PROBLEM TO BE SOLVED: To provide an agricultural covering film which is made of a polyethylene capable of being molded into a thin film excellent in flexibility and heat resistance and shows an excellent balance between impact resistance and rigidity even when it is thin. SOLUTION: This film has a film thickness of 5-30μm and is made of an ethylene/α-olefin copolymer which can form a 10μm-thick film having a dart impact strength of 100g or above and a tensile Young's modulus of 2.5×10<3> kg/cm<2> or above in each of MD and TD.
