Elongations at break values obtained by tensile tests were
significantly different (p < 0.05) to those determined by quasi-
static assays, being around 60 and 17%, respectively (Table 1).
Elongation at break values corresponding to the different studied
formulations, were not significantly different (p > 0.05) among
them (Table 1). The fact that film ductility is kept almost constant
despite talc incorporation could be mainly associated to different
contributions related to talc surfaces and particle orientation. On
one side, few accessible hydroxyl groups on talc edge surface lead
