POLYLACTIC ACID FILM

摘要

A polylactic acid film having excellent transparency, which can maintain high transparency even when exposed to high temperatures. The polylactic acid film is obtained by melt-extruding a polylactic acid (A) which is obtained by melt-mixing a polylactic acid (B) which is mainly composed of L-lactic acid units and a polylactic acid (C) which is mainly composed of D-lactic acid units at a specific weight ratio.  The polylactic acid film is characterized in that (a) the stereocomplex crystallinity is not less than 90%; (b) the haze is not more than 10%; and (c) the change in haze after a 10-minute heat treatment at 140°C is not more than 5%.
