The mechanism embeds a hidden paper strip in the lid groove; after filling and sealing with double-sided tape, a consumer pulls a string that severs the strip and releases the lid in one smooth motion. The R&D team validated the system through resistance and usability tests to prevent tearing or string jams and confirmed it can be scaled to any coffret size for categories such as fragrance, cosmetics, jewelry, chocolates and spirits. Verpack also revealed a new printed wedge insert produced on single-flute cardboard that is offset-printed, die-cut and automatically glued.
