Oh! So there's actually a solution to this, pretty low tech. Been around for a while.

It's called a fucking knife.

When I was a kid my mom used to get American cheese sliced behind the deli counter all the time and they always gave us the slices in a stack and it never combined.

I can't stand American cheese, nasty fake stuff, but I got cheddar cheese slices behind the deli the other week for the first time in awhile. Instead of just slicing it and giving it to me in a bag like every other time in my life, they individually wrapped every slice in a thin plastic. I got home and was like what in the plastic hell is this? So wasteful and it was a real PITA unwrapping it all.
