Biopolymer blended films of poly(butylene succinate)/cyclic olefin copolymer with enhanced mechanical strength for packaging applications

The demand for biodegradable materials is on the rise because humanity is now more concerned about a sustainable lifestyle than ever before. In this regard, we present solution casting synthesized novel biopolymer blended films of poly(butylene succinate)/cyclic olefin copolymer (PBS/COC) for packaging applications. These films were characterized by X‐ray diffraction (XRD), Fourier transform infrared microscopy (FTIR), scanning electron microscopy (SEM), universal tensile testing (ASTM D882 standard), and antibacterial Disc diffusion tests using gram‐negative Escherichia coli (E.coli) and gram‐positive Staphylococcus aureus (S.aureus) bacteria. The XRD and FTIR revealed the type of bonding to be physical in‐between the constituent polymers; ensuring the biodegradable nature of their blends, while the thickness of films was found to be
