The Farm Plastic Supply 6 Mil Greenhouse Plastic, 25x40 ft is the best greenhouse plastic sheeting choice for a broad clear cover, with stated 4-year UV resistance and greater than 90% light transmittance. For a long frame, compare the 24 x 50 ft roll; for reinforced material, consider the 10 mil string-reinforced option.

The right roll is the one that covers your frame with enough material left for secure attachment. Measure across the roof and sides, then along the structure before choosing a size.

If you are still deciding between film and rigid panels, see our guide to polycarbonate greenhouse panels. For a walk-in frame, our walk-in tunnel greenhouse guide explains how cover shape and structure affect fit.

How we chose greenhouse plastic sheeting

We compared dimensions, thickness, material, light details, reinforcement and UV protection stated by each brand. We gave more weight to products that pair a practical cover size with features that match common greenhouse needs.

We did not test these covers outdoors. Claims about UV resistance, tear resistance and light transmission come from the brands, so the clearest differences are size and construction.

The picks include broad rolls for full covers, plus narrower and shorter options for repairs or small structures. That mix matters because a roll can have suitable film but still leave a frame partly uncovered if its dimensions are wrong.

Which greenhouse plastic sheeting fits each frame?

The Farm Plastic Supply 25 x 40 ft roll suits broad covers, while the other sizes fit longer runs, compact frames, repairs or special material needs. Measure the film path over the frame, not just the ground footprint.

Farm Plastic Supply 6 Mil Greenhouse Plastic, 25x40 ft: Best for large frames

8.9/10Our score

• 6 mil polyethylene
• 25 x 40 ft
• 4-year UV resistance
• Greater than 90% light transmittance

This 25 x 40 ft clear polyethylene roll is 6 mil thick, with stated 4-year UV resistance and greater than 90% light transmittance. Measure the frame and allow for attachment before choosing this size.

See it on Amazon

Pros

• 25 x 40 ft sheet
• Stated 4-year UV resistance
• Greater than 90% light transmittance

Cons

• May be more material than a small frame needs

Farm Plastic Supply’s 25 x 40 ft clear polyethylene sheet is 6 mil thick. The brand states 4-year UV resistance and greater than 90% light transmittance, making it a strong starting point for a larger frame that needs clear film.

The width and length leave room to wrap over a roof and down the sides, though the actual fit depends on the arch and fastening edges. Sketch the path and measure it before ordering, because a curved roof uses more film than its footprint suggests.

Farm Plastic Supply describes the film for hoop houses and crop patches. That makes this size useful for a full replacement or a project where you want extra film for overlap.

Choose it for broad, clear coverage when your measurements fit within 25 x 40 ft. Skip it for a small frame if you do not need the extra material, or if the 24 x 50 ft shape fits your long tunnel better.

Farm Plastic Supply 6 Mil Greenhouse Plastic, 24x50 ft: Best for long tunnels

8.7/10Our score

• 6 mil polyethylene
• 24 x 50 ft
• 4-year UV resistance
• Clear film

This 24 x 50 ft clear polyethylene roll is 6 mil thick, with stated 4-year UV resistance. It trades 1 ft of width for 10 ft of length compared with the 25 x 40 ft option.

See it on Amazon

Pros

• 50 ft length for long runs
• Stated 4-year UV resistance
• Clear polyethylene

Cons

• Less width than the 25 x 40 ft option

This Farm Plastic Supply roll is 24 x 50 ft, giving it 10 ft more length and 1 ft less width than the 25 x 40 ft pick. It is 6 mil clear polyethylene with stated 4-year UV resistance.

The longer dimension helps when a tunnel needs a continuous run. Confirm that 24 ft of width covers the arch from one lower edge, over the roof, to the other lower edge, with enough left to attach securely.

Farm Plastic Supply states greater than 90% light transmittance for its clear film. The amount of light plants receive also depends on the greenhouse’s position and surrounding shade.

Choose it for a long structure when length matters more than the extra foot of width. Skip it if the arch needs more than 24 ft of cover path; the wider 25 x 40 ft roll may fit better.

3

VEVOR 6 Mil Greenhouse Plastic Sheeting, 25x40 ft: Best for standard spans

8.6/10Our score

• 6 mil polyethylene
• 25 x 40 ft
• UV resistant
• Tear and weather resistance

The 25 x 40 ft roll is 6 mil clear polyethylene, with UV, tear and weather resistance stated. Check the required overlap and fastening area before cutting.

