Abstract

Provided are a film or sheet composed of a resin composition that includes 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 a dicarboxylic acid ester-containing plasticizer (D) containing a compound of General Formula (1) and in which the dicarboxylic acid ester-containing plasticizer (D) is included in an amount of 8 parts by weight or more and less than 40 parts by weight based on 100 parts by weight of the poly lactic acid (A), and a method for manufacturing the film or sheet by melt film formation. Each sign in Formula is as described in the specification.
