The effects of pullulan and glycerol addition on the tensile properties, optical properties and barrier properties of edible film were studied. The result showed that the addition of pullulan dramatically improved the elongation at break, oxygen barrier, luminousness and tensile strength of edible film; when the amount is more than 50% (percentage by weight), the tensile strength and water vapor barrier decreases obviously; the addition of glycerol can both increase the elongation at break and optical properties of edible film, but the water vapor barrier decreases; when the dosage of glycerol is 20%, the combination property of the film is the best.
