Full article:

The biodegradable polymer PBAT can form blends with natural and abundant polymers such as starch, resulting in materials suitable to produce packaging that has a reduced environmental impact upon disposal. PVOH and glycerol have shown promise as plasticizers in these blends, improving their mechanical properties and degradation rates. In the present study, through extrusion processes, injection molding, tensile mechanical and impact tests, PBAT/starch polymer blends plasticized separately with PVOH, and glycerol were produced and evaluated. The obtained data support the plasticizing capabilities of PVOH and glycerol, reducing the tensile modulus of the blends by 21 and 54%, respectively.
