1. A method for securing a palletized load, the method comprising the steps of:
dispensing a first stretch film having a first width, a first upper lateral side edge and a first lower lateral side edge from a first stretch film roll inserted over a first support member extending from a base surface;
dispensing a second stretch film having a second width, a second upper lateral side edge and a second lower lateral side edge from a second stretch film roll inserted over a second support member provided in a side-by-side relationship relative to the first support member;
dispensing a third stretch film having a third width, a third upper lateral side edge and a third lower lateral side edge from a third stretch film roll inserted over the second support member;
fully overlapping the first stretch film and the second stretch film, comprising edging at least one of the second upper lateral side edge and the second lower lateral side edge to obtain an edged second stretch film having a second edge width;
fully overlapping the first stretch film and the third stretch film, comprising edging at least one of the third upper lateral side edge and the third lower lateral side edge to obtain an edged third stretch film having a third edge width, wherein the second edge width is larger than the third edged width;
passing the combined stretch film through a pre-stretcher; and
wrapping the first, second and third stretch films around the palletized load.
