The incorporation of cellulose fibers reinforced mechanically
the films, without reducing their elongation capacity, and reducing
their water vapor permeabilities, mainly when glycerol was used as
plasticizer. On the other hand, preparing edible films from rice flour
is a new alternative of using this raw material, which is sometimes
much cheaper than commercial starches. The results allow
concluding that, despite water vapor permeabilities are controlled
mainly by plasticizer concentration, fibers addition is a good
alternative to increase this barrier property and to prepare more
stable films.
