Invisible design hidden within a package’s visible graphics
Printpack has introduced a new photochromic technology for flexible packaging, This allows brand owners to create an invisible design hidden within a package’s visible graphics. This hidden design is only revealed when a consumer carries the bag into the sunlight. The concealed design can be any graphic that would surprise and delight consumers as they interact with the package outside. The unique technology makes this a fantastic way to have consumers engage with the package on a new level.
The first-of-its-kind packaging application allows for photochromic ink to be hidden within standard graphics and remain invisible until exposed to sunlight. The process allows for the application of photochromic ink on a flexible film while still upholding the integrity of the package design and graphics to the highest standards.
