Abstract
Description
本発明の薄膜は、ポリウレタン層の層(A)を含むことを特徴とする。ポリウレタン層(A)は、全薄膜の酸素不透過特性と水蒸気不透過特性とを明らかに改善する強い拡散抑制作用を有する。また、層(A)により、特に金属及び金属酸化物を備える本発明の薄膜の耐久性のある被覆が可能になる。
ポリウレタンと共有結合を形成する官能基を有する重合体を含む層(B)(接着層)により、ポリウレタン層(A)薄膜への結合力を改善することができる。好適な重合体は、ポリエチレンである。他の重合体を使用する層(B)は、別途ポリエチレンを配合しなければならない。層(B)は、層(B)の全質量に対し、好ましくは少なくとも50重量%、特に好ましくは少なくとも70重量%、最適には少なくとも90重量%ポリエチレンを含有する。層(B)内のポリエチレンの官能基は、接着剤となる。層(B)の官能基がなく又は不十分量のとき、層(A)は、層(B)から剥離し易く、多層の薄膜構造は、不安定になる。層(B)内のポリエチレンは、層(B)が含有する官能基を有する単一の重合体が好ましい。層(B)中にポリエチレンを配合すると、層(B)、層(C)及び層(D)の処理に類似の特性を生ずる。ポリエチレンは、高密度ポリエチレン、低密度ポリエチレン、線状低密度ポリエチレン並びにそれらの共重合体及びブロック共重合体からなる群から選択される重合体であるが、前記の通り、ポリプロピレン(PP)とポリフェニレンエーテル(PPE)で構成される共重合体を採用できよう。これらの中で、線状低密度ポリエチレンが最も好ましい。
層(C)は、特に本発明の薄膜の機械的特性に決定的に重要な主層(基層又は支持層とも称する)である。層(C)の二軸配向性と層厚は、層(C)の不透過特性と光学特性に顕著に寄与する。
層(A)を有する薄膜の底面に、有効な表面性質、特に十分な表面粗度を与える層(D)は、本発明の薄膜をロールで搬送し、ロールから高速で繰り出すのに役立つ。層(D)は、ポリエチレン薄膜の通常の「表面薄層」を形成する。好適な層(D)は、ポリエチレン同種重合体を含有するが、ポリエチレン共重合体も含有してもよい。
・前記組成の層(B)〜層(D)を備えかつ層(B)と層(D)を外側層とする薄膜を縦方向に一軸で伸張する工程と、

・各重合体を溶融する工程と、
・層(B)と層(D)を薄膜の外側層として、溶融した重合体を金型スリットから押し出して、層(B)、層(C)及び層(D)に対応する少なくとも3層を備える薄膜を形成する工程と、
・得られた薄膜を冷却ロール上で冷却して、層(B)、層(C)及び層(D)を備える薄膜を形成する工程と、
・形成した薄膜を縦方向に延伸する工程と、
・少なくともポリウレタンとナノ粒子を含む流体分散系塗料を層(B)上に塗布して、層(B)上に均一な層を形成する工程と、
・層(B)上の流体分散系塗料を加熱により乾燥して、層(A)を形成する工程と、
・層(A)を形成した薄膜を横方向に延伸して、二軸配向薄膜を製造する工程。
