greenhouse film

Polyethylene (PE) Shelter Film

Its own texture is light (specific gravity of about 0.96 g / cm3), soft, easy to shape, good light transmission, non-toxic, is China's main varieties of agricultural film.

Its shortcomings are; weather resistance and poor thermal insulation, not easy to bond. If the production of greenhouse film, must be added to the aging resistance agent, non-dripping agent, thermal insulation agent and other additives, in order to be suitable for the production requirements.

The main products are:

① ordinary PE greenhouse film (also known as PE blow-molded agricultural film) does not add aging-resistant additives such as direct raw material blow molding production of white film, greenhouses and small and medium-sized greenhouse applications, generally in the spring and fall buckle greenhouse, the use of only 4-6 months, can only plant a season of crops, waste of energy, increase labor, production is gradually being phased out.

② PE anti-aging film (also known as longevity film, aging-resistant film) is added to the PE resin aging-resistant additives, by blow molding into a film. This film thickness of 0.08-0.12 mm, the use of up to 12 ~ 18 months, can be 2-3 seasons of crop cultivation, not only the use of prolonged period, cost reduction, energy saving, but also to make the yield and production value increased significantly, it is the focus of the promotion of facilities in the cultivation of varieties of agricultural film.

③ PE non-drip anti-aging film (also known as double-proof film, long-life drip film) at the same time has a drip, weather resistance, light transmission and good thermal insulation, anti-dripping effect can be maintained for 2-4 months, aging life of up to 12-18 months, is the performance of the more complete, widely used varieties of agricultural film, not only for greenhouses and large, small and medium-sized greenhouses, but also energy-saving day-lighting greenhouses in the early spring stubble cultivation is also more suitable.

④ PE heat preservation shed film this covering material can prevent infrared radiation to the atmosphere, can improve the temperature of the greenhouse 1-2 ℃, in the cold areas of the application of the effect is better.

⑤ PE multi-functional composite film has a variety of functions such as non-drip, heat preservation, weather resistance, longevity, etc. Some have the function of blocking ultraviolet rays, so that the shed UV transmission is reduced. Some of them can inhibit the formation of mycosis cyst disk and gray mold conidia. The use period can be up to 12-18 months.
 

It is usually produced by single-layer blown film production line and three-layer co-extruded blown film production line.
