The result from mechanical properties of Krue Manoy films blended added concentration of glycerol are the best forming. Krue Manoy films blended added more concentration of glycerol resuted in the increase in the thickness but the significantly increase in tensile strength and percentage of elongation. As compared Krue Ma-noi films blended added concentration of glycerol at 25 by weight per gram of dry weight of Krue Ma-Noi the result not showed water vapor transmission
