Abstract

is research shows the performance of biodegradable plastic composite using tapioca starch (TS) and polypropylene (PP) as a primary matrix material with addition of sugar cane fiber cellulose (SCFC) as reinforcement and glycerol as additive plasticizer. The main objective of this research is to fabricate a biodegradable plastic packaging for food industries using an internal mixer method which produced the novel biocomposites that simply named as PTSG Biodegradable Hybrid Composite. The effect of SCFC loading was studied as to establish the best formulation of the PTSG Biodegradable Hybrid Composite. The composites were fabricated into thin sheets using a hot compression molding machine. The PTSG Biodegradable Hybrid Composite were tested for tensile test, impact test, and flexural test. Then, the environmental properties were determined through soil burying test, weathering test, water absorption test and thickness swelling test. The fracture morphology of the samples was observed under scanning electron microscope (SEM). The increasing of tapioca starch content had significantly increased the degradation, water absorption and swelling thickness of produced composite. The optimum compounding formulation of the fabricated composites was observed at the combination of 90 wt.% of PP, 10 wt.% of TS, 1 wt.% of SCFC and 3 wt.% of glycerol for PTSG Biodegradable Hybrid Composites that have the potential kinetic of degradation at 0.014 %/day of weight reduction which could potentially applied in the real green food packaging industries as one of new candidates for future food packaging materials. In overall, all the listed research objectives were successfully achieved from this preliminary research
