Hey there, fellow greenhouse enthusiasts! As a supplier of plastic film greenhouses, I've seen firsthand the impact that the right plastic film can have on a greenhouse. It's not just about covering the structure; it's about creating the perfect environment for your plants to thrive. So, what kind of plastic film is best for a greenhouse? Let's dive in and find out.
Understanding the Basics of Greenhouse Plastic Film
Before we get into the nitty - gritty of choosing the best plastic film, let's understand what it does. Greenhouse plastic film acts as a barrier between the inside and outside environment. It traps heat and light, creating a warm and controlled space for plants to grow. It also protects plants from harsh weather conditions, pests, and diseases.
There are several types of plastic films commonly used in greenhouses, each with its own set of pros and cons.
Polyethylene Film
Polyethylene film is one of the most popular choices for greenhouse covering. It's affordable, easy to install, and comes in different thicknesses and qualities.
- Low - Density Polyethylene (LDPE): This type of polyethylene is flexible and has good clarity. It's great for short - term use, like season - extension greenhouses. However, it doesn't last as long as some other types of plastic. It can become brittle over time, especially when exposed to UV rays.
- High - Density Polyethylene (HDPE): HDPE is more durable than LDPE. It's thicker and can withstand more wear and tear. It also has better UV resistance, which means it will last longer in the sun. But it's a bit stiffer, so it might be a bit more challenging to install.
- Linear Low - Density Polyethylene (LLDPE): LLDPE combines the best of both worlds. It has the flexibility of LDPE and the durability of HDPE. It's also very puncture - resistant, making it a great choice for areas with high winds or where there's a risk of physical damage.
Polyvinyl Chloride (PVC) Film
PVC film is another option for greenhouse covering. It has excellent light transmission, which is crucial for plant growth. It also retains heat well, helping to keep your greenhouse warm during colder months.
One of the biggest advantages of PVC film is its long lifespan. It can last up to 10 years or more with proper care. However, it's more expensive than polyethylene film. And it requires special cleaning and maintenance. If not cleaned regularly, it can develop a sticky residue, which can reduce light transmission.
Ethylene - Vinyl Acetate (EVA) Film
EVA film is a newer type of greenhouse plastic. It has high light transmittance and good heat retention. It's also very flexible and easy to install.
EVA film is known for its excellent UV resistance. It can maintain its clarity and performance for a long time, even when exposed to the sun. However, it's not as widely available as polyethylene or PVC film, and it can be a bit more expensive.
Factors to Consider When Choosing the Best Plastic Film
- Climate: If you live in an area with extreme weather conditions, you'll need a more durable plastic film. For example, in areas with high winds, a puncture - resistant film like LLDPE would be a good choice. In colder climates, a film with good heat retention, like PVC or EVA, would be beneficial.
- Budget: Your budget will also play a big role in your decision. Polyethylene film is generally the most affordable option, while PVC and EVA films are more expensive. But remember, a more expensive film might last longer, so it could save you money in the long run.
- Plant Requirements: Different plants have different light and temperature requirements. If you're growing plants that need a lot of light, a film with high light transmittance, like PVC or EVA, would be ideal.
- Greenhouse Type: The type of greenhouse you have can also affect your choice of plastic film. For example, Polytunnel Plastic Greenhouses often use polyethylene film because it's easy to install and relatively inexpensive. Clear Plastic Sheets Greenhouse might benefit from a film with high clarity, like EVA or PVC. And Farm Tunnel Greenhouse could use a durable film that can withstand the rigors of farm life, such as HDPE or LLDPE.
Our Recommendations
As a plastic film greenhouse supplier, I've helped many customers choose the right plastic film for their needs. Here are some general recommendations:
- For beginners or budget - conscious growers: Low - density polyethylene (LDPE) is a great starting point. It's inexpensive and easy to work with. You can use it for a season or two to see if greenhouse gardening is right for you.
- For long - term use and professional growers: LLDPE or PVC film would be a better choice. They offer durability and performance, which are essential for commercial operations.
- For those who want the latest technology and best performance: EVA film is worth considering. It offers excellent light transmission, heat retention, and UV resistance.
