Other plasticizers such as urea, formamide, combinations of urea and formaldehyde, 125 used with thermoplastic corn starch at different concentrations were also reported. Property evaluation by Ma et al. 125 showed that mixtures of urea (20 wt%) and formamide (10 wt%) plasticized TPS exhibited better thermal stability, water resistance and better mechanical properties than conventional Effects of Plasticizers and Clays on the Physical, Chemical, stirring. The mixture of starch, plasticizer, and nanoclay was stirred constantly for several hours at 70 C allowing the evaporation of the solvent. The suspension was then poured into a polyethylene sheet and kept under vacuum at 40 Cto obtain starch − S1).

Introduction of formaldehyde in the starch–PVA film decreased the film nutrient ions permeability by inter- and intramolecular crosslinking of –OH bond of starch and PVA. Starch-g-poly(vinyl acetate) was reported as a biodegradable carrier material and used for encapsulating urea fertilizer. [ 176 ] Starch Based Bio-Plastics: The Future of Sustainable Starch: The Future of Sustainable Packaging. 1) Starch blends with compostable polymers: Starch based plastics are complex blends of starch with compostable plastics such as PLA, PBAT, PBS, PCL and PHAs. Blending of starch with plastics improves water resistance, processing properties and mechanical properties.
