Description
(3)樹脂層(III)
本発明の樹脂層(III)は、ポリエチレン系樹脂(c)20〜80重量%と環状オレフィン系樹脂(d)20〜重量80%からなることを特徴とする。樹脂層(III)を構成するポリエチレン系樹脂(c)と環状オレフィン系樹脂(d)においては、樹脂層(I)を構成する同樹脂について上述した範囲内であれば、同じ樹脂を用いてもよいし、異なる樹脂を用いてもよい。
(3) Resin layer (III)
The resin layer (III) of the present invention is characterized by comprising 20 to 80% by weight of a polyethylene resin ( c ) and 20 to 80% by weight of a cyclic olefin resin ( d ). In the polyethylene resin (c) and the cyclic olefin resin (d) constituting the resin layer (III), the same resin may be used as long as it is within the range described above for the resin constituting the resin layer (I). A different resin may be used.
