摘要: An insect-repelling film or sheet which has a reflective spectrum in the ultraviolet region at a wavelength of less than 0.4 mu m, particularly a reflective spectrum peak at a wavelength of less than 0.4 mu m, a reflective spectrum with a ratio RA/RB of not less than 1.4 wherein RA is the ultraviolet reflectance and RB is the visible light reflectance at a wavelength of 0.5 mu m, and a visible light transmission of not less than 40 %,is useful as a cover for greenhouses and tunnels or for mulching of the ground for crop culture or as a repellent for various insect pests in agriculture, forestry and gardening.

摘要: An ethylene-a-olefin copolymer composition comprising two ethylene-a-olefin copolymers which are different in density, intrinsic viscosity and the number of short chain branching per 1000 carbon atoms. Extrusion processed materials, injection molded materials and films obtained from said composition are excellent in strength.
