A strong 6 mil greenhouse film combines a workable sheet size with outdoor protection suited to your structure, making it a practical choice for growers covering everything from compact tunnels to full greenhouses. Farm Plastic Supply Clear Greenhouse Plastic Sheeting stands out for its 25-by-40-foot format, stated four-year UV resistance, and greater than 90% light transmittance. This roundup compares ten products that all list 6 mil thickness, but they differ substantially in dimensions, stated UV features, and how specifically they are presented for greenhouse use.
Some are purpose-built greenhouse films; others are general plastic sheeting or smaller covers. Check your structure’s coverage needs before choosing: the largest roll is not automatically the best fit, and the listed product information does not establish how any film performs after installation.
Farm Plastic Supply Clear Greenhouse Plastic Sheeting is the best overall choice in this group because it is explicitly made as 6 mil clear greenhouse film, measures 25 by 40 feet, and lists four-year UV resistance plus greater than 90% light transmittance. That combination makes it a strong fit for growers who need broad coverage and stated outdoor-use features. If you need a different sheet size, compare the 10-by-100-foot VEVOR film or the 10-by-50-foot chicarry film against your structure’s measurements.

Detailed Reviews: Best 6 Mil Plastic For Greenhouse

#1 · Best Overall
1. Farm Plastic Supply Greenhouse Film
- Size: 25'W x 40'L
- Weight: 30 lb
- Dimensions: 480"L x 300"W x 100"H
Best for: Multi-year UV-rated greenhouse film.
Why it ranks #1: Purpose-made 6 mil greenhouse film measures 25 by 40 feet and lists four-year UV resistance with greater than 90% light transmittance.
A stated four-year UV-resistance rating distinguishes this 6 mil clear Farm Plastic Supply film for growers planning a longer-term greenhouse cover. The 25-by-40-foot polyethylene sheet pairs that rating with greater than 90% light transmittance, supporting a sizeable covered growing area while allowing substantial light through.
The 25-foot width and 40-foot length provide a large sheet for greenhouse, hoop-house, or farm coverage, while the 6 mil polyethylene construction is described as tough and durable. Anti-aging UV additives are specified to protect the film from UV rays and prolong its life, and the four-year UV-resistance rating gives a concrete planning horizon. Greater than 90% light transmittance is relevant when choosing a clear cover for growing areas that need incoming light. The product is listed for gardening, farming, and agriculture.
- 25-by-40-foot sheet for broad coverage
- 6 mil polyethylene film
- Four-year UV-resistance rating with anti-aging additives
- Greater than 90% light transmittance
- The 25-foot width can be cumbersome to position on smaller structures.
Skip it if you need a 10-foot-wide roll for a narrower run; VEVOR's 10-by-100-foot film offers that width.
A good fit for growers planning a substantial greenhouse or agricultural cover who want a stated UV-resistance period and high light transmittance. Account for the 25-foot width when moving and positioning the sheet.

#2 · Layered Film
2. AGGAFA Greenhouse Plastic
- Size: 6mil-10ftx15ft
Best for: Small greenhouse with anti-fog film.
Why it ranks #2: This 6 mil greenhouse film uses five-layer extrusion and lists UV protection, anti-drip, anti-fog, thermal features, and four-year UV resistance.
Five-layer extrusion combines UV protection, anti-drip, anti-fog, thermal properties, and strength in AGGAFA’s 6 mil, 10-by-15-foot polyethylene film. Its specified light distribution and heat-retention role make it a feature-rich option for a smaller greenhouse cover, with a stated four-year UV-resistance lifetime in the title.
The 10-by-15-foot sheet is suited to a limited greenhouse area, while 100% raw-material polyethylene and five-layer extrusion are specified for strength and protective features. AGGAFA lists UV protection, anti-drip, anti-fog, and thermal properties, which address several conditions growers may consider when selecting a cover. The description also says sunlight passes through and distributes evenly, supporting more even temperature distribution, and says the film can keep warmth in cold temperatures. The title states a four-year UV-resistant lifetime.
- 10-by-15-foot sheet for smaller coverage
- 6 mil polyethylene using 100% raw materials
- Five-layer extrusion with anti-drip and anti-fog features
- Four-year UV-resistant lifetime stated in the title
- The 15-foot length limits use on larger greenhouse structures.
Skip it if you need a longer continuous sheet; VEVOR's 10-by-100-foot film offers far more length at the same listed width.
AGGAFA fits growers covering a smaller greenhouse area who value anti-fog, anti-drip, thermal, and UV features in one film. Its 10-by-15-foot dimensions are a limiting factor for larger structures.

