Abstract: To improve the polarity of polypropylene (PP) packaging materials, Glycidyl methacrylate and Styrene were applied as co-monomer and grafted onto polypropylene molecules by radiation method. The properties of grafted PP films were characterized by differential scanning calorimeter (DSC), contact angle instrument and mechanical measurement. The results showed that the polarity, printability, lamination performance and thermal stability of PP film increased after grafting which demonstrates that grafting by radiation is an effective way to broaden the application of ordinary PP materials.
