When it comes to greenhouse plastic, the thickness of the sheeting is a critical feature to consider. Plastic sheeting is typically measured in mils, which is a unit of measurement equalling one-thousandth of an inch (0.001 inch) and is distinct from millimetres. Greenhouse covers are commonly offered in thicknesses ranging from 3 to 12 mils, with 6 mils being the most popular option. The ideal thickness for a greenhouse cover depends on various factors, including the frame material, intended application, and expected weather conditions. Thicker plastic sheeting is generally more durable and better suited for harsh weather conditions, while thinner sheeting is used for general applications. UV protection, longevity, light transmission, and cost are also important considerations when choosing greenhouse plastic.

What You'll Learn
Typical thicknesses range from 3 to 12 mils
Greenhouse covers are typically offered in a range of thicknesses from 3 mil to 12 mil. The thickness of the plastic sheeting is measured in "mils", which is a unit of measurement equalling one-thousandth of an inch or 0.001 inch. This unit of measurement is different from a millimeter, which is approximately 39 mils thick.
The most common thickness for greenhouse covers is 6 mil. This thickness is offered by many companies, including Farm Plastic Supply, Bootstrap Farmer, and Americover. 6 mil plastic films are a good option for backyard gardeners and growers as they are durable, long-lasting, and affordable. They can also be easily installed without tearing and can withstand tough weather conditions. Additionally, 6 mil plastic films have high light transmittance, allowing over 90% of light to pass into the greenhouse, which is essential for plant growth.
However, the ideal thickness of greenhouse plastic depends on various factors, such as the frame material, the application of the sheeting, and the expected weather conditions. For example, in areas with heavy snow, rain, or heat, thicker plastic sheeting may be required. On the other hand, thinner plastic sheeting is typically used for general applications, such as creating temporary walls and covering materials. Medium-thickness plastic, such as 6 mil, is suitable for greenhouse covers and enclosures, while the thickest sheeting is reserved for heavy-duty applications like water retention liners.
Growers should also consider the longevity of the plastic sheeting. While 6 mil plastic films are commonly used, they may only last up to four years before requiring replacement. Thicker plastic, such as 10 mil or 12 mil, may offer greater durability and a longer lifespan. Additionally, UV inhibitors and string reinforcement can lengthen the life of the greenhouse cover. For example, string-reinforced 4-year UV-resistant 10 mil clear greenhouse plastic sheeting is available from Farm Plastic Supply.

Common thicknesses are 4, 6 and 10 mils
When it comes to greenhouse plastic, the thickness of the sheeting is a critical feature. The most common thicknesses for greenhouse covers are 4, 6, and 10 mils, with the most popular option being 6 mil. It's important to note that "mil" is a unit of measurement that equals one-thousandth of an inch, so it's different from a millimeter.
A 4 mil poly greenhouse plastic sheet can typically last for about a year. It is ideal for narrow tunnels and overwintering houses. For backyard gardeners and growers, 6 mil greenhouse plastic is more than sufficient. It offers decent protection against weather elements, UV rays, and other harmful factors. It also has a high light transmission rate of over 90%, which is essential for plant growth. This thickness is also easy to install without tearing and typically comes with a four-year warranty.
For larger, more commercial operations, 10 mil greenhouse plastic may be required. Thicker plastic sheeting is generally used in harsher weather conditions, such as heavy snow, rain, or heat. It's important to consider the frame material, the application of the sheeting, and the expected weather conditions when choosing the thickness of the plastic sheeting.
The thickness of the plastic sheeting can also be increased by using string-reinforced or woven poly or nylon scrim-reinforced materials, which provide added strength and durability without significantly increasing thickness.

Thickness depends on weather conditions
The thickness of greenhouse plastic is typically offered in a range from 3 mil to 12 mil, with the most common thickness being 6 mil. However, the thickness of the plastic sheeting depends on various factors, including the expected weather conditions.
If the greenhouse is subject to heavy snow, rain, or heat, thicker plastic sheeting should be used. In hot weather conditions, metal frames can cause the plastic to melt, so a felt barrier is recommended to reduce deterioration. Thicker plastic is also more durable and provides better protection against weather elements and harmful UV rays. For instance, 6 mil poly plastic provides better durability and strength compared to 4 mil poly plastic.
On the other hand, in milder weather conditions, thinner plastic sheeting can be used. Medium-thickness plastic, such as 6 mil plastic, is suitable for general greenhouse covers and enclosures. It is also more affordable and can be a long-lasting option.
To further enhance the durability of the plastic sheeting, growers can consider string-reinforced sheeting or woven poly or nylon scrim-reinforced material, especially in high wind locations. Additionally, UV inhibitors can lengthen the life of the greenhouse cover.
When choosing the thickness of greenhouse plastic, it is essential to consider the specific weather conditions and the desired level of protection against the elements. Consulting with an expert can help evaluate the unique growing conditions and select the most suitable thickness and type of plastic sheeting.

Thickness depends on frame material
The thickness of greenhouse plastic is typically offered in a range from 3 mil to 12 mil, with the most common thickness being 6 mil. However, the thickness of the plastic sheeting depends on several factors, including the frame material, the application of the sheeting, and the expected weather conditions.
If your greenhouse is made from weaker materials like PVC, you should be careful not to use plastic sheeting that is too heavy, as this could cause the structure to collapse, especially during strong weather events. In general, thicker plastic sheeting should be used in harsh weather conditions, such as heavy snow, rain, or heat. Metal frames can also cause added friction to plastic or cause melting in hot weather, so a felt barrier is recommended in this case.
For narrow tunnels and overwintering houses, 3 or 4 mil film is a common choice for one-year use. For backyard gardeners and growers, 6 mil greenhouse plastic is typically strong enough for their needs. However, for larger, more commercial operations, 10 mil greenhouse plastic may be required.
To increase the durability of the plastic sheeting without increasing the thickness, you can consider string-reinforced sheeting, which can lengthen the life of your greenhouse cover. Additionally, UV inhibitors can also prolong the lifespan of the plastic.

Polyethylene is the best for strength and durability
Greenhouse covers are typically offered in a range of thicknesses, from 3 to 12 mil, with the most common thickness being 6 mil. The strength of the plastic typically increases with thickness.
Reinforced polyethylene film is stronger than 6-mil greenhouse plastic due to its inner layer of cord, which makes it windproof, puncture-proof, and tear-resistant. However, it only lasts about four years due to UV degradation.
Polyethylene (PE) plastic is a versatile and reliable material used in various industries, including packaging, construction, agriculture, and electrical and electronics. One of its standout properties is its high strength and durability.
PE plastic is highly resistant to mechanical stress and impacts, making it ideal for applications requiring long-lasting performance. It is also chemically resistant, with the ability to withstand exposure to various substances, including acids, alkalis, and solvents. This feature ensures the material's integrity and longevity.
In the construction sector, PE is used for water pipes, geomembranes, and insulation materials due to its chemical resistance and water-tightness. In agriculture, it is used for irrigation systems, mulching films, and greenhouse coverings because of its moisture resistance and durability.
High-density polyethylene (HDPE) is a type of PE plastic known for its exceptional durability and strength. Compared to other plastics, HDPE has a higher tensile strength and impact resistance, making it less susceptible to breakage, dents, and scratches. Its resistance to mould, rot, and insects makes it suitable for food and beverage packaging, consumer goods, and landfill lining.
Overall, polyethylene, especially HDPE, is an excellent choice for greenhouse coverings due to its strength, durability, and resistance to various environmental factors.
