Abstract
The present contribution reports on the incorporation of agricultural waste materials as organic fillers in a film matrix based on PVA. Starch and fibers, derived from sugarcane, apple and orange waste, were cast from PVA aqueous solutions. Glycerol and urea were added as plasticizing agents and resulted effective in obtaining flexible films. Addition of cornstarch resulted in only modest loss of mechanical properties of the films, but reduced the cost of final productrs. To improve water resistance and film cohesiveness, hexamethoxymethylmelamine was added as a crosslinking agent and its effect on the mechanical properties, water resistance and biodegradation (mineralization) rate was assessed. Crosslinked films displayed improved resistance to moisture uptake and degraded slowly in soil.
