This innovative greenhouse structure, enveloped in premium-grade plastic film, serves as the quintessential covering solution, revolutionizing agricultural cultivation and various related fields. Experience unparalleled growth and protection for your crops, making it the preferred choice for modern farmers aiming to maximize yield and quality.
Frame part
This essential component is crafted from robust metal materials like steel pipes and galvanized pipes. Each pipe is meticulously cut, bent, and expertly welded to form the sturdy skeleton of the greenhouse. The diameter and wall thickness of the steel pipe are critically chosen based on the greenhouse's size and its desired load-bearing capacity. For instance, smaller greenhouses might employ steel pipes with a diameter ranging from 25-32mm, whereas larger greenhouses require pipes with more substantial diameters and thicker walls. This ensures the structure remains stable, effectively supporting the plastic films, snow, wind loads, and other external pressures.
Frames are available in a plethora of shapes, with arches and ridges being the most prevalent. The arch greenhouse frame is circular, facilitating superior coverage of the plastic film, ensuring uniform force distribution, and providing an open internal space. On the other hand, the ridge greenhouse resembles a house ridge, offering excellent drainage benefits and enhanced spatial flexibility, suitable for specific planting techniques demanding greater vertical clearance.
Plastic film
As a pivotal covering material for greenhouses, plastic films are indispensable. Common varieties include polyethylene (PE) film and polyvinyl chloride (PVC) film. The PE film is economically priced, boasts remarkable flexibility, and provides high light transmittance, typically ranging from 85% to 93%. It also offers substantial puncture resistance. Meanwhile, the PVC film excels in thermal insulation compared to the PE film, with light transmittance levels between 80% and 90%. Despite its slightly higher cost, its performance may be impacted over time due to potential plasticizer leakage.
Plastic film thickness offers diverse choices, generally ranging from 0.08-0.2mm. Thicker films promise enhanced durability, albeit at a higher cost. Color variations also exist, with transparent films delivering optimal light transmission conducive to plant photosynthesis. Some films incorporate special pigments, such as blue films, which modulate light quality, providing a unique boost to the growth of certain plants.
Ventilation system
Natural ventilation stands as one of the preferred methods for aerating plastic film greenhouses. This is typically achieved by strategically placing vents on the greenhouse sidewalls or roofs. Sidewall vents may feature manually operated plastic steel windows or roll film vents controlled by film rollers, offering ease of operation and adjustable vent sizes to suit specific needs. Roof vents often employ the roof ridge ventilation method, with ventilation windows set along the ridge to expel hot air via natural air rising, ensuring efficient cooling and ventilation.
In larger plastic film greenhouses, mechanical ventilation systems are frequently utilized. These systems predominantly comprise fans and ventilation pipes. Fans are generally installed on one side of the greenhouse, while ventilation pipes are distributed throughout. This allows the fresh air moved by the fans to be uniformly spread across the greenhouse's interior. Though this method boasts superior ventilation efficiency, it also incurs higher equipment and operational costs.
Sunshade system
The sunshade net is a central feature of the plastic film greenhouse sunshade system. Sunshades may be located either inside or outside the greenhouse. Internal sunshade nets are favored for their ease of installation and maintenance, although their shading effectiveness is somewhat limited. External sunshades provide superior shading by directly blocking sunlight from the plastic film, thus reducing internal heat accumulation. However, they are more vulnerable to environmental factors like wind and rain, necessitating a more robust installation.
Sunshade nets vary in shading rates, offering a spectrum of options such as 40%, 60%, and 80% shading rates. For plants requiring lower light intensity, such as edible fungi and flower seedlings, selecting a net with a higher shading rate can prevent damage from intense sunlight.

Lower cost
Compared with glass greenhouses and polycarbonate sheet greenhouses, the construction cost of plastic film greenhouses is much lower. The plastic film itself is cheap, and the frame structure is relatively simple, and the material cost and installation cost are relatively low. This makes plastic film greenhouse in agricultural production more easily accepted by the majority of farmers, especially suitable for small and medium-sized farmers. |
Good light transmission
Transparent plastic film can provide good natural lighting conditions, so that the greenhouse interior light is sufficient, conducive to plant photosynthesis. Moreover, the light transmission performance of plastic film can be adjusted by selecting different film materials and thicknesses to meet the requirements of different plants for light intensity and light quality. |
Construction flexibility
The size and shape of the plastic film greenhouse can be flexibly designed according to the actual site and planting needs. It can be a small simple greenhouse for home gardening or small seedling breeding; It can also be a large multi-storey greenhouse for large-scale vegetable and flower planting. The assembly of the frame structure is relatively simple and the construction period is short. |
1. How long is the delivery time?
According to your greenhouse size and system, the delivery time is usually 15-60days.
2. Can you supply sample?
