摘要： An injection molded article comprising a thin-walled body portion formed from a polymer-based resin derived from cellulose, wherein the thin-walled body portion comprises: i. a gate position; ii. a last fill position; iii. a flow length to wall thickness ratio greater than or equal to 100, wherein the flow length is measured from the gate position to the last fill position; and iv. a wall thickness less than or equal to about 2 mm; and wherein the polymer-based resin has an HDT or at least 95° C., a bio-derived content of at least 20 wt %, and a spiral flow length of at least 3.0 cm, when the polymer-based resin is molded with a spiral flow mold with the conditions of a barrel temperature of 238° C., a melt temperature of 246° C., a molding pressure of 13.8 MPa, a mold thickness of 0.8 mm, and a mold width of 12.7 mm.
