Best Poly Film For Greenhouse: Compare 6 Mil Covers

#1 · Best Overall

1. Farm Plastic Supply 4 Year 6 Mil Film

• Size: 16' x 10'
• Weight: 30 lb
• Dimensions: 10"L x 10"W x 40"H

Best for: UV-treated clear film buyers.

Why it ranks #1: Purpose-made clear greenhouse polyethylene has anti-aging UV additives, a stated four-year design, and 6 mil thickness; its 16-by-10-foot sheet is compact.

Anti-aging UV additives give this Farm Plastic Supply film a stated four-year greenhouse-cover lifespan, making it a focused choice for growers seeking longer-term clear sheeting. The 6-mil polyethylene film measures 16 by 10 feet and is described as transmitting light for greenhouse use.

The 6-mil polyethylene construction provides a tough cover, while anti-aging UV additives protect the film from UV rays and are intended to prolong its service life. Clear sheeting and the stated light transmission support use where plants need light through the greenhouse cover. At 16 by 10 feet, it fits a defined area rather than a large house in one piece. The listed 30-pound weight is worth factoring into handling, especially when positioning or cutting the sheet.

Skip it if you need a much larger sheet in one piece; VEVOR's 25-by-40-foot greenhouse film provides broader coverage.

Consider this Farm Plastic Supply film for a defined greenhouse section where clear, UV-treated 6-mil sheeting and a stated four-year lifespan match the plan. Its 16-by-10-foot dimensions and listed 30-pound weight are important handling and coverage boundaries.

#2 · Largest Clear Sheet

2. VEVOR 25 x 40 ft Greenhouse Film

• Size: 25 x 40 ft
• Weight: 28.7 lb
• Dimensions: 480"L x 300"W x 0.01"H

Best for: Large hoop-house coverage.

Why it ranks #2: This greenhouse-specific 6 mil UV-resistant polyethylene measures 25 by 40 feet, making it the strongest listed fit for covering a larger structure.

A 25-by-40-foot sheet gives VEVOR’s 6-mil polyethylene film broad coverage for hoop greenhouses, farms, and gardens. Its UV resistance and tear-resistant construction support outdoor greenhouse use, while the clear film is specified to help maintain warm temperatures in hot conditions.

The 25-foot width and 40-foot length can cover a substantial greenhouse area with one sheet, and the product description says the film unfolds quickly and can be folded into rolls. Its 6-mil polyethylene construction is tear-resistant, supporting use on hoop houses and agricultural structures. UV resistance is specified for hot temperatures, with the film intended to help maintain warmth. The large dimensions suit broad coverage, but require planning for handling and installation.

Skip it if you need a 10-by-25-foot sheet for a smaller cover; Tapix's 6-mil roll has those dimensions.

This VEVOR sheet suits growers covering a large hoop house or agricultural area who can manage a 25-by-40-foot film during installation. Its 6-mil thickness and UV resistance fit outdoor use, while the broad dimensions may exceed smaller projects.

#3 · Four-Year Design

3. SUNVIEW 6 Mil Greenhouse Film

• Size: 12ft. X 25ft.
• Weight: 2 lb

Best for: Four-year light-transmitting cover.

Why it ranks #3: The clear 12-by-25-foot polyethylene film is UV treated and lists a four-year guarantee, with higher light transmission described for plant growth.

Higher light transmission is the defining feature of this clear SUNVIEW film, supporting photosynthesis beneath a greenhouse cover. The 6-mil low-density polyethylene sheet measures 12 by 25 feet, is UV treated, and carries a stated four-year guarantee for greenhouse use.

The clear low-density polyethylene film is described as having higher light transmission, a practical fit for growers who want daylight to reach plants through the cover. Its 6-mil thickness, strength, and toughness support covering a greenhouse, while UV treatment and weather resistance address outdoor exposure. The 12-by-25-foot size gives a defined coverage area, and the stated four-year guarantee is a useful lifespan reference. Buyers should match that sheet size to the structure before installation.

Skip it if you need a 25-by-40-foot sheet for broad coverage; VEVOR's greenhouse film lists those larger dimensions.

This SUNVIEW cover fits growers prioritizing light transmission and UV-treated, 6-mil film for a 12-by-25-foot area. Its stated four-year guarantee adds a lifespan reference, but the sheet dimensions limit its suitability for larger structures.

#4 · High Light Transmission

4. PROMORE 12 x 25 ft 6 Mil Film

• Size: 12×25 FT
• Weight: 6.45 lb
• Dimensions: 300 x 144 x 0.01 in

Best for: High-light-transmission covers.

