PROBLEM TO BE SOLVED: To provide a protective film for taking out a content such as a reagent for inspection by breaking with a dropper or a pipet which can easily be break with these dropper, pipet, and the like, and yet does not drop film pieces when breaking.SOLUTION: A piercing-easy polyester film 21, an aluminum foil or an aluminum alloy foil 22, and a sealant layer 23 are laminated in this order. Film pieces do not drop when breaking with a dropper, a pipet and the like as the layer constitution contains the piecing-easy polyester film. Furthermore, a content can be taken out by breaking easily with these dropper, pipet and the like since the polyester film is easy to be pierced.SELECTED DRAWING: Figure 2 【課題】スポイトやピペット等で突き破って検査用試薬等の内容物を取り出す保護フィルムであって、これらスポイトやピペット等で容易に突き破ることができて、しかも、突き破った際にフィルム片が落下することのない保護フィルムを提供すること。【解決手段】易突刺性のポリエステルフィルム２１、アルミニウム箔又はアルミ合金の箔２２、シーラント層２３をこの順に積層する。その層構成中に易突刺性のポリエステルフィルムを含んでおり、このため、スポイトやピペット等で突き破ったときにもフィルム片が落下しない。しかも、このポリエステルフィルムは易突刺性であるため、これらスポイトやピペット等で容易に突き破って内容物を取り出すことが可能となる。【選択図】図２
