Japan’s snack giant Calbee is temporarily switching several popular products to black-and-white packaging after the war involving Iran disrupted global supplies of petroleum-based chemicals used in color printing inks. The conflict has affected shipping routes and oil exports from the Middle East, causing shortages and soaring prices for materials needed to produce colorful food packaging. Beginning later this month, consumers in Japan will see grayscale versions of potato chips, shrimp snacks, and granola products on store shelves as the company works to conserve limited ink supplies. The unusual move highlights how geopolitical conflicts can ripple through global supply chains, affecting everything from energy markets to everyday supermarket products thousands of miles away.
