Thermochromic Ink Technology Changing the Look of Flexible Packaging

Developments have made way for the use of thermochromic inks on flexible packaging opening a new realm of communicating and customer interaction.

Printpack is revolutionizing thermochromic ink applications by creating technologies that can be applied to flexible labels and by expanding their color changing capabilities. Thermographic inks grab a consumer’s attention and differentiate a brand. Paired with a clever bit of creativity, such products provide a real visual knockout!

Color changing inks are not new to the packaging industry. Most commonly seen on cans or sticker applications, hurdles existed that made thermochromic inks incompatible with flexible packaging. Barrier strengths, bonding mechanisms and performance can be compromised by the chemical properties of the inks. Printpack’s R & D team developed technologies to overcome those hurdles and is producing packaging that meets all of the performance standards while enhancing the customer experience.

Children enjoy packaging that blends together their favorite products along with visual stimulation. Printpack has worked with ink developers to ensure that the chemicals in these inks are not harmful when they come in contact with skin. Thermochromic inks on flexible packaging allow a child to grip and manipulate the color of the packaging in more diverse ways.

Commonly used to gauge temperature, manufactures are able to communicate when an item is ideal for consumption right on the package. Printpack is creating thermographic color to color change combinations that have not been accomplished by other film or ink developers. New color combinations allow a manufacture the ability to customize the graphics for their specific promotional needs.

Printpack’s advancements in thermochromic ink technology demonstrate their commitment to delivering innovative packaging solutions. Since their conception in 1956, Printpack has always been at the forefront in R&D developing new ways to make packaging better.