See it on Amazon

Pros

• 25 x 40 ft size
• 6 mil thickness
• UV and tear resistance

Cons

• No stated UV-resistance duration

VEVOR’s 25 x 40 ft roll matches the size of our top pick and uses 6 mil clear polyethylene. The brand states UV protection, tear resistance and weather resistance, but gives no UV-resistance duration.

That makes it a straightforward size to compare for a broad greenhouse cover. Measure the arch, sides and fastening area before deciding, since nominal width does not account for how much material the frame uses.

VEVOR describes the film for greenhouse and hoop-house coverage, along with other protective uses. Its size and thickness make it comparable with the Farm Plastic Supply option, which has a stated four-year UV-resistance period.

Choose it for a standard large cover when the size fits and UV protection without a stated duration suits your plans. Skip it if you need a stated service period; consider the Farm Plastic Supply roll instead.

4

VEVOR 6 Mil Greenhouse Plastic Sheeting, 24x50 ft: Best for extra length

8.3/10Our score

• 6 mil polyethylene
• 24 x 50 ft
• UV protected
• Can be folded into a roll

This 24 x 50 ft clear polyethylene roll is 6 mil thick and has UV protection stated. Compare the frame's widest point with the 24 ft sheet width before buying.

See it on Amazon

Pros

• 50 ft length
• 6 mil thickness
• UV protection

Cons

• No stated UV-resistance duration

This VEVOR roll measures 24 x 50 ft and is 6 mil clear polyethylene. The brand states UV protection, tear resistance and weather resistance, without naming a service period for its UV protection.

The 50 ft length suits longer structures, while the 24 ft width is slightly narrower than the 25 x 40 ft VEVOR roll. Compare both dimensions with the route over your frame and the material needed to secure the edges.

VEVOR says the film can be unfolded and folded back into rolls for storage. Keep unused material away from punctures and sharp edges.

Choose it for extra length when 24 ft of width is enough for the full cover path. Skip it for a compact frame that would leave a large surplus; the 20 x 28 ft roll may be easier to handle.

5

VEVOR 6 Mil Greenhouse Plastic Sheeting, 20x28 ft: Best for compact frames

8.0/10Our score

• 6 mil polyethylene
• 20 x 28 ft
• UV protected
• Can be folded into a roll

This 20 x 28 ft clear polyethylene roll is 6 mil thick and has UV protection stated. Map the roof, sides and fastening edges to confirm the sheet covers them all.

See it on Amazon

Pros

• 20 x 28 ft size
• 6 mil thickness
• UV protection

Cons

• May not cover larger frames in one piece

The VEVOR 20 x 28 ft roll is a 6 mil clear polyethylene option with UV protection stated. It may suit a compact greenhouse or limited replacement, depending on the structure’s shape and coverage needs.

Measure the full route the film must cover, including the curved roof, sides and attachment edges. A roll may sound wide but still fall short once the frame’s arch is included.

VEVOR says this film can be folded into rolls for storage. The brand also states tear and weather resistance, but gives no UV-resistance duration.

Choose it for a compact frame when 20 x 28 ft meets the measured need. Skip it for long growing rows or larger frames; its shorter length can leave those jobs short.

6

VEVOR 6 Mil Greenhouse Plastic Sheeting, 20x100 ft: Best for long crop rows

7.9/10Our score

• 6 mil polyethylene
• 20 x 100 ft
• UV protected
• Can be folded into a roll

This 20 x 100 ft clear polyethylene roll is 6 mil thick and has UV protection stated. Its 20 ft width is narrower than the larger-width rolls here, so check the arch and overlap needs.

See it on Amazon

Pros

• 100 ft length
• 6 mil thickness
• UV protection

Cons

• 20 ft width may not fit wider frames

This VEVOR sheet is 20 x 100 ft and 6 mil clear polyethylene. Its length suits a long greenhouse or several runs, while its 20 ft width may limit full coverage on wider arches.

VEVOR states UV, tear and weather resistance, but does not give a UV-resistance duration. Plan how often you can inspect outdoor film before making that claim a deciding factor.

The roll can be folded for storage, according to VEVOR. Before spreading it over a large span, set up a clear work area and arrange help so the film does not drag across sharp frame edges.

Choose it for long coverage runs that need up to 100 ft of material and no more than 20 ft of width. Skip it for a wide arch that needs more cover path, or for a small frame where handling a long roll adds hassle.

