I like the convenience of the pre-wrapped slices (especially as unwrapped slices have a tendency to refuse into a single block). Kraft, for a while, had Pasteurized Process American Cheese individually wrapped, which I bought, but Pasteurized Process American Cheese Food is still fine. Unfortunately, just about everybody has switched to Pasteurized Processed American Cheese PRODUCT, which I find to be definitely inferior (and, apparently, has no FDA definition, unlike pp cheese and pp cheese food).
