ProSecure tamper protection for pharmaceutical packaging

Schreiner Group : 15 April, 2009  (Application Story)
Bayer Healthcare gains safer packaging for pharmaceutical products thanks to "proof of first opening" seal developed jointly between Schreiner MediPharm and ProSecure
ProSecure tamper protection for pharmaceutical packaging
Today's pharmaceutical packaging has to meet exacting demands. A high level of user comfort combined with safe handling is a key requirement. To provide physicians and patients with proof of the product packaging's integrity and to make opening the pack particularly easy and comfortable for the user, Bayer Healthcare was seeking a specialty security seal for its highly successful product Levitra. The pharmaceutical corporation commissioned the experts from Schreiner MediPharm and Schreiner ProSecure to develop such a seal.

Bayer Healthcare specified exacting requirements for the project, summarized as follows: "Samples of the ED drug Levitra are sent to patients and physicians. A closure seal that is particularly easy to handle and can be used to close the packaging again several times is required to afford users a high level of comfort and convenience. In addition, the seal must provide clearly visible 'proof-of-first-opening' and must not be non-destructively detachable from the substrate." These complex requirements were to be met by a single solution.

The development resulted in a tailor-made Wallet-Seal incorporating additional functional features: a starter tab and an individual void effect. In addition, the seal uses a special adhesive adapted exactly to the particular requirements of the solution and the substrate.

The non-adhesive, handy starter tab facilitates opening the packaging. It is used to lift the void seal area, which allows multiple resealing of the wallet, from the substrate. When the seal is opened for the first time, the void message "OPEN" appears in this area. The message has a different color than the seal and remains permanently visible. To prevent undetected removal of the seal, the rear area of the seal is affixed to the cardboard packaging with a special, permanent adhesive. Any peel-off attempt thus causes irreversible damage to the packaging.

The development by the two experts for secure marking and closure solutions has resulted in a seal which meets exacting tamper and counterfeit protection demands. It is custom-tailored to the product packaging and optimally integrated into Bayer Healthcare's manufacturing processes. In addition, the convenience and functionality of the Wallet-Seal enhance the packaging and thus contribute to Levitra's success on the market as a comprehensive solution that adds value at all levels.
