PROBLEM TO BE SOLVED: To obtain a film for packing rubber excellent in mechanical strength and impact resistance, difficult in breakage, when packaging rubbers, easy in separation from the rubbers, when it is melted and kneaded with the rubber, and useful for packaging the rubbers, by using an ethylene-α-olefin copolymer having specific characteristics as main component. SOLUTION: This film for packaging rubbers contains as main component an ethylene-α-olefin copolymer having a density (d) of 0.880-0.915 (g/cm<3> ), a melt flow rate (MFR2.16 ) of 0.01-200 (g/10min) under a load of 2.16kg at 190 deg.C, a MFR21.6 /MFR2.16 ratio of 10-20 wherein MFR21.6 is a melt flow rate under a load of 21.6kg at 190 deg.C, and a mol.wt. distribution (Mw /Mn ) of 2.0-4.0. The film preferably comprises 10-100wt.% of the above copolymer and 90-0wt.% of a high pressure method low density polyethylene.
