Description
まず、図1および図2を参照して、本発明の一実施形態に係る接着フィルム構造体1の構成について説明する。図1は、本実施形態に係る接着フィルム構造体1の概略を説明する模式的な側面図である。
続いて、上述した本実施形態に係る接着フィルム構造体1の製造方法について説明する。なお、以下に示す製造方法は、あくまでも一例であって、本実施形態に係る接着フィルム構造体1の製造方法が下記に限定されるものではない。
続いて、図4を参照して、本実施形態に係る接着フィルム構造体1の接着剤層22を被接着体に仮貼りする工程について説明する。図4は、接着フィルム構造体1の接着剤層22を被接着体に仮貼りする工程を説明する説明図である。
以下に示す方法によって、本実施形態に係る接着フィルム構造体を製造した。
次に、上記にて製造した接着フィルム構造体を用いて、図4にて示した方法にて被接着体への仮貼り工程を行った。具体的には、各接着フィルム構造体のフィルムロールから、0.7Nの引き出しテンションにて接着フィルム構造体を引き出し、接着剤層をハーフカットした後、切断した接着剤層を被接着体に熱圧着した。
接着フィルム構造体に対する評価結果を表1にまとめて示す。なお、表1において、「ハーフカット後のフィルム基材の残膜厚」は、連結テープが貼付された連結領域をハーフカットした際に、ハーフカットにより切断されなかったフィルム基材の膜厚を示す。具体的には、「ハーフカット後のフィルム基材の残膜厚」は、ハーフカット時のスリット刃と裏面との距離44μmから、連結テープ全体の膜厚Ttを減算した値である(ただし、負値は0として記載した)。また、「ハーフカット後のフィルム基材の残存率」は、「ハーフカット後のフィルム基材の残膜厚」をフィルム基材の膜厚Fbで除算した結果を百分率で表したものである。
