Zusammenfassung:	To provide a film using a plant-derived polyethylene-based resin being a renewable resource as a raw material to enable oil-resource saving, as well as being environment-friendly by reducing carbon dioxide output, and also to provide a packaging bag using the film.SOLUTION: A film is a film having a single layer constitution including a polyethylene-based resin composition or a film having a multilayer constitution including at least one layer composed of a polyethylene-based resin composition, and formed through extrusion molding by a T-die method. The polyethylene-based resin composition includes a plant-derived polyethylene-based resin selected from a plant-derived high-density polyethylene or a plant-derived linear low-density polyethylene.SELECTED DRAWING: Figure 3 【課題】再生可能資源である植物由来のポリエチレン系樹脂を原料に用いて、石油資源の節約を可能とすると共に、二酸化炭素の排出量削減による環境にやさしいフィルムおよび該フィルムを用いた包装袋を提供することを目的とする。【解決手段】ポリエチレン系樹脂組成物からなる単層構成のフィルムであるか、または、該ポリエチレン系樹脂組成物からなる層を少なくとも１層含む多層構成のフィルムであって、Ｔダイ法により押出成形されてなり、前記ポリエチレン系樹脂組成物は、植物由来高密度ポリエチレンまたは植物由来直鎖状低密度ポリエチレンから選択される植物由来ポリエチレン系樹脂を含むことを特徴とする、上記フィルムを提供する。【選択図】図３
