である。本発明の伸縮性フィルムがこのような構成を有することにより、本発明の効果をより発現させ得るとともに、本発明の伸縮性フィルムは、取り扱い性に優れ得るとともに、耐ブロッキング性に優れ得る。
本発明の伸縮性フィルムを製造する方法としては、本発明の効果を損なわない範囲で、任意の適切な方法を採用し得る。好ましくは、任意の適切な方法で未延伸フィルムを製造した後に、延伸処理することにより得られる。延伸処理は、好ましくは、未延伸フィルムを製造して十分に固化した後に行う。延伸処理の詳細は、前述の通りである。
本発明の伸縮性フィルムは、本発明の効果を有効に利用できる任意の適切な物品に用いることができる。すなわち、本発明の物品は、本発明の伸縮性フィルムを含む。このような物品としては、代表的には、例えば、衛生用品などが挙げられる。このような衛生用品としては、例えば、おむつ(特に、イヤー(耳)部分や、腰周りや脚周りの開口部分の伸縮性部材(ウエストバンドやギャザー)として本発明の伸縮性フィルムが使用されたおむつ)、サポーター、マスクなどが挙げられる。
通気性は、王研式透気度計(sec/100cc)(旭精工株式会社製、商品名:EG01−7−7MR)を用いて測定した。99999sec/100ccを超えるものについては「通気性無し」と判断した。なお、表1において、「フィルムそのまま」とは、作製したフィルムをそのままの状態で通気性の測定を行ったことを意味する。また、表1において、「幅方向に2倍」とは、作製したフィルムを幅方向に2倍伸張した状態で通気性の測定を行ったことを意味する。
アモルファスPP(エクソンモービル社製、商品名:ビスタマックス6202):70重量部、エチレン系エラストマー(三井化学(株)製、タフマーPN−2070):30重量部、炭酸カルシウム:150重量部を、押出機に投入し、Tダイから押し出して、厚みが150μmの未延伸フィルム(1)を製造した。
次に、未延伸フィルム(1)を、流れ方向に3.8倍の倍率で事前延伸し、伸縮性フィルム(1)を得た。
結果を表1に示した。
