摘要：
A film suitable for an agricultural covering material is formed from a resin composition comprising a blend comprising (A) an ethylene/.alpha.-olefin random copolymer having a low melt flow rate and (B) an ethylene/.alpha.-olefin copolymer having a high melt flow rate. The random copolymer (A) has a density (D.sub.A) of 0.935 to 0.950 g/cc and the random copolymer (B) has a density (D.sub.B) of 0.905 to 0.935 g/cc, and the density (D.sub.B) of the random copolymer (B) satisfies the requirement of D.sub.B .ltoreq.0.9D.sub.A +0.09 in which D.sub.A stands for the density of the copolymer (A).
