Description 453-459
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.
