Abstract
The permeability (P) and Diffusivity (D) of d‐limonene vapor in nine polymeric sealant films were measured and compared at a vapor concentration of 0.719 mg/L over the range 25–45°C. The sorption of d‐limonene (qs) was determined by a temperature programmed desorption (TPD) method. Equations to predict P and D for the different films were derived as a function of qs or temperature (Tmp) of differential scanning calorimeter measured melting points (DSCmp) of the films. Results indicated a tendency of test films with smaller values of qs and higher Tmp to have higher barriers against loss of d‐limonene due to absorption.Keywords
