  Different food packaging materials (LDPE, HDPEcolorless, PET and LDPEblue) were packaged with dates, and irradiated with γ-rays at 0.0, 1.0, 3.0 and 5.0 kGy. Physical, chemical analysis of Polyethylene low density LDPEblue layer and colorless–were used. Besides studying the changes of stored dates quality, which extend to nine months under room temperature (23-25°C, 70-75% RH%) and freezing (-3°C), no significant effects were observed in LDPE, as in the permeability of oxygen, carbon dioxide transmission rate and water vapor, or migration tests up to 20.0 kGy; whereas the differences were significant in the mechanical characters. Detection of free radicals using Electron Spin Resonance (ESR) proved presence of free radicals at high dose (20.0 kGy), then disappeared after three weeks. GC-MS analysis of polymers showed produce 18 compounds after irradiation processes.. View More»
