FOAMABLE RESIN COMPOSITION AND FOAMED BODY

摘要

A foamable resin composition according to the present invention comprises starch, an aliphatic polyester and water, and wherein 10 to 40 parts by mass of the water and 10 to 80 parts by mass of the aliphatic polyester are included with respect to 100 parts by mass of the starch. The foamable resin composition preferably comprises 3 to 60 parts by mass of a glycerin with respect to 100 parts by mass of the starch. The whole composition of the foamable resin composition is made of a biodegradable raw material, and the molded product of the composition has excellent water resistance and favorable moldability, is free from problems in mechanical characteristics such as strength, and also has a cost advantage.
