Agricultural plastic film

摘要

An agricultural plastic film improved in retention of infrared radiation which comprises an olefin resin film produced by forming a composition comprising 100 parts by weight of an olefin resin (A) and 2 to 25 parts by weight of a compound oxide (B) comprising SiO2 and at least one member of the oxides of metals selected from Groups II, III and IV of the periodic table, the ratio of the refractive index (nA) of said olefin resin to that (nB) of said compound oxide, nA/nB, being within a range of 0.99 to 1.02, into film.
