This article examines compositions based on low density polyethylene containing various lignocellulosic fillers–flax shive, sunflower husk, hay, birch leaves, lignosulfonate, and banana skin. The ethylene‐vinyl acetate copolymer is used as a compatibilizing component. The article is aimed at identifying the main factors determining biodegradation rate of the compositions. Thermal resistance and morphology of the fillers, mechanical and structural characteristics of the compositions, and their stability in aqueous media and ground soil were studied. The influence of the filler particle shape on the resistance of the compositions against various effects was shown. It was found that an increase in the length‐to‐diameter ( L / D ) ratio of the filler particles increases strength and water absorption, reduces melting viscosity, and accelerates biodegradation in soil.
