Environmentally friendly packaging materials based on thermoplastic starch

Low density polyethylene (LDPE) is extensively used as a packaging material and as such have a short service life but on the other hand has a long environmental persistence. The alternative to reducing the impact of LDPE as packaging materials on the environment is to blend them with carbohydrate based polymers, like starch. So, the focus of this investigation is to prepare the bio-based blends of LDPE and thermoplastic starch (TPS) that contain different amount of TPS by using a Brabender kneading chamber. Due to incompatibility of LDPE/TPS blends, a styrene– ethylene/butylene– styrene block copolymer grafted with maleic anhydride (SEBS-g-MA) containing 2 mol % anhydride groups was added as a compatibilizer. The effect of the biodegradable, hydrophilic TPS, its content and the incorporation of the compatibilizer on the properties of LDPE/TPS blends were analysed. The characterization was performed by means of thermogravimetric analysis (TG), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and water absorption (WA). Based on the results of the morphological structure, a good dispersion of the TPS phase in LDPE matrix was obtained with the incorporation of compatibilizer which were resulted in better thermal and barrier properties of these materials.