Why it ranks #4: This clear 6 mil LDPE sheet is sized 12 by 25 feet and lists more than 90% natural-light transmission alongside UV blockers.

More than 90% natural-light transmission is the key specification of this PROMORE greenhouse film, supporting bright conditions beneath its clear cover. The 6-mil, 12-by-25-foot low-density polyethylene sheet also lists UV blockers that filter over 20% of harmful rays.

The LDPE film is described as industrial grade and tear resistant, which supports use as heavy-duty greenhouse sheeting. Its stated transmission of over 90% of natural light is relevant when sunlight through the cover matters, while UV blockers filtering over 20% of harmful rays address exposure and film degradation. At 12 by 25 feet, it covers a defined area. Those quantified light and UV specifications help buyers compare it with films whose listing gives no comparable percentages.

Skip it if you need a 25-by-40-foot sheet for a larger greenhouse; VEVOR's film lists those dimensions.

This PROMORE sheet suits growers prioritizing stated light transmission and UV-filtering figures in a 6-mil cover. Its 12-by-25-foot dimensions fit a defined area, so larger structures may require a different sheet size or additional coverage.

5. chicarry 24 x 25 ft Greenhouse Film

• Weight: 6.35 kg

Best for: Wide greenhouse cover projects.

Why it ranks #5: The 24-by-25-foot, 6 mil polyethylene cover is explicitly intended for greenhouses and lists UV resistance and five-layer co-extrusion.

A 24-foot width gives this chicarry greenhouse film substantial coverage across a structure, with 25 feet of length in the listed sheet. Its 6-mil polyethylene uses five-layer co-extrusion technology, and the product description specifies UV resistance and tear resistance for outdoor covering.

The 24-by-25-foot format offers a broad sheet for greenhouse projects, while 6-mil polyethylene supplies the stated film thickness. Five-layer co-extrusion technology is described as providing mechanical strength and flexibility, supporting a cover that must span a structure. UV and tear resistance are also specified for outdoor use. The title calls the film clear, but the specifications list its color as white, so buyers should account for that description discrepancy when selecting a cover.

Skip it if you require an unambiguous clear-film listing; SUNVIEW's 12-by-25-foot cover is explicitly described as clear.

This chicarry sheet suits projects needing a wide, 6-mil polyethylene cover with stated UV and tear resistance. The 24-by-25-foot dimensions offer broad coverage, but the title and specifications disagree about whether the film is clear or white.

6. Axgatoxe 10 x 25 ft 6 Mil Film

• Weight: 5.88 lb
• Dimensions: 300 x 120 x 0.1 in

Best for: Heavy-duty 10-by-25 covers.

Why it ranks #6: Its 6 mil polyethylene sheet measures 10 by 25 feet and is described as a UV-resistant, tear-resistant greenhouse cover, though it is also multipurpose sheeting.

Six-mil industrial-grade polyethylene gives this Axgatoxe 10-by-25-foot sheet a heavy-duty profile for greenhouse covering and protection around home projects. Its listing specifies UV resistance and tear resistance, with uses extending to floors, furniture, and equipment during painting or construction.

The 6-mil polyethylene thickness is presented for heavy-duty protection, while tear resistance supports use as a greenhouse cover or temporary tarp. UV resistance is also specified for shielding plants from harsh sunlight and rain. The 10-by-25-foot sheet can serve greenhouse coverage as well as protect floors, furniture, or equipment during messy work, making it useful across projects. Its defined dimensions suit a particular area, so buyers planning a larger cover should account for the sheet size.

Skip it if you need a 25-by-40-foot sheet to cover a large structure; VEVOR's greenhouse film lists that larger size.

Consider Axgatoxe for a 10-by-25-foot greenhouse cover that can also protect floors, furniture, or equipment during project work. Its 6-mil thickness and UV resistance suit outdoor use, but the listed dimensions set the coverage boundary.

7. Tapix 10 x 25 ft 6 Mil Sheeting

• Size: 1 Roll
• Weight: 7.02 lb
• Dimensions: 10 x 4 x 4 in

Best for: Small greenhouse repair cover.

Why it ranks #7: This 6 mil, 10-by-25-foot clear polyethylene sheeting has verified UV protection, but its stated uses emphasize construction and painting rather than greenhouse growing.

Six-mil polyethylene in a 10-by-25-foot sheet gives this Tapix roll a useful combination of thickness and manageable coverage. Its UV protection supports outdoor use, while the same sheeting can cover greenhouse surfaces or protect floors, walls, tools, and materials during painting and construction work.

