Title
(EN) DECORATIVE MULTILAYERED EXTRUSION BLOWING BOTTLE
(FR) BOUTEILLE MULTICOUCHE DÉCORATIVE PRODUITE PAR EXTRUSION SOUFFLAGE
(JA) 加飾多層押出ブローボトル
Abstract
(EN) A decorative multilayered extrusion blowing bottle provided with an inner layer that is formed from a polyethylene (A) and a metallic layer that is arranged outside the inner layer, has an average thickness of 600 nm or less and comprises a polyethylene (B) and a metal pigment dispersed in the polyethylene (B). The decorative multilayered extrusion blowing bottle is characterized in that, when the shear viscosities (Pa·s) of a resin forming an inner adjacent layer to the metallic layer as measured at shear rates of 6 s-1 and 30 s-1 at a temperature of 210ºC are respectively represented by V6 and V30, the shear viscosities η6 and η30 (Pa·s) of the polyethylene (B) as measured at shear rates of 6 s-1 and 30 s-1 at a temperature of 210ºC meet the following viscosity requirement formulae (1) and (2): (1) η6 ≥ V6 - 2000; and (2) η30 ≥ V30 - 2000.
(FR) La présente invention concerne une bouteille multicouche décorative produite par extrusion soufflage pourvue d'une couche interne qui est formée à partir d'un polyéthylène (A) et d'une couche métallique qui est disposée à l'extérieur de la couche interne, ayant une épaisseur moyenne de 600 nm ou moins et comprenant un polyéthylène (B) et un pigment métallique dispersé dans le polyéthylène (B). La bouteille multicouche décorative produite par extrusion soufflage est caractérisée en ce que, lorsque les viscosités de cisaillement (Pa·s) d'une résine formant une couche adjacente interne à la couche métallique telles que mesurées à des vitesses de cisaillement de 6 s-1 et 30 s-1 à une température de 210 °C sont respectivement représentées par V6 et V30, les viscosités de cisaillement η6 et η30 (Pa·s) du polyéthylène (B) telles que mesurées à des vitesses de cisaillement de 6 s-1 et 30 s-1 à une température de 210 °C satisfont les formules de spécification de viscosité suivantes (1) et (2) : (1) η6 ≥ V6 - 2000 ; et (2) η30 ≥ V30 - 2000.
(JA) ポリエチレン(A)からなる内層と、該内層よりも外側に平均厚みが600nm以下の金属顔料がポリエチレン(B)に分散されているメタリック層が設けられている加飾多層押出ブローボトルにおいて、前記メタリック層の内側隣接層を形成している樹脂について、210℃の温度で測定したときの剪断速度6s-1及び30s-1での剪断粘度(Pa・s)をそれぞれV、V30とした時、前記ポリエチレン(B)について、210℃の温度で測定したときの剪断速度6s-1及び30s-1での剪断粘度(Pa・s)η及びη30は、下記粘度条件式(1)及び(2): η≧V-2000 (1) η30≧V30-2000 (2) を満足することを特徴とする。
