Popis: The tensile properties of starch fiber (SF) and native starch (NS) filled polyvinyl alcohol were investigated in this study. Polyvinyl Alcohol (PVA) was blend with starch fiber as well as native starch. Prior to compounding process, PVA was plasticized with 30 phr glycerol as well as 10 phr distilled water. A solution casting method was used to prepare the SF-PPVA and NS-PPVA film sheet. Based on the tensile test results SF filled PVA recorded the highest tensile strength (20.015 MPa) as compared to NS filled PVA (12.302MPa). The tensile strength of the blends film was depending to the interfacial adhesion between matrixes in the blends. In spite of that, NS filled PVA have noted the highest elongation during the test. SF and NS played important role in affecting the blends matrix through disturbing the arrangement of continuous phase of PVA.
