A two term Ginzburg-Landau Hamiltonian for the free energy density of n-layer systems is introduced. It is used to derive a distribution function for such systems and to obtain scaling laws involving the number of components. We discuss the validity of this mean-field theory for stretched polymers in two-dimensional space and for fluid membranes.
