Abstract This study presents an easily prepared film based on alkaline starch-polyvinyl alcohol hybrid and lignin fiber as an
additive (SPL film). The SPL film was prepared under acidic conditions through a polycondensation reaction of
PVA and a mixture incorporating alkaline starch and lignin fiber from agriculture or forest source. The examination
using scanning electron microscopy (SEM) showed that the surface of SPL film was smooth and the lignin fiber had
good compatibility within the film hybrid. Electrospray ionization mass spectroscopy (ESI-MS) and fourier transform
infrared (FTIR) investigations indicated that alkaline starch and lignin fiber reacted with PVA under acidic conditions… More >
