To tackle the persistent global issue of non‐biodegradable petro‐plastics, this study undertook the challenge of developing environmentally sustainable and active packaging alternatives. The approach involved preparing composite films by blending poly(hydroxybutyrate) (PHB) and poly(lactic acid) (PLA) while integrating olive oil and zinc oxide to augment their effectiveness. The films were fabricated by mixing different concentrations of ZnO (ranging from 0.5 – 2.5%) and 10% olive oil into the PHB/PLA (70/30) matrix using solvent‐casting. A comprehensive analysis was conducted to assess the properties of the prepared films, including Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Thermogravimetric analysis (TGA), X‐ray diffraction (XRD), Mechanical testing, water vapor permeability, and UV‐blocking properties. Among the tested samples, the film containing 1.5% ZnO (referred to as PPOZ1.5) displayed the highest tensile strength at 30.8 MPa along with improved water vapor permeability. Consequently, PPOZ1.5 film was selected for further investigations which included DPPH radical scavenging activity, and antimicrobial potential. PPOZ1.5 film exhibited exceptional antioxidant activity (>65%) and demonstrated significant antimicrobial efficacy against Escherichia coli, Staphylococcus aureus, and Aspergillus niger. Moreover, when utilized to package bread samples, PPOZ1.5 film effectively inhibited microbial growth, ensuring food safety for an extended storage period of more than 12 days, ultimately contributing to the preservation and safety of packaged bakery products.This article is protected by copyright.

“…Zinc sulfide (ZnS) is an important semiconductor material with a wide band gap energy of 3.77 eV and it stabilizes as a cubic (zinc blende) structure. − It exhibits high photocatalytic activity, has less toxic effects, and has negative conduction band edge potential. High photocatalytic performance might be achieved by the ZnS nanostructure for photoreducing halogenated benzene to its dehalogenation form, splitting water to generate H 2 , and photoreducing CO 2 . − The negative aspects of ZnS for photocatalytic applications, however, include its lower ability to transmit the photoinduced carrier, broadband gap energy, and less antibacterial activity.…”

Synthetic polymer-based packing films, despite their many advantages, have posed a great threat to the environment and human health. In this work, we aimed to prepare a chitson/agar-based film incorporated with ZnS nanoparticles and Co-MOF. The prepared composite films were characterized using various instrumental techniques. The addition of ZnS nanoparticles acts as an antibacterial agent as well as a semiconductor for dye degradation. The incorporation of Co-MOF enhances the thermal stability, UV-barrier property, and mechanical and antibacterial activities of prepared films. In addition, the prepared films have superior biodegradation properties. Sliced carrot pieces packed in these composite films remain fresh for up to 7 days at room temperature. Moreover, the prepared films have photocatalytic activity against brilliant blue dye with a degradation efficiency of 88.8%.
