An attempt is made to present the contribution of the scalar unparticle on the Z-production cross-section at International Linear Colliders (ILC) with polarized initial beams in the Randall-Sundrum model. The cross-sections depend strongly on the polarization of $e^{ -}$, $e^{ +}$ initial beams, the center of mass energy $\sqrt{ s} $, the scaling dimension $d_{ U}$ of the unparticle operator $\mathcal{ O}_{ U}$ and the energy scale $\Lambda_{ U}$. The results indicate that with the effect of the scalar propagators in the s-channel, including radion, Higgs and scalar unparticle, the cross-section for the ZZ production is enhanced and larger than that in the Standard model under the same conditions.