#3 · Large Sheet
3. chicarry Greenhouse Film
- Size: 10 x 50ft
- Weight: 5.13 kg
Best for: Large flexible greenhouse covers.
Why it ranks #3: The 10-by-50-foot clear polyethylene sheet is 6 mil, uses five-layer co-extrusion, and lists UV resistance and anti-drip features.
Five-layer co-extrusion gives this 6 mil polyethylene film mechanical strength and flexibility across a 10-by-50-foot sheet. That combination supports covering a substantial greenhouse area while making the material more adaptable during installation. UV resistance and an anti-drip feature add protection-related benefits for growers seeking a clear, heavy-duty cover.
The 10-foot width and 50-foot length provide a continuous sheet for larger greenhouse or garden-covering projects, while the polyethylene construction keeps the material flexible to handle. Its five-layer co-extrusion is specified for high mechanical strength and flexibility, which supports sturdier coverage without giving up workability. The film is also described as UV resistant and tear resistant, and its anti-drip feature may suit growers concerned about moisture on the covering. Wear gloves when handling it, as the safety information warns of sharp edges.
- 10-by-50-foot sheet covers a broad area
- 6 mil polyethylene film
- Five-layer co-extrusion combines strength and flexibility
- UV resistant, tear resistant, and anti-drip
- The supplied details do not specify a UV-resistance lifetime.
Skip it if you need a stated multi-year UV rating; Farm Plastic Supply's 25-by-40-foot film specifies four years of UV resistance.
Choose this sheet for a larger greenhouse cover where broad dimensions, flexibility, and the listed anti-drip feature matter. Its 10-by-50-foot format and handling weight call for planning the installation, and no UV-resistance duration is stated.

#4 · Longest Roll
4. VEVOR Greenhouse Sheeting
- Weight: 30.9 lb
- Dimensions: 34.45 x 7.09 x 7.09 in
Best for: Long hoop-house coverage.
Why it ranks #4: Its 10-by-100-foot, 6 mil polyethylene film offers the longest listed roll and is described for greenhouse, hoop-house, or garden-bed coverage.
A 10-by-100-foot roll of 6 mil polyethylene gives VEVOR growers an unusually long continuous sheet for greenhouses, hoop houses, or garden beds. Its thick yet flexible construction is specified to reduce tearing and punctures during installation, while the listed outdoor protection addresses sun, wind, rain, frost, and low temperatures.
The 100-foot length can cover extended structures or beds with fewer separate pieces than a shorter sheet, and the 10-foot width defines the span each run can cover. VEVOR describes the 6 mil polyethylene as both thick and flexible, a combination intended to help during installation by reducing tearing and punctures. The film is also listed for exposure to harsh sun, wind, rain, frost, and low temperatures. Its even-light-distribution feature supports a more consistent light environment for covered plants.
- 10-by-100-foot continuous coverage
- 6 mil polyethylene construction
- Thick yet flexible to reduce installation tears and punctures
- Listed for sun, wind, rain, frost, and low temperatures
- The 10-foot width may require joined runs for structures wider than the sheet.
Skip it if you need only a small patch; warmfarm's 6.5-by-9.8-foot sheet is a more compact format.
This suits growers covering long hoop houses, greenhouses, or garden beds who value a continuous 100-foot run and outdoor-weather coverage. Check the 10-foot width against the structure before planning the layout.

