Abstract
The effects of absorption solvents into poly(ethylene terephtalete) (PET) films, which are used as food packaging materials, was investigated by DSC, SEM and mechanical methods at various temperatures (5, 25 and 40 °C) and for different periods (1–8 weeks), respectively. Due to the interaction of PET films with solvents, there had been serious deformation on the surface morphology of PET films. Plasticizer effects occurrence, because of absorption of solvents, caused weakening of mechanical properties of PET films. As a result, there had been a 42.88 % and 39.20 % decrease in stress at break at 5 °C for 8 weeks, respectively.
