Hiball Energy teamed up with Ball Corp. to debut a line of reformulated sparkling energy waters and organic energy drinks in cold-activated, lightweight 16-ounce aluminum cans. The company’s decision to transition from 10-ounce glass bottles to 16-ounce aluminum cans was a result of consumer demand for a larger size with a more portable packaging option, it says. The new can features cold-activated graphics that use thermochromic ink from Chromatic Technologies Inc. When the cans reach a temperature of 45 degrees Fahrenheit, the bubbles on the can change from white to blue, indicating that the beverage inside is at the optimal temperature for drinking, the company says.
