Flexible and transparent films from SPI and agar (AG) obtained
from Gelidium sesquipedale (Rhodophyta) were prepared by
thermo-molding method as well as casting (Guerrero et al., 2013;
Tian et al., 2011). It was observed that the casting films possessed
more homogeneous interfaces compared to the molding films,
leading to their superior mechanical properties. Fig. 5 shows the
tensile strength (a) and elongation at break (b) of soy protein/agar
(AG) blend films prepared from solution casting and thermo-
