We consider two non-linear $f(R,L_m)$ functional forms, specifically, $f(R,L_m) = \\frac{R}{2} + \\lambda R^2 + \\alpha L_m$ and $f(R,L_m) = \\frac{R}{2} + L_m ^\\beta + \\gamma$ representing a minimal coupling case. We derive the corresponding Friedmann-like equations for both the assumed models in the FLRW background, and then we present the impact of the model parameters along with the parameter of bouncing scale factor on the equation of state parameter, pressure, and the energy density.
