Printpack (printpack.com) debuted a new way for brands to interact and engage with consumers at this year’s PACK EXPO Las Vegas. The technology – utilizing a proprietary process invented by Printpack – allows for photochromic ink to be hidden within standard graphics and remain invisible until exposed to sunlight. A sample application of the technology, where an observer can see the package transform firsthand, was on display at the Printpack booth.

The process represents the first time photochromic ink has been applied to a flexible film, giving brand owners in any market capable of utilizing flexible packaging new options for interacting with their customer base. Interactive packaging is proven to capture consumer attention and encourages engagement with the brand in a meaningful way.

“This type of packaging application can truly set a brand apart by adding depth to the consumer experience,” says Mark Brogan, director of technology and innovation at Printpack. “It can make all the difference when it comes to purchasing decisions.”

Applying photochromic ink has been a challenge for the flexible packaging industry for years, particularly in high speed production environments – in turn limiting options for brand owners looking to differentiate their product. Printpack’s R&D team designed the innovative process to apply the ink while still upholding the integrity of the packaging design and graphics to the highest standards.
