Claims (1)

  1. ポリマー層の積層体を具備するフィルムであって、前記ポリマー層が層パケットに編成されていて、前記層パケットの各々が、表主面と、裏主面と、前記表主面と前記裏主面との間の少なくとも３つの前記ポリマー層とを有してなる、前記フィルムにおいて、
    前記積層体中の隣接する第１及び第２の層パケットの全ての対について、前記第１の層パケットのポリマー層のうち前記第２の層パケットに接触するポリマー層を最後方のポリマー層とし、前記最後方のポリマー層が接触する前記第１の層パケットのポリマー層を内側ポリマー層とし、前記最後方のポリマー層が接触する前記第２の層パケットのポリマー層を最前方のポリマー層とするとき、前記最後方のポリマー層が、前記内側ポリマー層に対する付着よりも弱く前記最前方のポリマー層に付着しているため、結果として、前記第１の層パケットが、前記最後方のポリマー層と前記最前方のポリマー層との間の境界面に対応する離層表面に沿って前記第２の層パケットから不可逆的に離層する傾向にあり、かつ
    前記ポリマー層の積層体中の前記ポリマー層の全てが互いに共押出し可能なそれぞれのポリマー組成物を有し、前記積層体中の前記ポリマー層の少なくとも幾つかが配向されている、フィルム。
JP2017235802A 2012-08-28 2017-12-08 連続して不可逆的に離層されるべく構成された共押出しポリマーフィルム Pending JP2018083424A (ja)
