As an AI language model, I don’t have physical products or inventory. However, there are several types of greenhouse plastic films available in the market that are commonly used for covering polytunnel greenhouses.

Here are a few examples:

  1. Polyethylene (PE) Film: Polyethylene is a popular choice for greenhouse coverings due to its affordability and durability. PE films come in various thicknesses and qualities, ranging from economy-grade films to high-performance, UV-stabilized options. They provide good light transmission and are easy to install.
  2. Ethylene-Vinyl Acetate (EVA) Film: EVA films are known for their high light transmittance and excellent thermal properties. They allow more sunlight into the greenhouse while providing good insulation. EVA films are often resistant to yellowing and have a longer lifespan compared to standard polyethylene films.
  3. Polyvinyl Chloride (PVC) Film: PVC films are another option for greenhouse coverings. They offer good light transmission and durability. PVC films are resistant to tearing and can withstand extreme weather conditions. However, they may have a shorter lifespan compared to other options and require proper UV stabilization to prevent degradation.
  4. Polyolefin (PO) Film: Polyolefin films are a newer type of greenhouse covering that combines the qualities of PE and PVC films. They are often UV-resistant, durable, and have good light transmission. Polyolefin films are known for their long lifespan and ability to withstand harsh weather conditions.

When choosing a greenhouse plastic film, factors such as light transmission, UV resistance, durability, and cost should be considered based on your specific requirements and the climate in which the greenhouse will be used. It’s recommended to consult with greenhouse suppliers or manufacturers to determine the most suitable film for your needs.

How to choose greenhouse plastic film ？

Choosing the right greenhouse plastic film requires considering several factors to ensure it meets your specific needs and provides optimal growing conditions.

Here are some key considerations when selecting greenhouse plastic film:

  1. Light Transmission: Light is crucial for plant growth, so it’s important to choose a plastic film that allows sufficient sunlight to penetrate. Look for films with high light transmission properties, typically measured as a percentage. Different crops may have varying light requirements, so consider the specific needs of your plants when selecting the film.
  2. UV Stability: Ultraviolet (UV) radiation from the sun can degrade greenhouse plastic over time. Look for films that are UV-stabilized or have UV inhibitors to prevent premature degradation and yellowing. UV stability is essential for maintaining the film’s transparency and extending its lifespan.
  3. Durability and Tear Resistance: Greenhouse plastic should be able to withstand environmental factors such as wind, hail, and other potential sources of damage. Consider films that are durable and tear-resistant, as they will provide better longevity and protection for your greenhouse structure and plants.
  4. Insulation and Energy Efficiency: The plastic film’s ability to retain heat and provide insulation is important for maintaining a stable and favorable growing environment. Look for films with good insulation properties that can help regulate temperature fluctuations and reduce heating costs, especially in colder climates.
  5. Anti-Condensation Properties: Condensation can form on the inner surface of the greenhouse plastic, potentially causing water droplets to fall on the plants. Some films are designed with anti-condensation properties that help minimize condensation buildup, preventing damage to the plants and improving light transmission.
  6. Cost and Budget: Consider your budget and the cost-effectiveness of the greenhouse plastic film. Different films vary in price based on their quality, durability, and special features. Evaluate the long-term benefits and lifespan of the film relative to its cost to make an informed decision.
  7. Climate Considerations: Take into account the climate in which your greenhouse will be located. If you experience extreme weather conditions such as high winds, heavy snowfall, or intense sunlight, choose a film that can withstand and protect against these elements.
  8. Supplier Reputation and Warranty: Purchase greenhouse plastic film from reputable suppliers or manufacturers known for producing high-quality products. Check customer reviews and inquire about warranties or guarantees that cover film defects or premature degradation.

It’s advisable to consult with greenhouse experts, suppliers, or manufacturers who can provide guidance based on your specific requirements and local climate conditions. They can help you choose the most suitable greenhouse plastic film for your needs and ensure successful plant cultivation.
