Covert-Hologram Seal from Schreiner MediPharm Offers Tamper Protection Conforming to EU Directive


The innovative Covert-Hologram Seal is transparent, inconspicuous and thus appears like a simple packaging seal. However, the first time the seal is opened, an invisible effect becomes visible. A hologram emerges that shows various inscriptions and design elements in different colors depending on the viewing angle. The holographic effect is irreversible and the seal’s fully transparent original condition cannot be restored. Thus, manufacturers, suppliers, and patients can tell at first glance if the packaging has been previously opened or if the medicine is an originally packaged product.

Covert anti-counterfeiting features embedded in the specialty closure seal add extra security. Thus, the Covert-Hologram Seal effectively combines the reliable first-opening indication required by the EU Directive with additional counterfeiting protection in a single seal, enhancing security throughout the entire supply chain.
