Summary:To provide a plastic film winding roll capable of suppressing generation of a winding mark or an indentation generated for each winding due to a step made by a thickness of a film and an adhesive tape, on a plastic film which is required to have high smoothness and no indentation nor wrinkle.SOLUTION: In a roll 1, a plastic film 4 having a gas barrier layer is wound on a tubular type core 2. A resin foam layer 3 is provided on a core outer peripheral surface, and an end part 5 of winding start of the plastic film is fixed to the resin foam layer with an adhesive tape 6 whose thickness is 10-150 μm.SELECTED DRAWING: Figure 1 【課題】高い平滑性、圧痕やシワが無いことが要求されるプラスチックフィルムに、フィルムの厚みや粘着テープによる段差により周回ごとに発生する巻き跡、圧痕の発生を抑制できるプラスチックフィルム巻取りロールを提供する。【解決手段】円筒形のコア２に、ガスバリア層を有するプラスチックフィルム４を巻き付けたロール１であって、コア外周面に樹脂発泡体層３が設けられ、プラスチックフィルムの巻き始めの端部５が、厚さが１０〜１５０μｍの粘着テープ６で樹脂発泡体層に固定されている。【選択図】図１
