Japan’s biggest snack maker has been forced to use black-and-white packaging for some flagship products because of ink ingredient shortages caused by the strait of Hormuz blockade.

Calbee, whose potato chip brands in particular are known for brightly coloured bag designs, said 14 of its products would switch to monochrome branding by the end of May.
