Abstract:
A method of increasing the gas transmission rate of a packaging film comprises providing a packaging film that comprises at least about 0.001 weight % of fullerene material selected from spherical fullerenes, bowl-shaped fullerenes, multi-walled carbon nanotubes, carbon nanocones, and carbon nano-onions. 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)/m2. day (1 atm, 0% RH, 23° C.).
