dispensing a first stretch film having a first upper lateral side edge and a first lower lateral side edge from a first stretch film roll;
edging at least one of the first upper lateral side edge and the first lower lateral side edge to obtain an edged first stretch film having a first edge width;
passing the edged first stretch film through a pre-stretcher;
wrapping the edged first stretch film around the palletized load; and
