With the development of agriculture, the scale of the development of the greenhouse project has become wider and wider. The application of two-color mulching film has brought relatively large changes to traditional agricultural production and has made important contributions to the development of my country's vegetable industry. With the continuous increase of film production technology and the objective needs of agricultural production, there are more and more types of agricultural films.

Polyolefin film is a new type of agricultural film. It is composed of polyolefin raw materials and additives such as polyethylene olefin and vinyl acetate. It combines the advantages of polyethylene film and vinyl acetate film. Two-color film has the characteristics of high tensile strength, aging resistance, long fog, and high light transmittance. It can be used continuously for 5-6 years, and the old film is easy to reuse. Po film was invented in Japan. In recent years, Chinese manufacturers have begun to produce and promote, but their application areas are relatively small.

In the past, fruits and vegetables were mostly eaten during this season, but now they are very different. Using greenhouse cultivation techniques, we can eat fruits in different seasons. The light transmittance of the Po film is higher than that of the PE film. The temperature of the Po film covering the greenhouse is about 1°C higher than that of the PE film greenhouse, and the Po film has good thermal insulation performance; the greenhouse ground temperature is about 2°C higher than that of the plastic film greenhouse.

Two-color mulching film can be used in edible fungus greenhouse, sericulture greenhouse, aquaculture greenhouse, hydroponic anti-seepage layer, outdoor heat preservation and antifreeze, vegetable greenhouse, animal husbandry, flower shading, lighting (adjusting flowering period), etc.

main feature:

1. Mainly used in summer and autumn. When covering, the white face is facing upwards and the reflective ability is strong. The black interior does not allow light to pass through and plays a role in shading and cooling. The temperature in the greenhouse is much lower than other tarpaulins and mulching films, which has a strong effect on the prevention and growth of pests and diseases.

2. In winter, it can remove the blackness and heat on the snow surface. The black and white functional dimming film can block and reflect most of the infrared (heat) in the greenhouse from irradiating to the outside of the greenhouse, which plays a role of heat preservation.

The above is the knowledge points about two-color mulch film introduced by Qingzhou Luhong Plastic Co., Ltd. I hope our sharing is the information you need.
