Walkers Crisps has announced a dramatic shift to black-and-white packaging for its entire product range, as the escalating conflict in Iran disrupts global supplies of ink pigments. The move, confirmed in a terse statement this morning, threatens to send shockwaves through the UK’s already fragile supply chain industry, with experts warning of a “logistics nightmare” that could push prices up for staples beyond just crisps.

The decision, effective immediately, means the iconic red, green, and blue packets of cheese and onion, salt and vinegar, and prawn cocktail will be replaced by monochrome designs. Walkers said the change was necessary because the Iran war has cut off supplies of titanium dioxide and organic pigments, which are also used in inks for food labels, packaging, and even paint. The company’s supply chain chief, Martin Chen, said: “We are facing an unprecedented shortage. This is not just about crisps. It is about the entire packaging ecosystem.”

The conflict in Iran, which has now entered its third month, has disrupted global shipping routes in the Persian Gulf, a key artery for chemical exports. The UK’s reliance on imports for 60% of its ink pigments has left the snack industry exposed. But the crisis is not limited to crisps. Food manufacturers across the board use similar inks, and industry bodies warn that the knock-on effect could hit everything from baked beans to biscuits.

For working families, this is another blow to the cost of living. One shopper, Jane from Rotherham, told me: “First it was the price of bread, now it’s the colour of crisps packets. It feels like everything is falling apart.” The reality is starker. The British Retail Consortium has already flagged a 12% increase in packaging costs this year, and this latest disruption could add another 5% to 8% on top. Supermarkets are preparing for shortages of non-essential items as manufacturers scramble to source alternative inks.

The logistics industry is bracing for a “perfect storm”. The Road Haulage Association has warned that delivery schedules will be hit because packaging lines need to be reconfigured. “This isn’t just a printer issue,” said one logistics manager who asked to remain anonymous. “We have to change the whole supply chain from factory to shelf. It will take weeks, if not months.”

Meanwhile, unions are watching closely. The GMB union, which represents many factory workers, has raised concerns about job security if production slows. “Workers cannot afford another hit to their wages,” said lead organiser Rachel Dawkins. “But if this drags on, we could see short-time working or even layoffs.”

The government has so far remained silent. Business groups are calling for an emergency taskforce to manage the crisis. But for now, the immediate impact is on the kitchen table. For millions of families, a bag of crisps is a small comfort. Now even that is being stripped of its colour.

This is not just a story about ink. It is a story about how a distant war reaches into the heart of British life. The real economy is fragile, and the cost is being passed on to the people who can least afford it. As one mother in Leeds put it: “First food prices went up. Now the packets are going grey. What’s next?”
