摘要：
Effect of additives on properties of PVA/tapioca starch biodegradable films was studied. The additives used in this research were glycerol (GLY), polyethylene glycol (PEG) and glutaraldehyde (GLU). PVA/tapioca starch blend films were prepared by mixing process and casting method. Increased the GLY and PEG level, increased the elongation at break but decreased the tensile strength of PVA/tapioca starch blend film. The addition of plasticizer also increased the biodegradability, water absorption and water vapor transmission of PVA/tapioca starch blend film. However, GLU showed the opposite results.
