The results of studies of thinning free water-in-oil emulsion films stabilized by solid particles by the Applied Pressure Drop Technique (APDT) are reported. The quasi-equilibrium film thickness achieved by slow increasing the pressure drop was smaller than the rupture thickness obtained by sharp increasing the pressure. It is shown that non-equilibrium films ruptured with thicknesses corresponding to adjustment of the packing of solid particles in the films. It is supposed that the restructuring package is the cause of the earlier breakthrough of the film.
