To provide a vinylidene chloride-based resin wrap film which exhibits good adhesion and drawability in a use environment with an ordinary thermal history, and good drawability even under a long-term preservation or high-temperature exposure condition, while providing a soft hand feel without stickiness and realizing an appropriate use feeling.SOLUTION: The vinylidene chloride-based resin wrap film is a wrap film containing a vinylidene chloride-based resin, where after a roll of the wrap film is stored at 60°C for 3 weeks the low-temperature endothermic peak temperature, evaluated using a differential scanning calorimeter (DSC), of the oligomer bled out to a surface of the wrap film is 35-50°C.SELECTED DRAWING: None 【課題】本発明は、通常熱履歴による使用環境下での良好な密着性や引出性を発現するとともに、長期間保管または高温暴露時にも引出性に優れ、さらには、べたつきのないしなやかな手触り感をもたらし、好適な使用感を実現する塩化ビニリデン系樹脂ラップフィルムを提供することを目的とする。【解決手段】本発明は、塩化ビニリデン系樹脂を含有するラップフィルムであり、該ラップフィルムの巻回体を６０℃で３週間保管したのちのラップフィルム表面へのブリードアウトしたオリゴマーの、示差走査熱量計（ＤＳＣ）にて評価した低温側吸熱ピーク温度が３５〜５０℃である塩化ビニリデン系樹脂ラップフィルムである。【選択図】なし
