We investigate bounce cosmological models in the presence of a viscous fluid, making use of generalized holographic cutoffs introduced by Nojiri and Odintsov [Covariant generalized holographic dark energy and accelerated universe, Eur. Phys. J. C 77 (2017) 528, arXiv:1703.06372 [hep-th]]. We consider both an exponential, a power-law, and a double exponential form for the scale factor. By use of these models, we calculate expressions for infrared cutoffs analytically, such that they correspond to the particle horizon at the bounce. Finally, we derive the energy conservation equation, from the holographic point of view. In that way, the relationship between the viscous fluid bounce and the holographic bounce is demonstrated.
