Experimental samples of biodegradable composite material based on polylactide and wood filler, subjected to thermal modification, were obtained. When studying the samples a change in such properties as the rate of biodegradation and tensile strength was observed. It has been established that the degree of preliminary thermal treatment of wood filler can control the rate of biodegradation in the material, which can be used in the production of biodegradable packaging. Depending on the desired product life cycle, packages with an adjustable decomposition time can be created. It is found that with an increase in the degree of heat treatment of the filler in a composite material with more than 40 % of polylactide the tensile strength decreases, while with a lower binder content thermal modification has a positive effect on the strength. Also, adding the fillers can significantly reduce the cost of composite material.