#5 · Light Transmission
5. PROMORE Greenhouse Plastic
- Size: 10×25 FT
- Weight: 5.16 lb
- Dimensions: 300 x 120 x 0.01 in
Best for: Light-transmitting LDPE cover.
Why it ranks #5: This 10-by-25-foot, 6 mil LDPE film lists over 90% light transmission and UV blockers filtering out over 20% of harmful rays.
PROMORE specifies greater than 90% natural-light transmission for this 10-by-25-foot, 6 mil greenhouse sheet, a useful detail for growers choosing a clear cover. Its industrial-grade LDPE is described as tough and tear resistant, while built-in UV blockers filter out over 20% of harmful rays and help prevent film degradation.
The 10-by-25-foot format suits a smaller greenhouse section or a defined covering project, and the clear LDPE construction is specified to transmit more than 90% of natural light. That light-transmission figure helps buyers assess the film for plant coverage rather than relying on appearance alone. PROMORE also lists built-in UV blockers that filter out over 20% of harmful rays and help prevent degradation. The 6 mil thickness and tear-resistant material support handling for demanding protection, though the stated sheet length limits a single run.
- 10-by-25-foot clear sheet
- 6 mil industrial-grade LDPE
- Transmits over 90% of natural light
- UV blockers filter out over 20% of harmful rays
- The 25-foot length is limiting for long, continuous greenhouse runs.
Skip it if you need more than 25 feet in one run; VEVOR's 10-by-100-foot sheet offers substantially longer coverage.
This fits growers who need a compact clear cover and value stated light transmission alongside UV blocking. Use the 10-by-25-foot dimensions to check the planned run; longer structures call for a longer sheet.

6. Legigo Greenhouse Plastic
- Weight: 9.5 lb
- Dimensions: 13.2 x 2.7 x 16 in
Best for: Winter plant-covering projects.
Why it ranks #6: The 10-by-50-foot, 6 mil polyethylene sheet is presented for plant and freeze protection, with clear film described as allowing sunlight through.
Legigo supplies a 10-by-50-foot, 6 mil clear polyethylene sheet specifically described for plant coverage and winter freeze protection. The generous length can serve as a growing-area cover or an extra protective layer, while the clear film is said to let sunlight reach plants and retain heat to help keep them warm.
The 10-by-50-foot dimensions provide a long sheet for a winter growing area or extra plant protection, and the 6 mil polyethylene is described as strong, tough, and heavy duty. Legigo contrasts clear sheeting with polypropylene fabric, noting that its film lets sunlight reach plants and retains heat to keep them warm through winter. Those properties support the stated freeze-protection use. The description does not specify a UV-resistance duration, so buyers should focus on the listed winter-covering role and the required sheet dimensions.
- 10-by-50-foot sheet for broad plant coverage
- 6 mil polyethylene
- Clear film lets sunlight reach plants
- Described to retain heat for winter plant protection
- No UV-resistance duration is specified in the supplied details.
Skip it if you need a stated multi-year UV rating; Farm Plastic Supply's 25-by-40-foot film lists four years of resistance.
Legigo suits growers seeking a long clear sheet for winter plant coverage or an extra protective layer. Its stated benefits center on sunlight and heat retention, while no UV-resistance lifetime is supplied.

7. Axgatoxe Greenhouse Sheeting
- Weight: 5.88 lb
- Dimensions: 300 x 120 x 0.1 in
Best for: Small greenhouse and project cover.
Why it ranks #7: This 10-by-25-foot, 6 mil sheet is described as a UV-resistant greenhouse cover, though its listing also emphasizes drop-cloth and construction uses.
At 10 by 25 feet, this 6 mil Axgatoxe polyethylene sheet offers a manageable format for smaller greenhouse covers and temporary protection jobs. Its listed UV resistance and tear-proof greenhouse-cover description suit outdoor plant coverage, while the product information also identifies uses as a drop cloth, tarp, and temporary floor covering.
The 10-by-25-foot size is suited to a compact greenhouse run or a defined work area, rather than requiring a longer sheet to be handled for every project. Axgatoxe identifies the 6 mil industrial-grade polyethylene as heavy duty and describes the greenhouse-cover use as UV resistant and tear-proof. The same sheet is also presented for protecting floors, furniture, and equipment during painting or construction, giving it uses beyond plant coverage. Its product description therefore supports keeping it available for both garden and messy home projects.
- 10-by-25-foot sheet for compact coverage
- 6 mil polyethylene
- Listed as UV resistant and tear-proof for greenhouse use
- Also described for drop-cloth and temporary floor-covering tasks
- The 25-foot length limits coverage for longer greenhouse runs.
Skip it if you need a continuous 50-foot greenhouse cover; chicarry's 10-by-50-foot film provides twice the stated length.
Consider this sheet for a smaller greenhouse, a defined plant-covering area, or occasional painting and construction protection. The 10-by-25-foot dimensions are the key boundary if your structure needs a longer continuous run.

