(EN) POLYLACTIDE SHEET AND MANUFACTURING METHOD THEREFOR
(FR) FEUILLE DE POLYLACTIDE ET SON PROCÉDÉ DE FABRICATION
(JA) ポリ乳酸系シート及びその製造方法
要約
(EN)
The purpose of the present invention is to obtain a polylactide sheet of excellent transparency and heat resistance and with excellent high temperature moldability. This polylactide sheet has polylactide as the main component and is characterized in that heat shrinkage at 160°C is 0% - 30% and the degree of crystallinity is 1% - 30%.
(FR)
Le problème décrit par la présente invention est d'obtenir une feuille de polylactide présentant une transparence et une résistance à la chaleur excellentes, ainsi qu'une excellente aptitude au moulage à haute température. La solution selon l'invention consiste en une feuille de polylactide qui possède du polylactide en tant que constituant principal et qui est caractérisée en ce que son retrait thermique à 160 °C est compris entre 0 % et 30 % et son taux de cristallinité est compris entre 1 % et 30 %.
(JA)
 本発明の目的は、透明性、耐熱性に優れ、高温成形性に優れたポリ乳酸系シートを得ることである。 本発明のポリ乳酸系シートは、ポリ乳酸を主体とするシートであって、160℃における熱収縮率が0%~30%であり、結晶化度が1%~30%であることを特徴とする。