The 6-mil material is described as tear-resistant, so it can provide substantial coverage for demanding projects. UV protection helps it resist sun damage and cracking during outdoor use, making it relevant for a greenhouse cover as well as temporary protection around the home. At 10 by 25 feet, the sheet suits a defined area rather than a very large structure. Its multipurpose use can also make one roll useful for painting and construction cleanup.

Skip it if you need a 25-by-40-foot sheet for a larger structure; VEVOR's greenhouse film provides that listed size.

Choose this Tapix roll for a smaller greenhouse area or for projects that also need protection from paint, dust, and debris. Its 10-by-25-foot dimensions set a clear limit on how much structure one sheet can cover.

#8

8. Farm Plastic Supply Panda Film

• Size: 30' x 75'
• Weight: 10 lb

Best for: Light-deprivation growers.

Why it ranks #8: The 6 mil, 30-by-75-foot black-and-white film serves a specialized light-deprivation role, not the clear light-transmitting cover most greenhouse buyers need.

A black side and a white side make this Farm Plastic Supply Panda Film a reversible blackout cover for light-deprivation growing. The 6-mil sheet is 30 by 75 feet, with the black side creating darkness and the white exterior reflecting light away from the greenhouse.

The product is engineered to provide complete darkness, making it a specialized choice for growers who need to block light rather than transmit it to plants. Its reversible black-and-white construction lets the black side face inward for blackout conditions while the white exterior reflects light. The 30-by-75-foot dimensions cover a large area, and UV protection is specified. This is a distinct alternative to clear greenhouse film, so its light-blocking function should match the growing workflow.

Skip it if you need daylight to pass through a conventional cover; Farm Plastic Supply's 16-by-10-foot clear film is a better fit.

This Panda Film suits growers using light deprivation across a large greenhouse area, especially when the reversible black-and-white sides fit the setup. It is not a clear daylight-transmitting cover, so its blackout purpose must match the crop workflow.

#9

9. Tapix 10 x 25 ft 3 Mil Sheeting

• Size: 10 feet x 25 feet

Best for: Multipurpose two-roll projects.

Why it ranks #9: This two-roll offering is UV-protected and lists greenhouse use, but its 3 mil thickness is lighter than the 6 mil greenhouse films ranked above.

Two 10-by-25-foot rolls give this Tapix 3-mil polyethylene sheeting flexible coverage for greenhouse, painting, construction, and moisture-barrier tasks. UV inhibitors help the film resist sun damage and degradation outdoors, making it a lighter-thickness option for buyers who value multipurpose use.

Each roll measures 10 by 25 feet, so the two-pack provides separate sheets for different areas or projects. The 3-mil polyethylene is specified for greenhouse covers as well as construction, painting, and moisture barriers, while UV inhibitors support outdoor use by resisting sun damage and degradation. That combination makes the pack useful beyond a single greenhouse application. Its listed 3-mil thickness is less than the 6-mil options, so the thickness should suit the intended covering demands.

Skip it if you need 6-mil sheeting for a thicker cover; Tapix's 10-by-25-foot 6-mil roll offers that specification.

Choose this Tapix two-pack for multipurpose projects that can use 3-mil polyethylene across greenhouse, painting, or construction tasks. It offers two separately sized rolls, but the thinner film may not suit buyers seeking the listed 6-mil thickness.

10. Ansgery 14 x 20 ft 16 Mil Tarp

• Size: 14X20FT,16Mil
• Dimensions: 1"L x 1"W

Best for: Reusable tarp-style greenhouse cover.

Why it ranks #10: The 16 mil polyethylene tarp has light transmission and UV claims, but its tarp construction and grommets make it less suited to a fitted greenhouse film cover.

A woven, double-coated three-layer polyethylene construction sets this Ansgery cover apart from standard roll sheeting. This 16-mil clear tarp measures 14 by 20 feet, allows natural daylight through, and includes reinforced grommet details for securing it as a greenhouse cover.

The 16-mil thickness and woven, double-coated construction are specified to improve tear resistance and UV resistance, supporting use as a durable outdoor tarp. Its clear material lets natural daylight pass through, while the description says it helps distribute temperature evenly. Enlarged buttonholes are spaced about every 18 inches, with heavy-duty corner grommets, giving installers attachment points around the cover. The 14-by-20-foot tarp format and actual marked size make measurement important before choosing it for a greenhouse.

Skip it if you need a longer continuous film sheet for a large house; VEVOR's 25-by-40-foot greenhouse film offers that format.

Pick this Ansgery tarp for a greenhouse area that benefits from a thick, clear cover and grommet attachment points. Measure the structure carefully: its 14-by-20-foot tarp format has fixed dimensions, unlike a longer roll of film.
