<P>PROBLEM TO BE SOLVED: To provide a stretch film including a polyethylene resin excellent in transparency and tear strength. Ž<P>SOLUTION: The stretch film is obtained by T-die extrusion molding of an ethylene-α-olefin copolymer which satisfies all of the following requirements (A)-(E) and is obtained by gas phase polymerization in the presence of a catalyst: (A) the melt flow rate (MFR) is 2-5 g/10 min; (B) the melt flow rate ratio (MFRR) is 20-25; (C) the density (d) is 0.915-0.930 g/cm<SP>3</SP>; (D) the molecular weight distribution (Mw/Mn) is 2.5-4.5; (E) the cold xylene soluble (CXS) fraction (wt.%) is ≤7%.
