  The mechanical and transport properties of jammed materials originate from an
underlying per- colating network of contact forces between the grains. Using
extensive simulations we investigate the force-percolation transition of this
network, where two particles are considered as linked if their interparticle
force overcomes a threshold. We show that this transition belongs to the random
percolation universality class, thus ruling out the existence of long-range
correlations between the forces. Through a combined size and pressure scaling
for the percolative quantities, we show that the continuous force percolation
transition evolves into the discontinuous jamming transition in the zero
pressure limit, as the size of the critical region scales with the pressure.
