Patent ID: 8729165

Claim:
A film or sheet composed of a resin composition comprising: a poly lactic acid (A); an acidic functional group-modified olefinic polymer (B) including an acidic functional group and having an acid value of 10 to 70 mg KOH/g and a weight average molecular weight of 10,000 to 80,000; a tetrafluoroethylene polymer (C); and an aromatic phosphoric acid ester-containing flame retardant (D) including a compound of General Formula (I), the aromatic phosphoric acid ester-containing flame retardant (D) being included in an amount of 15 to 55 parts by weight based on 100 parts by weight of the poly lactic acid (A), where each of n 1 pieces of X 1 s, n 2 pieces of X 2 s, and n 3 pieces of X 3 s is independently an alkyl group having 1 to 14 carbon atoms, an aryl group having 6 to 18 carbon atoms, an oxyalkyl group having 1 to 8 carbon atoms, or an oxyaryl group having 6 to 18 carbon atoms, and each of n 1 ,n 2 , and n 3 is independently an integer of 0 to 4; wherein the tetrafluoroethylene polymer (C) is included in an amount of 0.5 to 15.0 parts by weight based on 100 parts by weight of the poly lactic acid (A); and the acidic functional group-modified olefinic polymer (B) is included in an amount of 0.1 to 10.0 parts by weight based on 100 parts by weight of the poly lactic acid (A).
