Abstract
Description
密度は、ASTM D792に従って決定される。
「メルトインデックス」は、「I2」とも称され、ASTM D1238に従って決定される(190℃、2.16kg)。
2%割線係数は、ASTM D882に従って決定される。
エルメンドルフ引裂度は、ASTM D−1922に従って決定される。
光沢度は、ASTM D−2457に従って45°の角度で決定される。
得られたフィルムのヘイズは、全ヘイズ(すなわち、内部ヘイズ及び外部ヘイズ)を指し、ASTM D1003に従って決定される。
透明度は、ASTM D1746に従って決定される。
摩擦係数(COF)は、D1894に従って測定される。
粘着力は、D5458に従って測定される。
最も広義には、本発明は、少なくとも以下の層を含むフィルムである:
a.0.94g/cm3を超える密度及び2g/10分以下のメルトインデックスを有するポリエチレンを含む第1の層と、
b.0.5を超える摩擦係数(COF)及び20グラムを超える粘着力を有するポリエチレンを含む第2の層と、を含み、
第2の層は、フィルムの外層である。
