Abstract
There are disclosed a biodegradable resin composition including a starch (a1), a biodegradable resin (a2) other than a polylactic acid-based polymer and a non-crystalline polylactic acid-based polymer (b), a mass ratio of the starch (a1) to the biodegradable resin (a2) other than a polylactic acid-based polymer (a1/a2) being from 20/80 to 50/50, and a mass ratio of a sum of the components other than the polymer (b) to the polymer (b) (sum of components other than polymer (b)/polymer (b)) being from 95/5 to 50/50, and a biodegradable film using the biodegradable resin composition.
