Calbee Japan Snack Giant Black White Packaging Iran War Oil Ink Shortage

The Strait of Hormuz blockade disrupts naphtha supply, a key input for ink used in snack packaging. Calbee, a major Japanese snack maker, switches to black-and-white packaging to conserve ink. This is a supply_shortage channel affecting packaging costs and potentially brand presentation. Impact is Japan-specific for snack packaging, but global for naphtha/ink supply chains. Winners: alternative ink suppliers, non-Middle East naphtha exporters. Losers: Calbee (margin squeeze if packaging change affects sales), other Japanese food companies reliant on colored packaging.
