Increasing the gas permeation rate of a packaging film comprising providing a packaging film comprising at least about 0.001% by weight of a fullerene material selected from spherical fullerenes, bowl-shaped fullerenes, multi-walled carbon nanotubes, carbon nanocones, and carbon nanoonions how to. The packaging film is exposed to an amount of radiation energy effective to increase the oxygen transmission rate of the packaging film by at least about 100 cc (STP) / m 2 . |
