Abstract
Disclosed is a biaxially stretched polylactic acid multilayer film and the use thereof as packaging film. The gist of the biaxially stretched polylactic acid multilayer film resides in the construction wherein a substrate layer (1) of the biaxially stretched film comprised of polylactic acid (A) has been laminated on at least one surface thereof with a coating layer (II) of an aliphatic polyester composition (D) comprised of 97.about.5% by weight of an aliphatic polyester copolymer (B) having a melting point (Tm) of 80.about.120.degree. C., a crystallizing temperature (Tc) of 35.about.75.degree. C. and a difference of (Tm)-(Tc) within the range of 35.about.55.degree. C. and comprising an aliphatic or alicyclic dicarboxylic acid component (b1), an aliphatic or alicyclic dihydroxyl compound component (b2) and a difunctional aliphatic hydroxycarboxylic acid component (b3) and 3.about.95% by weight of a polylactic acid copolymer (C) containing 7.about.30% by weight of D-lactic acid, a total of the ingredients (B) and (C) being 100% by weight.
