The applicator comprises a liquid and air impervious sheet carrying on one surface thereof means holding a substantially uniformly distributed supply of processing liquid. The applicator is initially provided on one end of the film component in a releasably sealed folded configuration wherein the impervious sheet forms an impervious enclosure about the liquid holding means and it is movable therefrom to an unsealed extended configuration to locate the liquid holding means in liquid yielding contact with the given area of the film component outer surface.
