  We present a broad class of spherical thin shells of matter in F(R) gravity.
We show that the corresponding junction conditions determine the equation of
state between the energy density and the pressure/tension at the surface. We
analyze the stability of the static configurations under perturbations
preserving the symmetry. We apply the formalism to the construction of charged
bubbles and we find that there exist stable static configurations for a
suitable set of the parameters of the model.
