White labeling is frequently more profitable than selling a name brand product because you don't have to spend money on marketing, but due to the different level of quality in most store brand products, the suppliers generally prefer to leave their brand off the package and put only the legal minimum identifying info require. As a result, unless you actually work for one of the brands involved (the store or the supplier) it's extremely hard to know who the supplier is. But every store brand product you buy in a major U.S. retail chain is made by a manufacturer of a name brand product in the same space.
