the importance of the crystallinity on polymers blends,
indicating that stable values in the melting point can be
reached for higher quantities of PLA in PET/PLA amorphous
blends produce from casting solution [46]. However, in our
study miscible phases are only obtained with amounts
under 15 wt-% using semi-crystalline biopolymer (PLA).
The endothermic peak observed at 126 C for commercial
PET is missed in the DSC spectra of blends extruded at
260 C, corroborating the presence of small quantities of
additives.
