Resumo
In this work were developed free films from Surelease®, additives α-GOS (alfa-glucooligosaccharide) and/or Tween® 80 in aqueous solution. It was obtained by Teflon plates casting process. The free films were characterized by thermal analysis (DSC and TGA), infrared spectroscopy (FTIR-ATR) and scanning electron microscopy (SEM). DSC and TG analysis showed that the additives do not influenced in the thermal stability of Surelease® films. SEM analysis observed homogeneous morphological characteristics and phase detachment absence. FTIR-ATR spectra were used to confirm the physical mixture between the components of films.
