Abstract

The invention relates to a multi-functional polyethylene farm film, which is characterized in that the farm file consists of low density polyethylene, metallocene linear polyethylene, red and orange light conversion agent, blue light conversion agent, anti-aging agent, and dripping agent; and the weight proportion follows that: 100 proportion of low density polyethylene being used as base material, 20 proportion of metallocene linear polyethylene, 0.05-1.1 proportion of red and orange light conversion agent, 0.05-1.1 proportion of blue light conversion agent, 0.6-1.6 proportion of antioxidant 1076, 0.5-1.4 glycerol single acid ester, and 0.3-0.8 proportion of UV-531. The multi-functional polyethylene farm film of the invention has the advantages that the application of the film can lead crop yielding to increase by 20-25 percent, can lead the effective life of the farm film to be up to 4-5 years, can ensure no-dripping valid period to be prolonged for 5-6 months, and can increase tensile and puncturing intensity by 15-20 percent, and meanwhile, the effect of high transparency and low ambiguity is similar to that of an EVA film.

Description

technical field [0001] The invention relates to the field of polyethylene agricultural film. Background technique [0002] Commonly used polyethylene agricultural film is processed from ordinary polyethylene resin. Its disadvantage is that it has a single function and does not have the functions of light conversion, aging resistance, anti-fog, and high strength. Contents of the invention [0003] The purpose of the present invention is to provide a long-acting multi-functional polyethylene agricultural film with light conversion, aging resistance, anti-fogging and high strength for the above-mentioned shortcomings of the existing polyethylene agricultural film. [0004] The invention is composed of low-density polyethylene, metallocene linear polyethylene, red-orange light conversion agent, blue light conversion agent, anti-aging agent, and dripping agent; the weight ratio is as follows: [0005] Low density polyethylene as base material 100 Metallocene linear polyethylen...
