FILM FOR EGG APPLE CULTIVATION

摘要

PURPOSE:To provide the titled film which controls blight and improves color of egg apple, prepared by adding a specified surfactant to vinyl chloride resin to improve transmission of light of a specific wavelength. CONSTITUTION:The film is prepared by adding (B) at least 0.5pts.wt. nonionic surfactant and (C) 0.01-1.0pt.wt. fluorine-based surfactant and/or silicone-based surfactant to (A) 100pts.wt. vinyl chloride resin. The film contains no ultraviolet ray absorber and shows 70% or higher transmission of light in the wavelength of 350nm. It improves color of egg apple and controls blight by lowering himidity.
