Zusammenfassung:	PURPOSE:A film for agriculture having extremely improved heat retaining properties without damaging processing characteristics, obtained by adding barium sulfate to a base consisting of an olefinic resin. CONSTITUTION:1-20pts.wt., preferably 1-10pts.wt. barium sulfate is added to 100pts.wt. base consisting of an olefinic resin, preferably ethylene-vinyl acetate copolymer. The ethylene-vinyl acetate copolymer to be used as the base has a vinyl acetate content of 5.0-30.0wt% and a MI of 1.0-20.0, and an improver for weather resistance such as a benzophenone type substance, etc. is preferably added to the blend when the copolymer or polyethylene is used.
