This study investigates the degradation behavior of gelatin-based films plasticized with varying concentrations of glycerol (12.5–75.0%) when buried in five distinct soil types - coniferous forest, deciduous forest, cinnamon, black “smolnik”, and light sandy soil. Film samples were incubated under both ambient and UV-irradiated conditions for a period of 12 weeks to simulate natural environmental exposure. Soil pH and bulk density were measured and found to influence biodegradation rates. Visual inspection revealed progressive disintegration of the films, with faster degradation in organic-rich soils and under UV exposure. The results demonstrate that both the formulation of gelatin films and the surrounding environmental conditions - particularly soil type and UV irradiation - play crucial roles in determining the rate of degradation.
