The main structure of the multi-span agriculture film greenhouse is simple and practical, with the low cost of construction and operation. In the cold area, the top can be designed with double arches and double-layer films, which can effectively prevent heat loss and the invasion of cold air, with good insulation effect and low operation cost in the winter.

The skeleton of the multi-span agriculture film greenhouse adopts a hot-dip galvanized steel structure, which is strong and durable. The hot-dip galvanized steel structure has strong corrosion resistance and it can be used for more than 30 years. The cover film is made of PO film, which has anti-ultraviolet and anti-drip function, and it is very economical. The greenhouse is equipped with a temperature control system. The system sets the temperature according to individual needs. When the indoor temperature is high or low, the greenhouse system will automatically start work, saving time and effort, and controlling freely.

Advantage of multi-span agriculture film greenhouse
1.Structure of greenhouse
High quality hot-dip galvanized steel; The Galvanized ...
... layer is above 240g/m2; Compared to electrical galvanized pipe, hot-dip galvanizing pipe is covered of zinc layer inside and outside of the pipe, so it is not easy to get rusty. The guarantee period is more than 30 years.

2. Covering material
The covering material is PO film, which has an anti-ultraviolet and anti-drip function.
Thickness of film: 0.12mm, 0.15mm, 0.18mm, 0.22mm.
Film color: white, blue, transparent.
Transmittance rate: >70%.
Service time: >5 years.

The technology of multi-span agriculture film greenhouse
Multi-span agriculture film greenhouse 5 layers co-extrusion blown film is the most popular and latest packaging technology in the world. The significant advantage is this new technology makes the film more flexible, that means we can design the special formula for each layer according to the client’s specification to produce an excellent film. On the other hand for stretch wrap film, 5 layers technology has perfect mechanical properties, even better than 11 layer cast film, but the output is lower than the cast line. The application such as greenhouse film, heat shrink film, stretch film, silage film, and another flexible packing.
