down voted by people who think any Kraft ceese is real cheese?

It is, you're just using the FDAs god-awful definition from over 100 years ago that only cheese made in the specific traditional way is "cheese"

Kraft singles are American cheese: typically a cheddar and Colby jack mix with 2 specific chemicals added to allow water to stay in the mixture better. Boil them together, spread thinly and let harden.

Kraft singles have more chemicals and a more complex process so they can get as thin as they do, but they're cheese by any normal person's definition.

here's a great video by NileBlue on the subject
