Because Polylactide (PLA) is biodegradable and produced from annually renewable resources, It is well known that PLA has been brittleness and rigidity owing to intrinsical dense backbone, from which the limitations of PLA applicability is obsened on manufacturing process. In this study, a specific PLA was melt-mixed with selected plasticizers. such as PEG which is for a plasticizer to use of foods packing materials in order to keep transparency of PLA blends. The biodegradability was measured using enzyme. the PLA matrix on the rheological properties and thermal stability were measured by scanning electron microscopy(SEM), differential scanning calorimetry(DSC). |
