We discuss the formation of large loops in adsorbed polymer layers when the bulk concentration C is large. This allows us to introduce a new characteristic length that corresponds to the extension of the loops in the bulk. We find that and increases from the screening length to the radius of the chains when concentration increases. This may be observed for instance by dilution of the solution subsequent to adsorption.
