The gas permeability of high barrier film, bilayer film, polypropylene film and biaxially oriented polypropylene film at 4, 10, 25 and 30℃ were measured by small bag method. The influences of temperature on the coefficient of gas permeability and coefficient ratio of gas permeability were analyzed. The results suggested that the gas permeability coefficients of various films increased with the rising of temperature. When the temperature increased, the coefficient ratio of gas permeability of high barrier and bilayer films decreased significantly, while the coefficient ratio of gas permeability of BOPP and PP films increased slowly. At the same temperature, the gas permeability of PP film was the best of them, followed by BOPP film, the gas permeability of high barrier and bilayer films were much lower. The relationship between permeability coefficient and temperature was in accordance with Arrhenius equation, and a linear relationship between logarithmic values of gas permeability coefficients and the inverse of absolute temperatures was indicated.
