| Abstract | The single use packaging is widely used in various products; ranging from food to non-food contact, fromcommodity to specialty purposes. Most of these materials are derived from non-renewable fossil resources. In asustainable manner, it needs to be recyclable or compostable. Good mechanical properties together withbiodegradability can make the product more recyclable. In this study, the elasticity for films consisting ofpolybutylene adipate-co-terephthalate (PBAT) blended with polylactic acid (PLA) (10, and 20 %wt), additive andreactive agents were evaluated. The blends were prepared via a twin-screw extruder. The film specimens wereprepared by cast film extrusion. The films were then stretched with different ratios (1.5, 2 and 2.5 times) by theuniaxial machine. The mechanical properties, elasticities and surface morphology of uniaxially stretched PBATand PBAT blend films were characterized by tensile testing and scanning electron microscope (SEM), respectively.The tensile strength of stretched filmstended to improve while the elongation at break reduced at higher stretchingratios. The surface morphology of stretched films revealed that the degree of orientation was increased after higherstretching ratios. The ability to recover in the plastic deformation region of stretched films was increased at thehigher stretching ratios |
