Cassava starch-chitosan-sorghum micro-fibrillated cellulose biocomposite wrapping film to prevent COVID-19 outspread

Abstract To prevent virus spreading, the corpse or coffin of COVID-19 patients need to be wrapped in plastic. Low-density polyethylene (LDPE), a crude oil-based wrapping plastic, is difficult decompose nature after use. In this study, biocomposite film was developed from cassava starch and chitosan, with addition sorghum Micro-Fibrillated Cellulose (MFC) by levels 1%, 2%, 3%, 4% 5%. Cassava (raw starch) modified acetic anhydride produce acetylated (acetylated which less hydrophilic thus enhance compounding ability LDPE. The MFC obtained fibers following processes: soda pulping, bleaching fibrillation super grinder. 1% into raw starch-chitosan increased tensile strength modulus elasticity 33% 17%, respectively. On other hand, 2% elongation 38%. Wrapping needs have good so that it can stretched during application. Based on characteristic, candidate for outspread.
