Yeah, at a job I worked at before there were two differences between our branded product and the store brand: The packaging/label, and the amount of thickener so that it would have a slightly different texture. Otherwise, same employees making it on the same machines with the same ingredients.
They did always have that one small change in there though, so that it wouldn't be exactly the same. Nothing you'd ever notice as a customer. Just a technicality so that each one could claim their own unique formula.
I think with another type of product it wasn't the thickness but a slight difference in the ratio of the flavorings - more raspberry and less blueberry here, more blueberry and less raspberry there.
