Abstract :
In this study, the effect of various factors on the permeability of CO2 and O2 gases on light polyethylene can be investigated. temperature, gas pressure and polymer thickness factors affect the permeability of gases. Various models such as DSC model and a device with ASTM standard and barometric method were used in the measurements. the results of the mentioned models show that with increasing temperature, the coefficients of permeability and permeability and solubility increase. also, increasing the pressure reduces the passing coefficient by a certain amount. But after a certain amount, the increase in pressure does not work. also, increasing the pressure has no effect on the permeability coefficient. In the case of solubility coefficient, increasing to a pressure range reduces this coefficient, then reaches a constant value.
