Permeation of CO 2 and O 2 through a low density polyethylene film was studied with CO 2 ‐N 2 mixtures in the temperature range 263‐283 K, and with CO 2 ‐O 2 ‐N 2 mixtures in the range 257‐313 K. The temperature dependence of the permeabilities of these gases agreed with the Arrhenius expression. The activation energy for carbon dioxide diffusion was between 3.53 × 10 4 and 3.74 × 10 4 J/mol; the activation energy for oxygen diffusion was 3.13 × 10 4 J/mol. The pre‐exponential constant for oxygen was higher than that of carbon dioxide in various mixtures. It was also found that the pre‐exponential constant of carbon dioxide decreased with increasing CO 2 concentration in the mixtures.
