Tokyo — Calbee Inc., Japan’s largest snack manufacturer, will temporarily switch 14 of its flagship products to black-and-white packaging as a global ink supply crunch triggered by the ongoing Iran conflict disrupts petroleum-based materials used in printing, forcing companies to conserve resources and stabilize production chains, May 14, 2026.
Calbee black-and-white packaging shift driven by Iran war supply disruption
The company announced this week that its iconic brightly colored snack packaging — including potato chips, shrimp crackers, and cereal products — will be replaced with monochrome designs starting May 25. The decision follows shortages of naphtha, a petroleum derivative essential in producing printing inks and plastics, as shipping routes and oil flows through the Strait of Hormuz remain unstable due to the Iran war.
Calbee said the change applies to 14 products and is designed to ensure “stable supply of products” despite “unstable supply affecting certain raw materials,” according to company statements reported by multiple outlets, including The Japan Times. The company emphasized that product quality and quantity will remain unchanged, even as packaging becomes noticeably stripped down.
Industry analysts say the move reflects broader vulnerabilities in Japan’s import-dependent manufacturing sector, where roughly 40% of naphtha is sourced from the Middle East. The disruption has been linked to the ongoing regional conflict, which has also impacted global shipping and energy markets.
Ink shortage highlights wider industrial impact of Middle East conflict
The packaging shift underscores how deeply the Iran war is affecting global supply chains beyond energy markets. According to reports from The Guardian, the shortage of oil-derived materials such as naphtha is straining ink production across Japan’s food and manufacturing sectors.
Similar coverage from Associated Press noted that companies are increasingly shifting to minimalist packaging strategies to conserve raw materials. The trend is not isolated to Calbee, with other Japanese manufacturers reportedly exploring similar cost-cutting measures in response to the crisis.
Energy economists have pointed out that disruptions in the Strait of Hormuz — a key global oil shipping route — have amplified price volatility and reduced availability of petrochemical inputs. These materials are critical not only for fuel production but also for inks, plastics, and fertilizers.
Japan reassures public despite visible supply strain
Despite growing corporate adjustments, Japanese government officials have sought to calm public concern. Authorities say national reserves and diversified imports are currently sufficient to prevent immediate shortages of naphtha or printing ink, even as geopolitical risks persist.
However, the visible shift in Calbee’s packaging has become a symbolic reminder of how global conflicts can filter into everyday consumer goods. The company, founded in 1949 and known for products like Kappa Ebisen shrimp chips and lightly salted potato chips, has not indicated how long the monochrome packaging will remain in place.
Analysts expect continued volatility in packaging and manufacturing inputs as long as energy flows remain disrupted, with ripple effects likely across Asia’s consumer goods industry.
