The innovative Covert-Hologram Seal presents as a simple packaging seal that is transparent and inconspicuous. The first time the seal is opened, however, a hologram emerges that shows various inscriptions and design elements in different colors, depending on the viewing angle. As the holographic effect is irreversible, the seal’s fully transparent original condition cannot be restored. This enables manufacturers, suppliers, and patients to determine at a glance whether the medicine is an originally packaged product that has not been opened previously.
Covert anti-counterfeiting features embedded in the specialty closure seal add extra security. By combining the reliable first-opening indication required by the EU Directive with additional counterfeiting protection in a single seal, the Covert-Hologram Seal helps enhance security throughout the supply chain.
