Abstract

主収縮方向である長手方向への収縮性が高く、収縮仕上がり性、ミシン目開封性、溶剤接着性が良好な熱収縮性ポリオレフィン系フィルムを提供する。 本発明のフィルムは、環状のポリオレフィン系樹脂を主成分とするスキン層と非環状のオレフィン系樹脂を主成分とするコア層とが積層されており、主収縮方向が長手方向になっている。そして、フィルム全体の厚みに対するスキン層の厚みの比率、９０℃の温水中で１０秒間処理した場合における長手方向の温湯熱収縮率、７０℃～９０℃の温水中で１０秒間処理した場合における幅方向の温湯熱収縮率、８０℃の温水中で長手方向に１０％収縮させた後の幅方向の直角引裂強度が、それぞれ、所定の範囲となるように調整されている。
