A polyethylene resin comprising from 44 to 55 wt % of a high molecular weight polyethylene fraction, and from 45 to 56 wt % of a low molecular weight polyethylene fraction; the high molecular weight polyethylene fraction comprising a linear low density polyethylene having a density of from 0. The boot cover assembly is selectively coupled to both the first rotational member and the second rotational member. During operation of the system, relative movement between the output face and the substrate support is accomplished.
