Abstract:: Taking ‘Pinot Noir’ grape seed/skin as experimental materials，the test was conducted with a kind of preservative film which based on chitosan and sodium alginate adding grape seed polysaccharide/flavones and grape skin polysaccharide.The effect of the same concentration of grape seed polysaccharide/flavones and grape skin polysaccharide on the same properties of chitosan and sodium alginate were studied.The results showed that grape seed polysaccharide had greater effect on the tensile elongation and water vapor permeability of chitosan membrane，grape skin polysaccharide had greater effect on the absorption rate of chitosan membrane and the tensile elongation and water vapor permeability of alginate membrane，however，there were no effect of three kind of natural extracts on the blocking oil properties of chitosan membrane and sodium alginate membrane.
