A closed-form solution for diffusion in two dimensions is obtained for impression creep of a thin film by a straight punch. The results show that for a rigid impermeable substrate the penetration rate is proportional directly to the thickness of the film and inversely to the square of the punch width. Without the substrate the penetration rate is inversely proportional to the thickness of the film and independent of the punch width.