8. warmfarm Greenhouse Film
- Weight: 1.43 lb
- Dimensions: 117.6 x 78 x 0.1 in
Best for: Mini-greenhouse and tunnel patches.
Why it ranks #8: The 6 mil polyethylene film suits small tunnels or mini greenhouses, but its 6.5-by-9.8-foot dimensions limit coverage compared with larger rolls.
At 6.5 feet wide by 9.8 feet long, warmfarm’s 6 mil clear polyethylene film is a compact option for planting tunnels, mini greenhouses, and specific garden blocks. Its flexible, tear-resistant construction supports unfolding and installation as a small covering, without requiring a full-size greenhouse roll.
The 6.5-by-9.8-foot dimensions are well suited to a defined patch or small structure, and the 6 mil polyethylene is described as flexible and tear resistant. The product details specifically name planting tunnels, mini greenhouses, and vegetable and flower blocks as uses, giving buyers concrete ways to apply the compact sheet. Its clear film is presented as greenhouse covering, but the supplied facts do not give a UV-resistance rating or light-transmission figure. That makes size and simple coverage the strongest supported selection points.
- Compact 6.5-by-9.8-foot dimensions
- 6 mil polyethylene film
- Flexible and tear resistant
- Listed for tunnels, mini greenhouses, and garden blocks
- The 9.8-foot length is too short for covering a full-size greenhouse run.
Skip it if you need a long greenhouse covering; chicarry's 10-by-50-foot sheet provides substantially more length and width.
Pick this for a mini greenhouse, planting tunnel, or small vegetable or flower block where a compact sheet is enough. Its 6.5-by-9.8-foot dimensions are the main boundary for larger coverage.

9. Tapix Plastic Sheeting
- Size: 1 Roll
- Weight: 7.02 lb
- Dimensions: 10 x 4 x 4 in
Best for: Greenhouse and jobsite utility.
Why it ranks #9: This 10-by-25-foot, 6 mil clear sheeting lists UV protection, but its product description focuses mainly on construction, painting, and general protection.
Tapix pairs a 10-by-25-foot, 6 mil polyethylene sheet with multiple listed uses, from greenhouse film to protection for floors, walls, equipment, and construction materials. Its outdoor UV protection is specified to resist sun damage and cracking, giving this multipurpose roll relevance beyond a single gardening season or task.
The 10-by-25-foot size provides a defined sheet for smaller greenhouse sections and home-improvement jobs, while the 6 mil construction is described as heavy duty and resistant to tearing. Tapix also lists it as a drop cloth for shielding floors, walls, equipment, and materials from dust, paint, and debris. For outdoor use, the supplied facts say UV protection resists sun damage to prevent cracking and extend outdoor-use lifespan. Those combined applications make it useful to store for both garden coverage and messy projects.
- 10-by-25-foot sheet
- 6 mil polyethylene described as tear resistant
- Listed for greenhouse film and multipurpose protection
- UV protection resists sun damage and cracking
- The listed size is too short for greenhouse runs longer than 25 feet.
Skip it if you need a longer continuous sheet; Legigo's 10-by-50-foot cover gives twice the listed length.
Choose Tapix if you want one 10-by-25-foot sheet for a small greenhouse area and household or construction protection. Its varied uses are useful, but the stated dimensions set a clear limit for larger structures.

