射出成形体とその製造方法、並びに、射出成形体に用いられるペレット

Injection-molded object, process for producing the same, and pellet for use for injection-molded object

Abstract

PROBLEM TO BE SOLVED: To provide an injection-molded object which comprises plant-derived materials as major components and has heat resistance and a high rate of crystallization. SOLUTION: The injection-molded object is obtained from a resin composition which comprises (A) a lactic acid resin and (B) natural fibers comprising 40 to 60% by mass cellulose and 10 to 30% by mass lignin, wherein the proportion of the lactic acid resin (A) to the natural fibers (B) is from 99/1 to 70/30 by mass and the lactic acid resin (A) has an (L-lactic acid):(D-lactic acid) ratio of from 100/0 to 97/3 or from 0/100 to 3/97.
