There's a practical reason chips bags are mostly air tho.

Yes. Helps to keep your arteries slightly larger.

It's so you don't get a bag full of crumbs.

No one in the history of civilisation has complained about too many broken chips in a bag.

When people started complaining about the amount of air being included in the bag, “prevents broken chips” was the bs marketing PR line put out. It’s just not true.

You know the easiest way to prove it’s bs? Pringle’s have introduced more air into their cans at the same time. Why? To match the shrinkflation of their competitors. Because adding air to a can of Pringle’s can only result in MORE broken chips. Which, again, no one in the fucking world has ever complained about.

I am absolutely sad when I get a bag of broken chips. And it definitely works you can test it yourself with some ziplock bags. There most likely is some shrinkflation hidden in that air, but the majority of it probably is playing an important part for people like me who love their chips but hate the crumbs.

But you’ll get a bag 3/4 with not broken chips and 1/4 with broken chips on average… ideally for the same price as the half full bag you get now that still may have more or less broken chips, depending on how it was transported.
