Kroger Private Label Potatoes Is There Any Way To Find The Manufacturer Of A Private Label Product?

Is there any way to find the manufacturer of a private label product? - kroger private label potatoes

For example, if you know the manufacturer:
Kroger Potato Chips (Kroger)
Granola Bar Great Value (Walmart)
Private Selection frozen blueberries (Kroger)

Is there a way to solve them? Retailers do not make these things themselves - they pay the manufacturers and packers to do for them.
