Abstract
Provided are a biodegradable resin composition and a biodegradable resin molded article, and the biodegradable resin composition includes (A) a polyolefin-based compound, (B) a biodegradable resin, (C) an aliphatic-aromatic copolyester-based compound, and (D) a modified polyolefin-based compound, wherein (A) the polyolefin-based compound is included in an amount of 7 to 30 wt % with respect to a total of (A) to (D), and a total of (C) the aliphatic-aromatic copolyester-based compound and (D) the modified polyolefin-based compound is included in an amount of 45 to 80 wt % with respect to the total of (A) to (D).
Claims17
A biodegradable resin composition comprising:
- (A) a polyolefin-based compound;
- (B) a biodegradable resin;
- (C) an aliphatic-aromatic copolyester-based compound;
- and
- (D) a modified polyolefin-based compound,
- wherein (A) the polyolefin-based compound is included in an amount of 7 to 30 wt % with respect to a total of (A) to (D), and
- a total of (C) the aliphatic-aromatic copolyester-based compound and (D) the modified polyolefin-based compound is included in an amount of 45 to 80 wt % with respect to the total of (A) to (D).
A method of manufacturing a biodegradable resin molded article, comprising the steps of:
- (1) mixing (A) a polyolefin-based compound, (B) a biodegradable resin, (C) an aliphatic-aromatic copolyester-based compound, and (D) a modified polyolefin-based compound so that (A) the polyolefin-based compound is included in an amount of 7 to 30 wt % with respect to a total of (A) to (D), and a total of (C) the aliphatic-aromatic copolyester-based compound and (D) the modified polyolefin-based compound is included in an amount of 45 to 80 wt % with respect to the total of (A) to (D), and performing melt blending to obtain a biodegradable resin composition;
- and
- (2) molding the biodegradable resin composition.
