PURPOSE:To provide filling cushioning material good in filling operation efficiency, excellent in content shift preventing function after use and quick to fill by forming the filling cushioning material of the starch or modified one which, when buried in ground for disposal after use, is putrefied to go out of existence in course of time or when incinerated for disposal, is low in heat generation and free from pollution. CONSTITUTION:The filling cushioning material consists of a foaming molding 1 made from starch or modified one and having a bent main part 1a and from one to several hook-like branched parts 1b extending therefrom in a splitting open form. The filling cushioning material is produced by an extrusion foaming process wherein the starch or modified one mixed in a prescribed proportion and the foaming material consisting of water and foaming agent are molded by an extruding machine under prescribed conditions.
