Abstract
Nowadays, the packaging industry is highly dependent on petroleum products for improved mechanical and thermal properties. Along with that, pollution is created as they are non-biodegradable products. This research work shaped eco-sustainable blown films with the commercially available blend of Poly Butadiene adipate-co-terephthalate (PBAT) & Thermoplastic Starch (TPS), named BF-02. This blend uses mineral fillers like CaCO3 to improve mechanical performance and make it cost-effective without compromising its degradability. Samples were made by using twin screw extruders in higher concentrations of filler, i.e., 30–40%. Then, these pellets were used to make blown films. The sample's performance was tested on mechanical properties like tensile strength, Young’s modulus, and elongation at Break. The BF-02 performed better tensile strength and elongation at break, and the fillers C30 and C40 performed better in Young’s Modulus. Moreover, no noticeable change was observed during UV degradation, as the remaining sample didn’t degrade up to 480 hrs. This is also because of the shading effect of mineral fillers added to the blend. The thermal properties were also studied, but no change or shift was observed due to adding fillers. The biodegradation of the C30 and C40 showed a better soil degradation rate than BF-02.
