Zusammenfassung: | To provide a laminate that maintains superior barrier performance even after long-term storage in a rolled state, and suppresses deterioration in the barrier performance during processing operation involving heat application.SOLUTION: A laminate has a layer composed of metal or metal oxide (M layer) on one side of a polypropylene resin film. The height of the protruding ridge on the M layer surface, (Spk1), is 10 nm or more and 100 nm or less. A value determined by multiplying the F5 value at 100°C in the direction perpendicular to the primary orientation axis within the film plane by the thickness, (Strength X), is 80 N/m or more and 400 N/m or less. A static friction coefficient when rubbing different surfaces together, μs, is 0.20 or more and 0.80 or less.SELECTED DRAWING: Figure 1
【課題】 本発明は、ロール状態で長期保管した後も優れたバリア性を維持し、かつ、熱がかかる加工工程でのバリア性悪化も抑制できる積層体を提供することを目的とする。【解決手段】 ポリプロピレン系樹脂フィルムの片面に金属又は金属酸化物の層(M層)を有する積層体であって、前記M層表面の突出山部高さ(Spk1)が10nm以上100nm以下であり、主配向軸とフィルム面内で直交する方向における100℃のF5値に厚みを掛けた値(強度X)が80N/m以上400N/m以下であり、かつ異なる面同士を擦過する際の静止摩擦係数μsが0.20以上0.80以下であることを特徴とする、積層体。【選択図】図1 |
