What is the point of individually wrapping cheese slices in plastic, only to cover a bunch of them in more plastic?
Title.
It feels like such a waste.
EDIT:This is the type of cheese I am referring to. It comes wrapped in a piece of plastic then bundled together with x more and all of them get covered in plastic
Food tech is kinda my area, so I went and did a little research and it turned into quite a ride. For cultural context, grilled (broiled in the US, I think) cheese and Vegemite is kind of a traditional Aussie snack. Just a slice of white bread with butter and Vegemite, slice of cheese on top, stick it under the grill.
The Kraft singles I remember from my childhood absolutely did not behave like anything resembling real cheese when you did this. It melted on the inside, sure. But the outside just dried out and turned into a kind of plasticky skin, then bubbled and burned. So you were left with this partially blackened and crunchy cling-film like skin disguising a thin layer of vaguely dairy-adjacent molten plastic goop that was guaranteed to stick to and sear the roof of your mouth. Then the skin came off in one piece and slapped you on the chin with the equally hot residue of said plastic goop. For some reason kids loved this.
I'm not sure when OP last ate them, but the Kraft singles I know got axed in like 2017 when Mondelez sold their cheese line to Bega. That makes it incredibly hard to track down the original formula to figure out what in the world they were really made of. They have, however, since been re-released and claim to be at least 45% cheese, which I suspect is a lot more than the ones I remember, probably does melt, and falls pretty squarely into the "processed cheese" definition according to FSANZ. There's no way in hell I'm buying some to try it though.
There is a How It's Made episode showing how Kraft singles are made somewhere. It's still cheese, but they also add more milk to make it meltier, as well as things like preservatives. It's kind of like a solidified bechamel.
Other brands of similar processed cheese slices tend to made entirely with oils with zero dairy. There is a definite difference in taste and texture comparing Kraft Singles, off-brand singles, and just plain cheddar though.
