Abstract – The huge amount of synthetic plastics are used in the packaging area, especially in food packaging, because there have great effects in the environmental and alternative, more ecologic materials are being required. Poly-lactic acid (PLA) is one of the most significant biodegradable thermoplastic polymers. It is compostable and made it from renewable sources. The mechanical and optical property of PLA is very similar to the Polyethylene, but is more fragile, less heat-resistant and offer low resistance to oxygen permeation. In this work, two commercial PLA foils and one commercial PET foil properties were examined. The correlations between the mechanical, thermal and barrier properties were analyzed. From these measurements we can understand the PLA is a usable for packing applications, especially in the sweet manufacturing. Films were studied by tensile testing, differential scanning calorimetry and thermally simulated discharge analysis.
Keywords— PET, PLA, stretching, mechanical properties, TSD, DSC, crystal structure.
