Abstract:
Disclosed is a foam sheet made of a biodegradable resin composition. The biodegradable resin composition contains a wax and/or a polyolefin resin. The biodegradable resin is mainly composed of polylactic acid. Natural candelilla wax or paraffin wax is preferable as the wax. Polyethylene is preferable as the polyolefin resin. Also disclosed are a foam article and a molded container made of such a foam sheet wherein the degree of crystallinity of the biodegradable resin is 10% or more.
