Abstract
The objective of the paper was to examine the effect of changes of properties of biodegradable materials produced from thermoplastic starch (TPS) with pine wood dust (PWD) additive. Native potato starch, vegetable glycerine and pine wood dust (by-product of pine pellet production) were used for material production. The tests covered selected mechanical properties, i.e.: tensile strength, punching shear strength and Young's modulus. They also included the description of strength parameters changes in an environment with increased humidity for 5 days. The obtained results support application of cellulose additives to strengthen the structure of biodegradable materials.
