In order to improve the properties of rice straw fiber film, one factor contrast test method was employed. Plasticizer
type was chosen as input variable, dry tension strength and elongation, wet tension strength and elongation, bursting strength and
tearing strength were chosen as indexes. The results showed that there were significant differences among the means of dry tension
strength, dry elongation and bursting strength of different plasticizers; there were not significant differences among the means of wet
tension strength, wet elongation and tearing strength of different plasticizers; for dry tension strength and elongation, glycerol had a
significant difference with sorbitol and PEG, no significant difference was observed between sorbitol and PEG, dry tension strength
added glycerol had been reduced 6.8% compared with that added sorbitol, reduced 9.5% compared with that added PEG; elongation
had been improved 6.1% and 9.4%, respectively; for bursting strength, sorbitol had a significant difference with glycerol and PEG, no
significant difference was observed between glycerol and PEG; bursting strength added glycerol and added PEG had been improved
6.9% and 5.6%, respectively compared with that of the added sorbitol. The results provided a theoretical reference for further
improving the straw fiber film manufacturing process.
