PROBLEM TO BE SOLVED: To provide a shade film having a high strength and being excellent in a strength balance between the length and the width. SOLUTION: This film is constituted of an ethylene (co)polymer which satisfies the necessary conditions that the density is 0.86-0.97g/cm<3> , the melt flow rate 0.01-100g/10min., the molecular weight distribution (Mw/Mn) 1.5-5.0 and the composition distribution parameter Cb 2.00 or below. In this case, the grain size of a concentric mass constituted of integrated bodies of crystal lamellas of the surface of the film is made 0.5-8μm, the tear strength of the film 20 Kgf/cm or above in the longitudinal (MD) direction and 60 Kgf/cm or above in the lateral (TD) direction and the outer haze of the film 20% or above. |
