Abstract:
(EN) This laminate 1 comprises a base material layer 11 and a sealant layer 15. The sealant layer 15 comprises: a first layer 15a including a cyclic olefin-based resin; and a second layer 15b interposed between the base material layer 11 and the first layer 15a and including a low-density polyethylene resin. The ratio between the thickness of the first layer 15a and the thickness of the second layer 15b is within the range 1:2–5:1. The low-density polyethylene resin has a melt flow rate (MFR) within the range of 3.6–13.0 g/10 mins, at a temperature of 190°C and a load of 21.168 N. The low-density polyethylene resin has a density within the range of 0.915–0.925 g/cm3. The thickness of the first and second layers is at least 5 µm, respectively, and the thickness of the second layer is no more than 25 µm.
(FR) L’invention concerne un stratifié (1) comprenant une couche de matériau de base (11) et une couche d'étanchéité (15). La couche d'étanchéité (15) comprend : une première couche (15a) comprenant une résine à base d'oléfine cyclique ; et une seconde couche (15b) interposée entre la couche de matériau de base (11) et la première couche (15a) et comprenant une résine polyéthylène basse densité. Le rapport entre l'épaisseur de la première couche (15a) et l'épaisseur de la seconde couche (15b) est compris dans la plage de 1:2 à 5:1. La résine polyéthylène basse densité a un indice de fluidité (MFR) compris dans la plage de 3,6 à 13,0 g/10 min, à une température de 190 °C et sous une charge de 21,168 N. La résine polyéthylène basse densité a une densité comprise dans la plage de 0,915 à 0,925 g/cm3. L'épaisseur des première et seconde couches est d'au moins 5 µm, respectivement, et l'épaisseur de la seconde couche n'est pas supérieure à 25 µm.
(JA) 本発明の積層体1は、基材層11とシーラント層15とを具備し、前記シーラント層15は、環状オレフィン系樹脂を含む第1層15aと、前記基材層11と前記第1層15aとの間に介在し、低密度ポリエチレン樹脂を含む第2層15bとを備え、前記第1層15aの厚さと前記第2層15bの厚さとの比は1:2乃至5:1の範囲内にあり、前記低密度ポリエチレン樹脂は、温度が190℃であり、荷重が21.168Nにおけるメルトフローレート(MFR)が3.6g/10分乃至13.0g/10分の範囲内にあり、前記低密度ポリエチレン樹脂は、密度が0.915g/cm乃至0.925g/cmの範囲内にあり、前記第1及び前記第2層の各々の厚さは5μm以上であり、前記第2層の厚さは25μm以下である。
