Development of polysaccharide based biodegradable packaging materials suitable for radiation sterilization

Abstract

The biodegradable composites are prepared by melt blending method in Poly-lab Rheomix internal mixer from Thermo Electron. The high-density polyethylene (90 wt%) and maleic anhydride grafted polyethylene (10 wt%) are heat melted at 170 °C under the constant rotors speed (60 rpm). After 3 min, maize starch (Gelose 80) 10 parts per hundred (phr), sepiolite, stearic acid (1 phr), Irganox 1010 (0.2 phr) and Irgafos 168 (0.1 phr) are added and mixed for another 15 min. The sepiolite is varied from 2 to 6 phr in these composites. The PE0, PE2, PE4 and PE6 identification codes are used to represent composites containing 0, 2, 4 and 6 phr of sepiolite respectively. The heat pressed sheets are prepared at 170 οC at 200 bar. These sheet are irradiated under electron beam in air at room temperature using UELV-10-10S linear electron beam irradiator (NIIEFA, Russia) at 10 MeV and 1mA using 1 kGy/pass. The samples are subjected to various doses of electron beam irradiation ranging from 25 to 100 kGy. The structural and morphological analysis of developed composites is characterized by Fourier transform infrared spectrophotometer and scanning electron microscope. The thermal properties are investigated using thermo-gravimetric analyzer and differential scanning calorimeter. The  More>>