7

Farm Plastic Supply String-Reinforced 10 Mil Greenhouse Plastic: Best for narrow repairs

7.7/10Our score

• 10 mil string-reinforced polyethylene
• 4-year UV resistance
• 6 x 25 ft roll
• Clear film

This 10 mil film has heavy-duty string reinforcement laminated between polyethylene layers. The 6 x 25 ft roll is much smaller than the broad greenhouse-cover options, so verify its dimensions for your project.

See it on Amazon

Pros

• String reinforcement
• 10 mil thickness
• Stated 4-year UV resistance

Cons

• 6 ft width is too narrow for many full greenhouse covers

Farm Plastic Supply’s Dura Skrim combines polyethylene film with heavy-duty string reinforcement and has a stated 10 mil thickness. The brand states 4-year UV resistance, but the roll measures only 6 x 25 ft.

That narrow size changes how you can use it. It may fit a small section, repair project or limited application, but it is not a broad full-cover roll for most walk-in greenhouses.

Farm Plastic Supply describes the film as clear and says it allows light to pass through. Measure the specific area you need to cover before choosing it.

Choose it for a narrow area where string reinforcement matters. Skip it as a default full greenhouse cover; the 6 ft width is too limited for many frames.

8

Chicarry 6 Mil Greenhouse Film, 24x25 ft: Best for drip control

7.6/10Our score

• 6 mil polyethylene
• 24 x 25 ft
• Anti-drip additives
• Five-layer co-extrusion

This 24 x 25 ft, 6 mil polyethylene film has anti-drip additives. It offers broad width with less length than the larger rolls.

See it on Amazon

Pros

• Anti-drip additives
• 24 ft width
• 6 mil thickness

Cons

• 25 ft length may limit coverage on longer frames

Chicarry’s film measures 24 x 25 ft and is 6 mil polyethylene. The brand says it uses anti-drip additives intended to help droplets spread into a thin layer across the film.

The product is described as clear but may appear milky white. Its appearance and anti-drip feature distinguish it from the other clear options, so consider how you want light to look inside the greenhouse.

The 24 ft width gives this roll broad coverage, while its 25 ft length is shorter than the 40 ft and 50 ft rolls. Measure your frame, especially if the film must cover a long tunnel in one piece.

Choose it for a shorter, broad cover with anti-drip additives. Skip it for a long frame that needs more than 25 ft of film in one run.

9

VEVOR 6 Mil Greenhouse Plastic Sheeting, 10x100 ft: Best for narrow runs

7.5/10Our score

• 6 mil polyethylene
• 10 x 100 ft
• Diffused lighting effect
• Can be cut to size

This 10 x 100 ft, 6 mil polyethylene roll is described as having a diffused lighting effect and can be cut to size. It suits projects where 10 ft of width is enough, such as a long run or repair.

See it on Amazon

Pros

• 100 ft length
• Diffused lighting effect
• Can be cut to size

Cons

• 10 ft width limits full-cover use

VEVOR’s 10 x 100 ft film is a narrow, long 6 mil polyethylene roll. The brand describes its light as diffused, says the sheet can be cut to size, and names clips, wood strips and ground stakes as possible fastening methods.

At 10 ft wide, it may not cover many full greenhouse arches by itself. It can suit a narrow run, a patch or another project where the measured cover path stays within that width.

VEVOR says small holes or tears can be repaired with tape, sold separately. The brand does not state a UV-resistance duration, so include regular inspection in your care routine.

Choose it for a narrow, long project where the diffused lighting description fits your plans. Skip it for a full cover if the arch needs more than 10 ft of material across.

How to choose greenhouse plastic sheeting by size and use

Start with the frame measurements, then compare material features. Size determines whether the film can cover the whole structure; thickness, reinforcement and light details help narrow down suitable rolls.

Measure across the cover path from one lower attachment edge, over the roof, to the opposite edge. Measure the full length too, then add material for the ends, overlap and secure fastening.

Do not estimate from the floor dimensions alone. A high or wide arch needs more film than its footprint suggests, and a sheet with no extra material can be difficult to secure.

Next, think about the job. A 20 x 28 ft roll may suit a compact frame, while 24 x 50 ft and 20 x 100 ft options are shaped for longer runs; width still decides whether a sheet can cross the arch.

For a detailed size example, see how big a 10 x 10 greenhouse is. If you are choosing a structure as well as a cover, our backyard greenhouse guide compares greenhouse types and covers.

Is 6 mil or 10 mil greenhouse plastic better?

Six mil film offers more size choices in this group, while the 10 mil option adds string reinforcement and comes in a 6 x 25 ft roll. Choose based on coverage, reinforcement needs and how you plan to use the film.

