Matériaux biodégradables à base d'amidon expansé renforcé de fibres naturelles - Application à l'emballage alimentaire

Abstract : Within the framework of sustainable growth, the use of biodegradable polymers as an alternative to synthetic polymers seems to be the best solution that could resolve waste disposal problems. The aim of this work was to develop a fully biodegradable multilayered composite that can be a good candidate to substitute expanded polystyrene actually used as a food tray in packaging industries. Polycaprolactone was used as external layers. The core was made of potato starch foam reinforced by natural fibres (hemp, cellulose, wheat straw, cotton linter). The influence of nucleating agents in the different formulations was studied. The processing conditions (extrusion, calendering) were optimized. The mechanical properties, as well as the water sensitivity, the microstructure (cell size, wall thickness) and the biodegradability were determined and optimized.
