Abstract

The present invention relates to one kind of sunlight film for covering green house as modern gardening facility and its making process, and belongs to the field of agricultural technology. Low density polyethylene, ethylene-acetic acid copolymer, dripping agent, light stabilizer, composite antioxidant, diluent, light converting agent are mixed to produce concentrated mother material; mother material in 10-15 wt% and base material low density polyethylene or ethylene-acetic acid copolymer in 85-90 wt% are mixed homogeneously; and the mixture is extruded, blown into film and cooled to settle and processed through further steps to produce the sunlight film product. The sunlight film is used to penetrate sunlight, maintain temperature and convert ultraviolet ray into blue and red light essential for plant to perform photosynthesis and is superior to available plastic film for green house in light transparence.
