In response to an ongoing ink shortage linked to the Iran war, Japanese snack giant Calbee has announced that some of its iconic potato chip bags will now feature a monochrome design. The conflict has led to significant disruptions in supply chains, particularly affecting the availability of oil and naphtha, key components in packaging materials. As a result, Calbee is shifting to black-and-white packaging to maintain its product supply on store shelves. This move reflects broader supply chain challenges faced by companies in the food industry, highlighting the unexpected impacts of geopolitical conflicts on everyday consumer goods.
