A greener route for efficient extraction of chemically modified cellulose (CMC) from rice husk has been demonstrates. The extracted CMC is solution blended with polyvinyl alcohol (PVA) under optimized conditions to prepare CMC blended polyvinyl alcohol (CMC-b-PVA) packaging film. Further, the developed film has been characterized by Fourier transform infrared spectrophotometer, shore D, optical microscope, universal testing machine and soil burial test. The obtained results disclose the significant improvements in the mechanical properties by 1.49 times and reduced water vapor transmission rate by 33.33 % than PVA film due to reinforcement effect of CMC in PVA matrix. Furthermore, a heat sealed packet from the developed CMC-b-PVA film has been developed, which exhibits the comparable properties to commercially used flexible polyvinyl chloride films in packaging of edible packets along with optimized water barrier and biodegradable nature.

稻壳纤维素与聚乙烯醇共混热封包装膜的制备及表征

已经展示了一种从稻壳中有效提取化学改性纤维素 (CMC) 的绿色途径。提取的CMC在优化条件下与聚乙烯醇(PVA)溶液共混制备CMC共混聚乙烯醇(CMC-b-PVA)包装膜。此外，开发的薄膜已通过傅里叶变换红外分光光度计、肖氏D、光学显微镜、万能试验机和土埋试验进行表征。所得结果表明，由于CMC在PVA基体中的增强作用，与PVA薄膜相比，机械性能显着提高了1.49倍，水蒸气透过率降低了33.33%。此外，已开发出由开发的 CMC-b-PVA 薄膜制成的热封包，