Thickness does not determine fit by itself. A thicker sheet that is too narrow cannot cover the frame, and outdoor film still needs secure attachment to limit movement in wind.

The reinforced option suits a limited area where its construction matters more than broad coverage. For a larger greenhouse cover, most shoppers will find the wider 6 mil rolls easier to match to the frame.

For a closer comparison of common thicknesses, read 4 mil vs 6 mil greenhouse plastic. If you are deciding between polyethylene and another film type, our PE vs PVC greenhouse cover guide explains the material differences.

Should you choose clear, diffused or anti-drip film?

Clear film is the simple choice when you want light to pass through, while diffused film is described as spreading light more evenly. Chicarry’s film adds anti-drip additives, which are intended to spread water droplets into a thin layer.

The VEVOR 10 x 100 ft roll is described as having a diffused lighting effect. Chicarry’s 24 x 25 ft film is described as clear but may look milky white because of its anti-drip feature.

These descriptions help distinguish the options, but they do not replace a fit check. Consider your crop layout and sunlight pattern, then choose a roll with enough width and length for the frame.

How should greenhouse plastic be installed and cared for?

Install greenhouse film over a clean, smooth frame, then fasten it evenly using a method suited to the frame and cover. VEVOR names clips, wood strips and ground stakes as possible ways to secure its 10 x 100 ft film.

Before unrolling the cover, clear the work area and remove sharp edges that could puncture it. Plan where the seams and attachment points will go, then position helpers so the film does not drag across the ground or frame.

Pull the sheet evenly and leave enough material at the edges for secure fastening. Avoid stretching it hard across corners, but do not leave loose areas that can flap in wind.

After installation, check edges and seams after strong wind or heavy weather. Repair small damage promptly; VEVOR says tape can repair small holes or tears in its 10 x 100 ft film, with repair tape sold separately.

Keep unused film rolled and protected from punctures. If you are replacing an existing cover, follow our walk-in greenhouse cover replacement guide for a step-by-step plan.

What greenhouse plastic mistakes should you avoid?

The most common mistake is buying by footprint instead of measuring the full route over the frame. That can leave too little material for the roof, sides, end walls or fastening edges.

A second mistake is choosing thickness before checking width and length. The 10 mil reinforced roll is only 6 x 25 ft, so it suits limited areas better than many full greenhouse frames.

Avoid cutting the film before you have checked its position and attachment plan. Once trimmed, extra material cannot help with overlap or edge fastening.

Finally, do not assume a UV claim includes a set service period. Farm Plastic Supply states four years for its named options, while VEVOR states UV protection without a duration; use that difference when weighing replacement expectations.

Which greenhouse plastic sheeting should you choose?

Choose the Farm Plastic Supply 25 x 40 ft roll for a broad clear cover with stated 4-year UV resistance. Pick the 24 x 50 ft version for a longer structure, the 10 mil reinforced film for a narrow reinforced area, or the 20 x 28 ft roll for a compact frame.

If light spread or droplets are a priority, compare the VEVOR diffused-light roll and Chicarry’s anti-drip film after confirming their dimensions fit. Measure the curved cover path and allow for fastening before you choose any greenhouse plastic sheeting.

If your frame needs rigid panels instead of film, compare the options in our polycarbonate greenhouse panel guide.

Frequently asked questions

What thickness greenhouse plastic should I use?

Six mil is the common thickness among these picks. The 10 mil option adds string reinforcement, but its 6 x 25 ft size may not cover a full frame.

Choose by cover path and fastening needs first; thickness cannot make an undersized sheet fit.

How do I choose the right greenhouse plastic size?

Measure over the frame from one attachment edge, across the roof and down to the opposite edge, then measure the full length. Add material for fastening and overlap, then compare both measurements with the roll.

A floor footprint alone misses the curved roof.

Is UV-resistant greenhouse plastic worth choosing?

UV resistance matters when film stays outdoors in sunlight. Farm Plastic Supply states 4-year UV resistance on its two clear 6 mil rolls and reinforced film, while VEVOR states UV protection without a duration.

Follow the brand’s installation guidance.

Should greenhouse plastic be clear or diffused?

Clear film lets light pass through, while diffused light spreads it more evenly across the growing space. VEVOR describes its 10 x 100 ft option as having a diffused lighting effect.

Choose based on your plants, frame and sunlight pattern.

How do I keep greenhouse plastic from tearing?

Smooth sharp edges on the frame, pull the film evenly, and use a fastening method suited to the frame and film. Leave enough slack for attachment without loose areas that flap.

Inspect seams and edges after storms so small tears do not spread.
