Plastic Film Greenhouse

Definition of Film greenhouse

A film greenhouse is an innovative agricultural structure designed to optimize plant growth by harnessing natural sunlight while controlling environmental variables. Utilizing specialized polyethylene films, these greenhouses provide a protective barrier against adverse weather conditions, pests, and excessive UV radiation. The translucent films allow sunlight to penetrate, facilitating photosynthesis and creating an ideal microclimate for plant development. Film greenhouses are crucial for extending growing seasons, improving crop yields, and fostering optimal conditions for diverse plant species. Their cost-effectiveness and adaptability make them essential tools for modern agriculture, promoting sustainable and efficient food production.

Material of greenhouse

Its main components are made of metal skeleton and covering film

Metal skeleton

The metal frame of a greenhouse is its essential structural framework, often constructed from robust materials like galvanized steel or aluminum. Renowned for durability and resistance to corrosion, this framework ensures stability and longevity in varying weather conditions. Its modular design allows for easy assembly and customization, accommodating different greenhouse sizes and shapes. The metal frame provides the necessary support for covering materials, such as polyethylene or polycarbonate, creating a controlled environment that fosters ideal conditions for plant cultivation and growth.

Covering film

Greenhouse covering films are crucial components, typically made of polyethylene or polycarbonate, serving as protective layers for the structure. Polyethylene films are cost-effective and widely used, offering insulation and UV protection. Polycarbonate films provide durability and enhanced light diffusion. Both materials contribute to creating an optimal microclimate within the greenhouse, regulating temperature, humidity, and light exposure. The choice of covering film influences the greenhouse's efficiency, impacting plant growth and overall productivity by safeguarding against adverse weather conditions and facilitating controlled environmental conditions for diverse crops.

How to Maintain Clear Vinyl Sheeting Greenhouse

Cleaning of the film: During cleaning, use a long, soft brush and a triangular ladder or scaffolding to clean it section by section. During the application process, if the film is loose, it may be knocked up and down by the wind, potentially causing damage. Therefore, if you notice loose film, tighten it immediately.

Regularly check the parts and frames for corrosion and rust. If any issues are found, apply anti-corrosion paint immediately for maintenance.

Film cracks may occur during long-term use. Regular inspections are necessary. If cracks are found, repair them immediately using special plastic film repair tape to alleviate pressure during the repair. Alternatively, you can cover a certain area with another layer of new film.

What you should know when use saran wrap greenhouse

1. It is strictly prohibited to burn garbage and other debris inside and outside the greenhouse, because burning will damage the service life of the film and reduce its service life;

2. The dosage of biological products such as pesticides and herbicides should be limited when used;

3. When using other chemicals, be careful not to come into contact with the film, because many chemicals will react with the film, thus affecting the service life of the film.

FAQ

Q: 1.What does greenhouse film do?

A: Starting with polyethylene, a common greenhouse film used is 6 mil polyethylene. This is a smooth plastic that is placed on the roof of the greenhouse to protect the plants inside from the elements. It is an economical choice which will require replacement usually in 1-4 years.
