Coors cans turn blue due to the innovative color-changing thermochromic ink technology developed by Chromatic Technologies Inc. (CTI). This incredible ink is what creates the visually striking blue mountains on the can when it becomes cold enough. The story behind this fascinating feature dates back to 2002 when our founder, Barry L. Sherman, approached Coors with the idea.
At the time, CTI was already known for its expertise in developing specialty inks, including those that change color with temperature. Barry saw an opportunity to collaborate with Coors and create a unique packaging experience for their customers. Together, we embarked on a journey to develop a thermochromic ink that would be perfect for Coors' cans.
The goal was to create an ink that would be sensitive to temperature changes and would visually indicate when the beer inside the can was cold and ready to be enjoyed. After extensive research and development, we successfully formulated a thermochromic ink that achieves this effect. When the can reaches a specific temperature threshold, the blue mountains magically appear, signaling that the beer is at its optimal serving temperature.
The process of developing this ink was not without its challenges. It required a deep understanding of both the science behind thermochromic inks and the unique properties of aluminum cans. We had to ensure that the ink could withstand the rigors of the canning process, including the high temperatures and pressures involved. It also had to be food-safe and meet all regulatory requirements.
To test and refine the ink, we conducted countless trials and experiments. We exposed the cans to various temperature conditions, both in controlled environments and real-world scenarios. Through this iterative process, we fine-tuned the ink formulation to achieve the desired color change and durability.
One of the most exciting moments was when we finally presented our color-changing cans to Coors. Seeing their enthusiasm and appreciation for our innovation was incredibly rewarding. It was a proud moment for both CTI and Coors, as we knew we had created something truly unique and memorable for beer lovers.
Since its introduction, the blue mountains on Coors cans have become an iconic symbol of the brand. They not only add visual appeal to the packaging but also serve a functional purpose by indicating when the beer is chilled to perfection. This feature has garnered attention and praise from consumers worldwide, further solidifying Coors' position as a leader in the industry.
The reason why Coors cans turn blue is because of the thermochromic ink technology developed by Chromatic Technologies Inc. This innovation adds an extra element of excitement and anticipation to the beer-drinking experience, making Coors cans stand out from the crowd.
