To provide a stretched polyethylene film that does not rupture even at a high stretching ratio and has high strength.SOLUTION: A stretched polyethylene film is composed of a polyethylene resin composition containing polyethylene and petroleum resin. The stretched polyethylene film is a uniaxially stretched film or biaxially stretched film, and a surface ratio of multiplied stretching ratios is equal to or higher than three.SELECTED DRAWING: None 【課題】高い延伸倍率としても破断することがなく、高強度である延伸ポリエチレンフィルムを提供する。【解決手段】ポリエチレン及び石油樹脂を含有するポリエチレン系樹脂組成物からなり、一軸延伸フィルム又は二軸延伸フィルムであり、延伸倍率の面倍率が３倍以上である、延伸ポリエチレンフィルム。【選択図】なし
