Title
(DE) DEKORATIVE MEHRSCHICHTIGE EXTRUSIONSGEBLASENE FLASCHE
(EN) DECORATIVE MULTILAYERED EXTRUSION BLOWING BOTTLE
(FR) BOUTEILLE MULTICOUCHE DÉCORATIVE PRODUITE PAR EXTRUSION SOUFFLAGE
Abstract
(EN) A decorative multilayered extrusion-blow-formed bottle having an inner layer of a polyethylene (A) and a metallic layer of a polyethylene (B) in which a metal pigment having an average thickness of not more than 600 nm is dispersed on the outer side of the inner layer,wherein, if the shear viscosities (Pa·s) of the resin that is forming the layer neighboring the metallic layer on the inner side thereof are denoted by Vand Vas measured at the shear rates 6 sand 30 sthereof at a temperature of 210°C, then the shear viscosities (Pa·s)andof the polyethylene (B) measured at the shear rates 6 sand 30 sthereof at a temperature of 210°C satisfy the following viscosity condition formulas (1) and (2):
(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.
