摘要： A stretched polyethylene film for lamination, which comprises a polyethylene (A) having a weight average molecular weight (Mw) as measured by gel permeation chromatography of from 70,000 to 250,000, a proportion of fractions with a molecular weight of 10,000 or less of 8 wt % or less, and a density as measured in accordance with JIS K6922-1 (1997) of from 945 to 980 kg/m3, and has at least one peak in a range of 135° C. or higher in an endothermic curve as measured by differential scanning calorimetry, the film having high recyclability and excellent in heat resistance.
