Biodegradable compounds from regenerable resources for packings


Abstract:
The films obtained through PVOH - starch compounds melt processing, are totally destroyed in nature, due to the starch biodegradability, on one hand, the water solubility of PVOH and the biodegradability of the resulted solution, on the other hand. The paper demonstrated that the utilization of compounds with proper chemical structure make possible the modification of the PVOH and starch morphology and the formation of a new one, in such manner that the resulted PVOH - starch blends have properties different from those of the blends without destructuration additives. Keywords: alcool polivinilic, amidon, compozite biodegradabile, compatibilizare prin încâlcire (“entaglement”)
