Japan’s leading potato chip producer Calbee Inc. is set to begin shipping selected flagship potato chip products in black-and-white packaging from late May, according to Kyodo News, as tightening supplies of naphtha — a petroleum-derived material widely used as a printing ink solvent — create packaging material constraints linked to conflict in the Middle East.

According to the report, the temporary packaging adjustment will affect core SKUs including Potato Chips Lightly Salted and Consommé Punch, with Calbee already informing retailers of the upcoming shift. The move reflects how geopolitical instability is now extending beyond fuel and logistics into packaging substrate availability, creating direct operational implications for food manufacturers.

While the product itself remains unchanged, the packaging downgrade highlights the vulnerability of snack and food processors to upstream petrochemical disruptions. Naphtha plays a critical role not only in plastics production but also in inks and related packaging inputs, making shortages particularly relevant for high-volume consumer packaged goods manufacturers reliant on branded shelf presence.

Kyodo also cited an industry and consumer group survey released in late April indicating that more than 70% of around 100 respondent companies said they would likely raise prices if naphtha supply concerns continue. For potato processors and snack manufacturers, this points to potential dual pressure: packaging simplification in the short term and broader cost inflation if raw material tightness persists.

For the potato processing sector, Calbee’s response may serve as an early example of how manufacturers could prioritize production continuity over brand aesthetics when packaging inputs become constrained. The development also underscores how Middle East instability may increasingly affect downstream food sectors through less visible but operationally significant industrial material shortages.
