Patent

CA 2488181

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 single-walled carbon nanotube material based on the weight of the film. 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).

Une méthode d'augmentation du taux de transmission des gaz d'une pellicule d'emballage qui comprend la fourniture d'une pellicule d'emballage comprenant au moins 0,001 % de poids de matériel nanotube de carbone monoparoi fond sur le poids de la pellicule. La pellicule d'emballage est exposée à une quantité d'énergie de rayonnement efficace afin d'augmenter le taux de transmission à l'oxygène de la pellicule par au moins 100cc (STP)/m2 par jour (1atm., 0 % HR, 23 oC).
