Published: March 14, 2025

Biopolymeric films derived from starch are gaining attention due to their potential applications, which primarily attributed availability and biodegradability. Here, we report developing characterizing a biopolymeric film utilizing banana peel waste (BM2). Analytical techniques were employed, including water absorption analysis, determination of soluble matter, UV-visible spectrophotometry, tensile strength assessment, morphological examination using scanning electron microscopy (SEM), thermal analysis through thermogravimetric (TGA). The revealed noteworthy percentage 115.23% 61.75% matter. spectrophotometry results demonstrated light absorbance degree ranging 0.9 720 nm, particularly between 400 1000 nm. However, the mechanical tests indicated relatively low resistance at 0.8 MPa, irregular surface observed in film’s morphology as evidenced by (SEM). Thermal conducted via TGA offered valuable insights into degradation behavior film. findings reveal temperature 160 300 °C, thereby elucidating stability its applications. While limitations evident, properties, presenting specific those that do not necessitate elevated strength. Continued efforts optimizing refining structure promise bolster making it suitable for various
