All of our greenhouse plastics are commercial-grade and are designed for use in both residential & commercial greenhouse installations. Our greenhouse plastics are designed for years of continuous use in the designated application.

How Are Our Plastics Different?

We only offer commercial-grade greenhouse plastic which is designed specificly for greenhouse installations. Our plastics conform to high quality control standards and are manufactured in the United States not overseas like most of the greenhouse plastics sold online.

Why Purchase a High Quality Greenhouse Plastic?

When building your greenhouse most of the cost of construction is typically put toward labor. Because the plastic acts as the roof of the greenhouse it is very important to not cut corners and choose a plastic that is designed for years of continual use and has been ASTM tested to ensure that the plastic's physical properties are indeed what the seller is claiming. Many "four year plastics" are not engineered to survive four years in real world conditions. Additionally, in a commercial growing application the cost of the plastic is quickly dwarfed by the value of the plants inside. Again, another reason to invest in a high quality plastic.

Heavy Duty Greenhouse Plastic: A Robust Solution for Greenhouse Protection

When it comes to greenhouse coverings, durability and light transmission are two of the most important factors for ensuring a successful growing environment. The Heavy Duty Greenhouse Plastic is specifically designed to meet the needs of greenhouse owners looking for maximum protection from the elements without sacrificing the necessary light that plants need to thrive. Engineered with a unique weaving and coating process, this plastic is built to last, making it an ideal choice for those in demanding climates or for long-term installations.

What is Heavy Duty Greenhouse Plastic?

Heavy Duty Greenhouse Plastic is a reinforced polyethylene film designed for the most rigorous outdoor conditions. It combines high-density polyethylene (HDPE) strips that are woven together and then coated with low-density polyethylene (LDPE). This heat-sealed bonding process results in a material that is both strong and flexible, offering exceptional tear resistance and durability.

At 12 mil thickness, this plastic is thicker than most standard greenhouse films, providing a tough barrier against physical damage, such as punctures and stretching, while maintaining an impressive 87% light transmission rate. This means your plants get the sunlight they need to grow while the greenhouse structure is safeguarded from weather-related wear and tear.

Key Features of Heavy Duty Greenhouse Plastic

1. Durable Woven Structure: The core of this plastic is a weaving process that interlocks high-density polyethylene strips. This structure not only strengthens the material but also provides flexibility, ensuring that it can withstand movement from wind or accidental impacts without tearing. The woven design also helps distribute the force of any stress across the entire surface, further enhancing its durability.

2. Low-Density Polyethylene Coating: The outer layer of the plastic is coated with low-density polyethylene, which adds a layer of protection and helps create a smooth, sealed surface. This coating improves the plastic's resistance to punctures and abrasions, making it ideal for greenhouses in harsh environments, such as areas with strong winds, heavy rainfall, or fluctuating temperatures.

3. Heat-Sealed Bonding: The heat-sealed bond between the HDPE core and the LDPE coating ensures that the material remains cohesive under pressure. This bonding process eliminates weak points, making the plastic more resistant to tears and splits over time. This heat-sealed structure ensures a long-lasting material that can handle the demands of both small and large greenhouse setups.

4. 12 Mil Thickness:
At 12 mils thick, this plastic is built to provide heavy-duty protection. The added thickness makes it less prone to stretching and sagging, even after prolonged exposure to the elements. This is particularly important in greenhouses where wind, rain, or snow could potentially compromise thinner, less durable materials.

5. 87% Light Transmission: Despite its robust construction, the plastic allows 87% of natural sunlight to pass through, ensuring your plants receive adequate light for photosynthesis and growth. This high light transmission is balanced with its ability to diffuse light evenly throughout the greenhouse, reducing hot spots and ensuring that all plants receive uniform exposure.

Benefits of Heavy Duty Greenhouse Plastic

1. Unmatched Durability
The combination of woven HDPE and coated LDPE makes this plastic highly resistant to tearing, stretching, and puncturing. This level of durability means you won’t have to worry about frequent replacements, saving both time and money in the long term. Whether your greenhouse is exposed to strong winds, heavy snow, or other environmental stresses, this material can handle it.

2. Protection from Environmental Factors
In addition to its resistance to physical damage, the heavy-duty plastic provides excellent protection against weather elements. The material is resistant to UV radiation, which prevents it from degrading under prolonged sun exposure. Additionally, it acts as a shield against moisture, rain, and even snow, ensuring that the interior of your greenhouse remains a stable environment for your plants.

3. Superior Light Diffusion
With 87% light transmission, this plastic allows plenty of sunlight to reach your plants while diffusing it evenly throughout the greenhouse. This helps prevent the development of “hot spots” where concentrated sunlight could cause uneven plant growth or even scorch leaves. The even distribution of light ensures a balanced and healthy growing environment, which is crucial for maintaining plant health and maximizing yields.

4. Ideal for Large and Small Greenhouses
Whether you’re managing a commercial greenhouse or a smaller backyard setup, the Heavy Duty Greenhouse Plastic can adapt to your needs. Its strength and flexibility make it a versatile option for various structures, including hoop houses, cold frames, and high tunnels. The material can also be easily cut to size, making installation straightforward for different greenhouse designs.

5. Long-Term Investment
Investing in heavy-duty plastic sheeting means fewer replacements and repairs over time. The durability and longevity of this material reduce overall maintenance costs, making it a more economical choice compared to thinner, less durable alternatives. Its ability to resist degradation and weather-related damage makes it ideal for long-term use.

Practical Tips for Installing Heavy Duty Greenhouse Plastic

1. Secure Fastening
Ensure that the plastic is properly secured to your greenhouse frame to prevent it from flapping or shifting in high winds. Use proper fasteners, such as clips or wire locks, that are specifically designed for greenhouse installations.

2. Proper Overlapping

When covering large areas, make sure to overlap the seams by several inches and seal them with greenhouse tape to create a weather-tight seal. This will prevent leaks and drafts that could disrupt the internal climate.

3. Routine Maintenance
While the material is designed for durability, it’s still a good idea to inspect your greenhouse plastic periodically. Check for any signs of wear or damage, and patch any small holes or tears promptly to prevent them from worsening.

4. Cleaning for Optimal Light Transmission
Over time, dirt and debris can accumulate on the surface of the plastic, reducing light transmission. Cleaning the surface regularly with a mild soap solution and a soft brush or sponge will help maintain optimal light penetration for your plants.
