For use in clinical trials, the label must provide sufficient space for compulsory text. In addition, it must ensure that each investigational product has the same appearance, even in transparent syringe barrels. Depending on the required amount of text, a one- or two-layered wrap design is used for the syringe, each of which allows double sided printing per layer of film. Extensive, high opacity printing of the transparent material is required to do this.
The product solutions are based on a particularly long, one-layered wrap-around label named Pharma-Wrap and a two-layered label, the so-called Euro-Label. Very flexible film material is required, so that the label can be easily wrapped around the syringe with a small radius. The part of the label that is directly glued to the syringe consists of a tinted transparent film. This enables reliable neutralization of the syringe without obstructing the view of the contents. The remaining part of the label is printed on a white background, so that product information can be provided on both sides. The integrated peel-open tab enables easy opening and closing of the label.
These specialty labels increase flexibility, efficiency, and safety for the execution of clinical trials, because one single label variant can be used globally for marking the respective product, while blinding it at the same time.