10. Frost King Polyethylene Sheeting
- Size: 10' x 25' x 6 mil
Best for: General-purpose garden and home cover.
Why it ranks #10: The 10-by-25-foot, 6 mil clear sheet can cover plants, but its listed uses are general household and outdoor protection rather than greenhouse film.
Frost King’s 10-by-25-foot, 6 mil clear polyethylene sheet is listed for an unusually broad range of covering tasks, including plants, shrubs, furniture, appliances, and outdoor-stored equipment. That versatility makes it a practical option for buyers who need general-purpose sheeting as well as occasional garden coverage.
The 10-by-25-foot sheet offers a defined coverage area for plants or shrubs and for protecting furniture, appliances, and equipment around the home or garage. Frost King also lists uses as a moisture barrier, temporary enclosure, boat cover, and protection for building materials and machinery stored outdoors. Its clear polyethylene construction and 6 mil thickness are specified, but the supplied facts do not state a greenhouse-specific UV rating or light-transmission figure. Buyers prioritizing those greenhouse performance details should weigh that information gap.
- 10-by-25-foot clear polyethylene sheet
- 6 mil thickness
- Listed for covering plants and shrubs
- Also usable for temporary enclosures and outdoor-stored items
- No greenhouse-specific UV-resistance rating or light-transmission figure is supplied.
Skip it if you require a stated UV duration for greenhouse use; Farm Plastic Supply's film specifies four years of UV resistance.
This is suitable for buyers who want clear sheeting for occasional plant coverage alongside home, garage, and outdoor-protection tasks. For a permanent greenhouse setup, note that no UV-resistance duration or light-transmission figure is provided.

View on AmazonAvoiding tears at greenhouse edges and fasteners
A 6 mil label alone does not guarantee that a sheet will stay intact at attachment points; fit and handling matter too. Several listings describe tear resistance or toughness, including chicarry’s five-layer co-extrusion film and Legigo’s heavy-duty polyethylene, but none supplies a fastening method or tear-test result. Measure the frame and allow enough material to reach the attachment points without stretching the film taut.
Sharp frame edges and concentrated pressure around fasteners can damage plastic, so smooth contact surfaces and distribute tension rather than pulling hard at one point. The chicarry listing also advises wearing gloves when handling the sheet.
Treat UV resistance claims as distinct from tear resistance: Farm Plastic Supply specifies four-year UV resistance, while that statement does not establish how long the film will withstand wind, abrasion, or installation stress. Plan to inspect edges and attachment areas after installation and following severe weather.
Match the roll to the structure, not just the footprint
A roll’s listed width and length do not directly equal the greenhouse floor area it can cover, because the roof and sides also require material. For a straightforward example, chicarry lists a 10-by-50-foot sheet, while Farm Plastic Supply lists 25 by 40 feet and VEVOR lists 10 by 100 feet. Their total sheet areas differ, but a narrow roll may require seams on a wide structure, and a longer roll may still be the wrong shape for the frame.
Include the roof curve, side walls, end walls, overlap at seams, and material needed to secure the edges when estimating coverage. The 6.5-by-9.8-foot warmfarm film is listed for small tunnels and mini greenhouses, illustrating that a compact sheet may suit a small cover better than a full structure.
Product listings do not specify every roll’s usable dimensions after trimming, so confirm the actual layout before ordering.
How to Choose 6 Mil Greenhouse Plastic
Sheet dimensions and coverage
Start by matching the listed sheet dimensions to the full surface you intend to cover, not just the greenhouse floor. The options range from warmfarm at 6.5 by 9.8 feet and AGGAFA at 10 by 15 feet to several 10-by-25-foot rolls, chicarry and Legigo at 10 by 50 feet, Farm Plastic Supply at 25 by 40 feet, and VEVOR at 10 by 100 feet. A compact tunnel may favor warmfarm; a long, narrow structure may suit VEVOR’s 100-foot length.
Farm Plastic Supply’s 25-foot width may better suit a wider layout. Account for roof curvature, sides, end walls, and overlap before selecting a roll; the listed dimensions alone do not establish fit for a particular frame.
UV and greenhouse-specific features
Look for an explicitly stated outdoor or greenhouse feature that matches how long you plan to leave the cover in place. Farm Plastic Supply lists four-year UV resistance, and AGGAFA also lists a four-year UV-resistant lifetime alongside five-layer extrusion, anti-drip, and anti-fog features. chicarry describes UV resistance and anti-drip performance, while PROMORE lists UV blockers that filter out over 20% of harmful rays.
These descriptions are not identical guarantees, so do not treat them as interchangeable service-life claims. For a long-term greenhouse cover, the stated UV duration on Farm Plastic Supply or AGGAFA is a useful differentiator.
For buyers prioritizing a range of listed film features, AGGAFA’s additional anti-drip and anti-fog claims may matter; confirm that its 10-by-15-foot size covers the intended structure.
Light transmission and film purpose
Check the product’s stated light information and whether the listing is actually centered on greenhouse growing. Farm Plastic Supply specifies greater than 90% light transmittance, and PROMORE lists over 90% natural light transmission; chicarry and AGGAFA describe light distribution or transmission without the same percentage in the supplied details. VEVOR describes its film as combining protection and light transmission but provides no percentage here.
General-purpose sheets such as Tapix and Frost King list household, construction, or protective uses, so their 6 mil thickness alone does not make them equivalent to a greenhouse-specific film. Buyers who need a stated transmission figure can favor Farm Plastic Supply or PROMORE.
Those choosing a general cover for temporary use may consider broader-use sheets, while verifying suitability for their growing conditions.
Which 6 Mil Greenhouse Plastic Should You Choose?
For a broad greenhouse cover with stated UV life and light transmission, choose Farm Plastic Supply Greenhouse Film: its 25-by-40-foot size, four-year UV resistance, and greater than 90% light transmittance make it the strongest all-around match. If you want several stated film features in a smaller roll, AGGAFA Greenhouse Plastic lists five-layer extrusion, anti-drip, anti-fog, and four-year UV resistance in a 10-by-15-foot size. For a 10-foot-wide cover with more length, chicarry Greenhouse Film offers 50 feet and lists UV resistance and anti-drip features; VEVOR Greenhouse Sheeting extends to 100 feet.
PROMORE Greenhouse Plastic is another 10-by-25-foot option with over 90% light transmission. For a small tunnel, consider warmfarm Greenhouse Film.
Measure the full structure before deciding.

