PROBLEM TO BE SOLVED: To provide a resin composition and its molded product, the main ingredient of which is a polyglycolic acid type aliphatic polyester resin, and the composition having an excellent biodegradable property which has not been known before, together with softness, processability, practical strengths, and barrier property when the composition is subjected to process for making thin-wall product. SOLUTION: The glycolic acid type resin composition and its molded product, in which the resin composition (C) contains 0.5 to 30% by weight of an additive (B) to the resin (A) of which the main ingredient is the polyglycolic acid type aliphatic polyester resin, having the crystal melting point of 110 to 250 deg.C, the resin composition is characterized by using a glycerin triester of fatty acid as the main ingredient of the additive (B), wherein the fatty acids, which constitute three ester groups, has the total number of carbon atoms of 9 or less. |
