Biodegradable Composite Materials Based on Natural Polymers

Polylactide/starch/polycaprolactone compositions have been created that are promising for the production of biodegradable packaging materials. The influence of the composition of the proposed mixtures on their mechanical properties and ability to decompose both under in vitro conditions in an accelerated mode in water and in the soil of central Russia was studied. It has been shown that a small addition of polycaprolactone improves the polylactide processing and also reduces the fragility of these compositions at starch concentrations of up to 30 wt %.
