Title
(EN) POLY(3-HYDROXYBUTYRATE)-BASED RESIN BOTTLE CONTAINER AND METHOD FOR PRODUCING SAME
(FR) RÉCIPIENT DE TYPE BOUTEILLE DE RÉSINE À BASE DE POLY(3-HYDROXYBUTYRATE) ET SON PROCÉDÉ DE PRODUCTION
(JA) ポリ(3-ヒドロキシブチレート)系樹脂ボトル容器及びその製造方法
Abstract
(EN)
A bottle container configured from a poly(3-hydroxybutyrate)-based resin, wherein the bottle container is such that the thickness of a side wall of the bottle container is 0.1-5.0 mm. The difference between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetric analysis of the poly(3-hydroxybutyrate)-based resin is preferably 10°C or greater. In production of the bottle container, there are preferably included: a step in which, after the poly(3-hydroxybutyrate)-based resin is melted in an extruder, the resin is extruded from an annular die into a tube shape; a step in which the resulting tube is clamped by a mold from both sides; and a step in which air is blown into the tube, of which one end is closed, to mold the tube into a bottle shape. Moreover, in production of the bottle container, it is preferable that the temperature of the annular die is set to a temperature between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetric analysis of the poly(3-hydroxybutyrate)-based resin.

L'invention concerne un récipient de type bouteille configuré à partir d'une résine à base de poly(3-hydroxybutyrate), le récipient de type bouteille étant tel que l'épaisseur d'une paroi latérale du récipient de type bouteille est de 0,1 à 5,0 mm. La différence entre la température de pic de point de fusion et la température d'extrémité de pic de point de fusion dans l'analyse calorimétrique différentielle de la résine à base de poly(3-hydroxybutyrate) est de préférence de 10 °C ou plus. Lors de la production du récipient de type bouteille, figurent de préférence : une étape dans laquelle, après que la résine à base de poly(3-hydroxybutyrate) est fondue dans une extrudeuse, la résine est extrudée d'une matrice annulaire en une forme de tube ; une étape dans laquelle le tube résultant est serré par un moule à partir des deux côtés ; et une étape dans laquelle de l'air est soufflé dans le tube, dont une extrémité est fermée, pour mouler le tube en une forme de bouteille. De plus, lors de la production du récipient de type bouteille, il est préférable que la température de la matrice annulaire soit réglée à une température entre la température de pic de point de fusion et la température d'extrémité de pic de point de fusion dans l'analyse calorimétrique différentielle de la résine à base de poly(3-hydroxybutyrate).
