Title
(EN) RESIN FILM
(FR) FILM DE RÉSINE
(JA) 樹脂フィルム
Abstract
(EN) This resin film contains a poly(3-hydroxyalkanoate)-based resin component. The tensile elastic modulus of the resin film is 500-2000 MPa. The swelling degree of the resin film measured after being immersed in methyl ethyl ketone for 2 hours is 1-5. The poly(3-hydroxyalkanoate)-based resin component is preferably a mixture of at least two types of poly(3-hydroxyalkanoate)-based resins that are different from each other in terms of the types of constituent monomers and/or the content ratio of the constituent monomers.
(FR) Film de résine contenant un composant de résine à base de poly(3-hydroxyalcanoate). Le module d'élasticité en traction du film de résine varie de 500 à 2 000 MPa. Le degré de dilatation du film de résine, comme mesuré après immersion dans de la méthyléthylcétone pendant 2 heures, varie de 1 à 5. Le composant de résine à base de poly(3-hydroxyalcanoate) est de préférence constitué d'un mélange d'au moins deux types de résines à base de poly(3-hydroxyalcanoate) qui sont différentes entre elles en termes de types de monomères constitutifs et/ou de proportions des monomères constitutifs.
(JA) ポリ(3-ヒドロキシアルカノエート)系樹脂成分を含有する樹脂フィルム。前記樹脂フィルムの引張弾性率は500MPa以上2000MPa以下である。前記樹脂フィルムをメチルエチルケトンに2時間浸漬して測定した膨潤度は1以上5以下である。前記ポリ(3-ヒドロキシアルカノエート)系樹脂成分は、構成モノマーの種類及び/又は構成モノマーの含有割合が互いに異なる少なくとも2種類のポリ(3-ヒドロキシアルカノエート)系樹脂の混合物であることが好ましい。
