To include poly lactide resin and the plastic medicine, the plastic medicine, possessing the next chemical formula, In formula, R, being the same, even when it is possible to differ, at least one R, is the branching alkyl group which possesses the carbon chain length of C or more, R, the constituent which is the H or acyl basis. With another feature, as for this invention, the manner which offers the hypocrystalline poly lactide film is offered, this manner includes the process which offers the poly lactide resin and poly lactide constituent which includes the nucleating agent and the aforementioned plastic medicine. It pushes out the constituent, forms, as the melting sheet and the melting sheet next, crystallizes poly lactide and in order for the film to offer, is cooled.ポリラクチド樹脂と可塑剤を含み、可塑剤が、次の化学式を有し、式中、Rが、同じでも異なってもよく、少なくとも1つのRが、C5以上の炭素鎖長を有する分枝アルキル基であり、R’が、H又はアシル基である組成物。別の態様では、本発明は、半晶質ポリラクチドフィルムを提供する方法を提供し、この方法は、ポリラクチド樹脂、成核剤及び前述の可塑剤を含むポリラクチド組成物を提供する工程を含む。組成物は、溶融シートとして押し出し成形され、溶融シートは次に、ポリラクチドを結晶化しフィルムが提供するように冷却される。