Frequently Asked Questions
How should greenhouse plastic be attached to a frame without tearing?
Secure the film with greenhouse clips or battens that spread pressure along the frame, rather than relying on a few tight fasteners. Keep the sheet evenly tensioned but not overstretched, and smooth sharp edges or corners that could abrade it. Follow the film and frame manufacturers’ fastening guidance where available.
Does greenhouse plastic need to be removed or replaced seasonally?
Not necessarily; removal or replacement depends on the film’s stated UV resistance, local weather, and its condition. Inspect for tears, brittleness, loose attachment, and reduced clarity, especially after severe weather. Repair small damage when appropriate, and replace the cover when it no longer provides reliable protection or light for your growing needs.
How do I calculate the sheet size needed for a greenhouse roof and sides?
Measure the roof over its full curved or sloped surface, not just the greenhouse’s ground width. Add the side drops, then measure the structure’s length. Include extra material for anchoring and any overlaps between sections.
Compare those totals with the sheet’s width and length before choosing a roll or cover.
Which film details should I compare before choosing a cover?
Start with sheet dimensions and confirm they fit your measured structure. Then compare stated features relevant to your use, such as UV resistance, light transmission, anti-drip, or anti-fog properties. Product listings vary in how much detail they provide, so avoid assuming a feature is present unless it is explicitly stated.
When is a smaller greenhouse film sheet a practical choice?
A smaller sheet can suit a small tunnel, a limited covering area, or a repair, provided its dimensions cover the intended surface with enough material for attachment. Measure the full roof and sides first, and account for overlaps if joining pieces. A sheet that is too small may leave gaps or require additional seams.
Final Words
Measure the roof, sides, and attachment allowance before choosing among these sheets. For broad coverage with stated UV resistance and light-transmission information, Farm Plastic Supply is the strongest all-around match in this group. Consider VEVOR or chicarry when their longer 10-foot-wide rolls better suit your dimensions, and AGGAFA when its listed film features fit your needs.
For smaller structures, compare the compact options carefully; the right fit matters as much as the listed features.
