Determination of the permeability of polyethylene and polypropylene plastic films against O2 and CO2

The oxygen and carbon dioxide permeability of the packaging plastic films is a very important parameter in the Modified Atmosphere Storage of agricultural products. A study was conducted to determine the influences of the type and thickness of packaging plastic films against oxygen and carbon dioxide. The materials used in this research consisted of Polyethylene (PE) and Polypropylene (PP) in three different thicknesses. Permeability measurements of the plastic films were carried out based on the Kubik and Zeman method with some modifications. The results showed that the type and thickness of the plastic film significantly influenced the transport properties of the plastic film consisted of the permeability against oxygen, carbon dioxide and the ratio of those two values (p
