摘要
Low price of potato starch as a wide range of sources of biodegradable packaging film substrate, glycerol as a plasticizer, polyvinyl alcohol as a film-forming agent, potato starch-based biodegradable packaging films were prepared by solution casting. Tests were run on potato starch-based biodegradable packaging films to determine mechanical properties, transparency, and color evaluation. It was observed that the increase of the glycerol content in the films increased the macromolecular mobility, and the potato starch films became less stiff and more flexible. Meanwhile, the transparency was decreased obviously.
