PURPOSE:To obtain a covering film made of a thermoplastic resin containing polyethylene oxide, having excellent transparency, anti-stick quality and heat- insulation and suitable mainly for agricultural use. CONSTITUTION:The objective film is produced by forming a thermoplastic resin (preferably polyolefin resin such as PVC or ethylene-vinyl acetate copolymer) containing polyethylene oxide (preferably having an average molecular weight of 10,000-300,000). The content of polyethylene oxide is preferably 1-10 pts.wt. per 100 pts.wt. of the thermoplastic resin. |
