PURPOSE:To provide the titled film having excellent drip proofness and thermal welding resistance, by adding an ionomer resin, a surfactant and a thermal welding inhibitor to an ethylene/vinyl acetate copolymer. CONSTITUTION:0.1-5pts.wt. ionomer resin, 0.5-3pts.wt. surfactant such as polyethylene glycol monostearate and 0.03-3pts.wt. thermal welding inhibitor such as hexamethyldiamine stearate are mixed with 100pts.wt. ethylene/vinyl acetate copolymer having an MI of 0.1-10 and a vinyl acetate content of 5-20wt%. The mixture is molded into a film. EFFECT:An agricultural covering film which has excellent impact resistance and heat insulating properties, and can be easily burnt up after use and to which dust hardly adheres, can be obtd. |
