Processes are disclosed for oxygen-tailoring polyethylene resin. Polyethylene
resin is conveyed through a feed zone, a melt-mixing zone and a melt zone. The
resin is contacted with oxygen in an amount of at least 40 parts by weight O2
per million parts by weight resin, and contacted with primary antioxidant downstream
of the point or points of oxygen contact. The oxygen-treated resin can be used
to make polyethylene film having improved gauge uniformity.
