Abstract
A starch-based biodegradable composition with excellent mechanical properties and durability, which includes thermoplastic starch, a biodegradable resin, a first compatibilizer, a second compatibilizer, and a lubricant is described. The first compatibilizer is an epoxy compound and the second compatibilizer is a tricarboxylic acid. A biodegradable film manufactured using the composition is also described.
Claims10
A starch-based biodegradable composition comprising:
- thermoplastic starch;
- a biodegradable resin;
- a first compatibilizer;
- a second compatibilizer;
