ELI5: How does Kroger (and other large grocery chains) make all of its generic brand food?

Kroger has a generic branded version of pretty much everything in their store. How do they make all of it? There are different recipes, molds, and entirely different production processes for most of this stuff. Do they buy each product off of someone else and put on their own packaging, or do they really make it all themselves? (And if so, where are all these factories?)

Many of Kroger brands are made in the same factory as the other more expensive brands. The cheaper price comes from a combination of buying direct form the manufacturer and not as high quality ingredients or parts.
Also a lot of time you are paying a premium for the well known that has nothing to do with the quality of the product.
Edited for spelling.
