The search for sustainable materials is driven by the depletion of petrochemical resources and the environmentalimpact of plastics across various biomes. In this context, the present study develops eco-friendly films usingbacterial cellulose derived from agro-industrial soursop (Annona muricata L.) wastes (BC-S) in ternary blends (TB)with poly(vinyl alcohol), polyvinylpyrrolidone, and poly(ethylene glycol). This blend showed a total concentrationof 7,0 wt% with 8:1:1 proportion polymeric, respectively. The incorporation of BC-S (1.0, 3.0, and 5.0 %,v/v) resulted in: (ⅰ) the formation of homogeneous single-layer films; (ⅱ) significant enhancement of mechanicalproperties, such as tensile strength (> 25.73 MPa), elongation at break (> 148.60 %), and increase in Young’smodulus (> 3.0 GPa) by 73.9 %; (ⅲ) excellent UV radiation protection, for UV-C (200–280 nm) an increase of7.5 %; (ⅳ) good water vapor barrier properties with a 54.5 % reduction; and (ⅴ) low transmittance and hightransparency (an increase of 59.2 %) compared to the control treatment. The results demonstrate the potential of5 % (v/v) BC-S derived from agro-industrial residues for sustainable applications as a reinforcement agent inbionanocomposites for food packaging. Therefore, it bolsters the concept of upcycling and eco-friendly packagingsolutions.
