Abstract: The mechanical and barrier properties of Pulluan films were studied. X - ray and Scanning Electron Microscopy (SEM) were also used to observe the surface and the crystallinity structures of pulluan films. Pullu an film were shown to have low oxygen permeability and high moisture permeability. The microstructure and the crystallinity structure of Pulluan films revealed that the Pulluan films formed from the solution containing 5% Pulluan and 5% giycerin exhibited high oxygen barrier property and tensile strenth.
