1. A method of wrapping a palletized load, comprising:
providing an apparatus comprising:
a first wrapping system having a first support bar, a first set of adjustment arms coupled to the first support bar, and a first spool of stretch film configured to feed stretch film through the first set of adjustment arms, and banding a top edge and a bottom edge on at least one roll of the stretch film from the first spool by passing the stretch film from the first spool through the first set of adjustment arms;
a second wrapping system having a second support bar, a second set of adjustment arms coupled to the second support bar, and a second spool of stretch film configured to feed stretch film through the second set of adjustment arms, and banding a top edge and a bottom edge on at least one roll of the stretch film from the second spool by passing the stretch film from the second spool through the second set of adjustment arms;

overlapping the banded stretch film from the first spool with the banded stretch film from the second spool to create a composite stretch film, the composite stretch film comprising a plurality of alternating sections formed by the stretch film from the first spool banded at the top and bottom edge and the stretch film from the second spool banded at the top and bottom edge, overlapped such that one of the banded top edge and the banded bottom edge of the stretch film from the second spool is positioned between the banded top edge and the banded bottom edge of the stretch film from the first spool and the other of the banded top edge and the banded bottom edge of the stretch film from the second spool is positioned not between the banded top edge and the banded bottom edge of the stretch film from the first spool such that it is not overlapped with the stretch film from the first spool; and
wrapping the composite stretch film around the palletized load.
