two-color VOIDOPEN effect can be customized according to customer branding, package color, warning message, and inspection requirements.

For high-value products or branded packaging, the full transfer two-color message provides a visible warning that the package has been opened. This helps reduce product switching, unauthorized inspection, warranty fraud, and package resealing.

Two Color VOIDOPEN Material vs Standard VOID Material

Standard full transfer VOID materials usually show a single-color hidden message after removal. Two Color VOIDOPEN Material adds a dual-color visual effect, making the transferred message clearer and more noticeable on different packaging surfaces.

For basic sealing applications, standard VOID material may be enough. For brand protection, retail packaging, electronics security, and higher-visibility tamper evidence, two-color VOIDOPEN material provides a stronger inspection effect.

Customization Options

Hanksec can customize Two Color VOIDOPEN Material according to face material, surface color, hidden message, color contrast, adhesive strength, residue level, release liner, roll width, label size, and application surface.

Common customization options include VOIDOPEN text, VOID message, OPENED message, ABIERTO message, custom brand logo, serial number, barcode, QR code, warning text, and special anti-counterfeit pattern. Customers can choose roll materials for converting or finished labels for direct use.

Surface Compatibility and Testing

Before mass production, customers should test the material on the real application surface. Plastic boxes, coated cartons, paperboard, glass, painted metal, laminated packaging, and textured surfaces may show different adhesive bonding and transfer performance.

Important testing items include peel adhesion, message transfer clarity, color contrast, residue behavior, print readability, barcode scanning, liner release force, and final appearance after removal.

How Two Color VOIDOPEN Material Works

  Before opening, the tape’s hidden security message (“VOID OPEN”) remains invisible. Once removed, the adhesive layer completely transfers the message or custom design onto the applied surface—while the same message appears clearly on the tape’s surface. This dual indication ensures tampering is obvious and impossible to conceal or realign.
