PROBLEM TO BE SOLVED: To obtain the subject product composed of a polymer composition obtained by blending a high density polyethylene with an elastic polymer and a low-density polyethylene, excellent in flexibility, scratch resistance and transparency as well as tear strength and whitening resistance. SOLUTION: This film for agriculture is composed of at least one layer of a polymer composition mainly consisting of (A) a high-density polyethylene having 0.94-0.97g/cm<3> density and further contains (B) preferably 5-30wt.% of an elastic polymer and (C) preferably 10-40wt.% of a low-density polyethylene having 0.88-0.93g/cm<3> density. A high-density polyethylene having 0.1-5g/10min melt flow rate(MFR) (at 190 deg.C under 2.16kgf pressure) and 3-10 ratio of weight- average molecular weight/number-average molecular weight is preferably used as the component A. An ethylene-propylene elastic copolymer having 0.1-10g/10min MFR (at 230 deg.C under 2.16kgf pressure) is preferably used as the component B. A linear ethylene-α-olefin copolymer having 0.01-10g/10min MFR (at 190 deg.C under 2.16kgf pressure) is preferably used as the component C.
