A Short History of Crisp Packet Design

Why the Packet Matters More Than We Admit

We spend a great deal of time arguing about crisps themselves — the crunch, the seasoning, whether the last three in the bag count as a portion. The packet gets much less attention, which is a shame, because it is doing far more work than we give it credit for. A crisp packet has to survive a lorry, several months on a shelf, and a jolting journey home in a rucksack. It has to be understood from two metres away across a crowded shop floor, opened without exploding, and folded down small enough to fit a coat pocket. That it also carries sixty years of social signalling is a happy accident.

From Paper Twists to Sealed Foil

The earliest British crisps arrived in twists of greaseproof paper, often with a little paper bag of salt tucked inside so the customer could season to taste. These packets were cheap, semi-transparent and printed in one or two colours at most. The crisp was visible through the paper, which read as honesty: you could see what you were buying.

The arrival of sealed foil-laminate bags in the middle of the twentieth century changed the grammar of the whole thing. Opaque, glistening and moisture-proof, they kept crisps fresh for months rather than days and handed manufacturers a flat, printable surface roughly the size of a postcard.

• Twist packets: narrow, awkward, impossible to reseal, sold by weight from a box behind the counter.
• Foil laminates: airtight, opaque, sold on the promise of freshness rather than the sight of the product.
• Pillow packs: filled from the top with a gusseted base, later designed to stand upright on the shelf — a small engineering decision that gave the packet a whole new job as a billboard.

The Colour Code That Never Quite Agreed

Here the history becomes enjoyably messy. In Britain, salt and vinegar drifted towards blue, cheese and onion towards green, and ready salted towards red. But regional producers and supermarket own-label lines muddied the water beautifully: some packed cheese and onion in blue, some put salt and vinegar in green, and a few reversed the pair entirely as a small act of defiance.

The inconsistency makes sense once you look at how the bags were made. Packets were designed regionally, printers worked with a limited number of colour plates, and there was no central authority to lay down the law. Colour was an economic decision before it was a branding one — and once a colour was associated with a flavour in your area, changing it risked confusing your regulars.

• Blue: cold, sharp, expectant — the natural home of vinegar.
• Green: herbal and savoury, borrowed from onion, chive and "garden" flavours.
• Red: the default, the plain bag, the safe choice for a party you are not especially invested in.
• Orange, purple and black: novelty, "flame-grilled" ambitions, or premium pretension.

Typography, Badges and the Shouty Decades

If you lay packets from the 1970s, 1980s and 1990s side by side, the noise level visibly rises and then falls again. The seventies leaned on chunky slab-serif lettering, rotating wordmarks and hand-drawn comic flourishes. The eighties went louder still: starbursts, ribbons, cartoon mascots and the great inflationary slogan of the age, 25% extra free.

That era of packets carried a great deal of small print — statutory weights in grammes, ingredient lists growing by the year, promotional rules for competitions involving tokens, caravans and holidays. The bag became a nervous document as well as an advertisement.

By the late nineties, design had calmed down. Wordmarks were simplified, illustrations reduced to a single clean image, and the typography switched to bold geometric sans-serifs with generous spacing. It was the visual equivalent of a deep breath, and it made older packets look instantly dated.

The Premium Turn: Kraft Paper and Quiet Confidence

The hand-cooked movement of the 1990s and 2000s introduced a completely different design language. Thick-cut crisps arrived in matte bags that imitated uncoated brown kraft paper, printed in black or a single muted colour, with small type and almost no hierarchy. Where the mainstream bag shouted, these murmured.

Alongside it came the return of transparency. A clear window patch set into a matte bag let you see the crisps again, but as proof of quality rather than economy. Sharing bags grew larger and glossier, then grew slightly smaller again as weights crept down by ten grammes at a time — a change usually noticed by customers long before it was admitted by anyone else. Resealable strips, meanwhile, finally solved a problem that had irritated shoppers since the paper twist.

Reading the Shelf Like a Historian

Walk down any crisp aisle and you are reading a compressed social history. The colour blocks tell you which flavours are considered safe and which are considered fun. The fonts tell you who the packet thinks you are: comic lettering for a school lunchbox, restrained sans-serif for a dinner party, script for a farm shop.

Packets also reveal what we distrust. When a bag shows you the crisp through a window, it is admitting that we have stopped believing printed promises. When it prints "absolutely no artificial colours", it is answering a worry that did not exist in 1965. When it lists the farm, the potato variety and the frying oil, it is selling transparency as luxury.

And when a bag goes out of its way to look old — faux-heritage crests, faded stripes, a font lifted from a 1950s grocery advert — it is trading on nostalgia for a Britain of corner shops and loose sweets that most of us never actually experienced. That is the neatest trick in the whole business. The next time you tear open a bag, spare a thought for the design team. They had about a second to convince you, and they have been quietly winning that argument for decades.
