Printpack debuts 'hidden ink' technology

Printpack, Atlanta, said it introduced a new technology at PACK EXPO Las Vegas that allows brands to interact with and engage consumers. The technology — using a proprietary process Printpack invented — allows photochromic ink to be hidden within standard graphics and remain invisible until exposed to sunlight.

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, Printpack said.

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