The development of new materials environmentally friendly has become an important market niche for the food industry. The agro-industrial wastes and by-products can be an alternative for the production of biodegradable food packaging. The work aimed to produce biodegradable plastic film extruded with antioxidant and anti- bacterial properties by the joining of cassava starch and Brazilian propolis by-product (BPB). The volatile profile of BPB, Brazilian propolis by-product film (BPBF), and control film (CF) were analyzed by gas chromatography. The mechanical, antioxidant, and antibacterial properties of the films were also assessed. Eighty-seven volatile compounds were detected with aldehydes and terpenoids predominating in the samples. The major terpenoid detected in the samples was the 2-pinen-10-ol followed by α-copaene. Benzaldehyde and benzenepropanoic acid ethyl ester were the major aldehyde and ester classes present in the films. The BPBF exhibited promising me- chanical properties showing the highest Elasticity modulus (11.96 Mpa) and excellent antioxidant (8.45 mmol Trolox equivalent/g) and antibacterial (12.5 mg/mL against Staphylococcus aureus and Salmonella Typhimurium) activities. The valorization of agro-industrial by-products following the current trends to environmental care can be a sustainable alternative for the development of a plastic into which the propolis by-product is incorporated in biodegradable packaging.
