The plastic film greenhouse is an innovative and essential greenhouse structure, expertly designed with plastic film as its primary covering material. This versatile and highly efficient covering is renowned for its extensive application in the realm of agricultural cultivation and beyond. It has become a favored choice for farmers and growers seeking to optimize their produce yield and quality, making it an indispensable asset in modern agricultural practices.
Frame part
Crafted with precision, the VERTEX Plastic Film Greenhouse's framework is typically constructed using robust metal materials such as steel and galvanized pipes. These components are meticulously cut, bent, and welded to create a resilient skeleton that forms the backbone of your greenhouse. The dimensions of these steel pipes-diameter and wall thickness-are thoughtfully selected based on the greenhouse's scale and its intended load capacity. For instance, compact greenhouses may utilize steel pipes with a diameter of 25-32mm, while larger greenhouses might opt for pipes with greater diameters and thickness to ensure superior stability. This robust structure is designed to adeptly support the weight of plastic films, as well as resist environmental stresses such as snow and wind loads.
The versatility of frames extends to their shapes, commonly featuring elegant arches and practical ridges. The arch-shaped greenhouse frames offer a circular design, promoting optimal plastic film coverage with uniformly distributed force, resulting in a spacious interior. Conversely, the ridge greenhouse mirrors the familiar ridge shape of a traditional house, offering enhanced drainage capabilities and greater spatial flexibility, making it ideal for certain planting techniques that necessitate elevated space.
Plastic film
A cornerstone of greenhouse covering materials, plastic films such as polyethylene (PE) and polyvinyl chloride (PVC) are essential. PE film stands out for its affordability, excellent flexibility, and high light transmittance ranging between 85%-93%, coupled with admirable puncture resistance. On the other hand, PVC film boasts superior thermal insulation and can achieve light transmittance between 80%-90%, albeit at a slightly higher cost and potential performance decline over time due to plasticizer leakage.
Plastic film thickness is available in various options, generally from 0.08 to 0.2mm. Thicker films promise enhanced durability, albeit at increased costs. The film colors vary, with transparent films offering maximum light transmission, fostering plant photosynthesis. Additionally, films with unique pigments such as blue can modulate light quality, significantly boosting the growth of certain plant varieties.
Ventilation system
Natural ventilation ranks among the most prevalent methods for regulating airflow in a plastic film greenhouse. This is achieved by strategically placed vents along the side walls or rooftops. Side wall vents may consist of manually operated plastic steel windows or roll-up film vents manipulated by film rollers. The latter offers ease of operation, with adjustable vent sizes tailored to specific requirements. Roof venting typically employs the ridge ventilation technique, with vents positioned along the rooftop ridge, utilizing natural hot air rise to efficiently expel heated air, facilitating effective cooling and ventilation.
For larger greenhouses, mechanical ventilation systems serve as an impactful alternative. These systems predominantly rely on fans and ventilation ducts, with fans installed on one side of the greenhouse and ducts distributed throughout the interior. This setup ensures the even distribution of fresh air drawn by the fans to every corner, delivering exceptional ventilation efficiency, albeit with higher equipment and operational costs.
Sunshade system
The sunshade system in a plastic film greenhouse prominently features sunshade nets as its primary component. These nets can be installed either internally or externally. An internal sunshade net offers ease of installation and maintenance, though with slightly diminished shading efficacy. Conversely, external sunshades excel in blocking direct sunlight on the plastic film, significantly reducing heat accumulation inside the greenhouse. However, they require a sturdier installation due to exposure to elements like wind and rain.
Sunshade nets are available in various specifications, defined by their shading rates of 40%, 60%, or 80%. For plant species that thrive under low light conditions, such as edible fungi and delicate flower seedlings, selecting a higher shading rate net is recommended to shield them from potential damage caused by 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?
Small parts can be supplied, but you should pay the express cost.
3. Can your company supply greenhouse design?
Our company can give greenhouse design according to your land and plan after deposit. And we can give simple drawing before signing contract.
