This study represents an alternative method for recycling of a
frequently used food packaging kind, which contains PE, Aluminum
and PET, by separation and recycling of PET in multilayer films. The
product of depolymerization of PET, by supercritical ethanol, was
characterized by means of FTIR, 1H NMR, 13C NMR spectroscopies
and thermo-analysis (DSC and TGA).
