• A bioplastics film with excellent physical and barrier properties was prepared with Poly(butylene adipate-co-terephthalate) (PBAT), thermoplastic starch (TPS), and poly(propylene carbonate) (PPC). PBAT/TPS/PPC blend films were investigated through rheological measurements, tensile tests, scanning electron microscopy, mechanical dynamic analysis, and barrier properties. The content of PPC controlled the morphology and continuity development of the PBAT/TPS/PPC blend. With an increase in PPC, the TPS demonstrated better dispersion in the system, and the PBAT and PPC became the continuous phase. Compared with PBAT/TPS films, an increase in PPC led to a decrease in the water contact angle of the films, and water vapor permeability, oxygen permeability, and carbon dioxide permeability of PBAT/TPS/PPC films decreased by 53.1%, 74.4%, and 78.9%, respectively. The addition of PPC increased the dispersion of starch in the film and accelerated degradation of the film. PBAT/TPS/PPC films demonstrated good mechanical properties and excellent barrier properties, indicating that they have potential for use as degradable and cost-effective alternatives to traditional plastics in the packaging industry.
