Description
より具体的には、本発明は、ポリスチレン及びポリカーボネート等のキャリアテープ用のカバーフィルムで、電子部品を取り出すためにカバーフィルムを剥離する際の剥離強度が連続して所定範囲内で、かつ高速剥離時においても剥離強度の上昇が少なく、剥離の際の振動によって微小な電子部品の飛び出しや、高速剥離時のカバーフィルムの破断、ベーキング処理による部品付着のような、実装工程でのトラブルを起こすことのないカバーフィルムを提供することを課題とする。
他の実施態様では、剥離層(C)は、芳香族ビニル基の含有量が15〜35質量%である芳香族ビニル−共役ジエン共重合体の水素添加樹脂を主成分として含んでなる。また、剥離層(C)及び/又はヒートシール層(D)が導電材を含有する。このような導電材は、一実施態様では、導電性微粒子であり、形状が針状、球状の微粒子の何れか又はこれらの組み合わせからなる。例えば、導電材はカーボンナノ材料である。
