ABSTRACT
Our study tested the susceptibility of biodegradable films to degradation in non-industrial composting
conditions. The qualitative and quantitative changes in the films studied were shown by the tests of strength,
weight loss, and microscopic images.
After about 9 weeks of composting, many hollows and pits appeared in the surface of the foils studied and their mechanical parameters were significantly decreased, which proved the loss of biodegradable components.
