You want a sheet that still holds after a season of sun and wind, not one that tears in the first storm. For most people, the A&A 8 mil greenhouse film at 20 ft. wide is the one to buy. It is a true 8 mil (8 thousandths of an inch thick) roll, so it stands up to weather instead of splitting. Below are three rolls that are genuinely 8 mil, ranked by what each one does well. That way you match a roll to your job instead of guessing at a thickness label.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
An 8 mil sheet is roughly.008 inches of polyethylene, and the difference between a good roll and a frustrating one usually shows up in UV life, true width, and whether the film stays see-through. This breakdown of 8 mil plastic sheeting covers the three rolls worth your time and the exact jobs each one suits.
Our Picks at a Glance
How To Choose The Best 8 Mil Plastic Sheeting
The first thing to get straight is that every roll here is the same thickness. At.008 inches, an 8 mil sheet is the heavy-duty step up from the 6 mil film most hardware stores stock. Once thickness is equal, the buying decision moves to three things: how long the UV protection lasts, how wide and long the roll is, and whether the film is actually clear enough for your job.
Match the UV rating to how long the cover stays up
UV additives are the chemicals blended into the polyethylene to slow sun damage. They are the single biggest reason one 8 mil greenhouse film outlasts another on the same frame. A film rated for 5 years of UV resistance is built for a permanent hoop house you plan to leave standing. A 4 year rating still covers multiple growing seasons, and for a seasonal cold frame or a one-off project it is more than enough. If you are buying general-purpose sheeting for a crawl space or a paint booth, UV life matters far less than width and toughness.
Check the true width before you order
Width is where rolls differ most. A 10 ft. roll covers a narrow bed or a standard crawl space run. A 20 ft. roll wraps a wide hoop house in fewer passes, which means fewer seams and fewer places for wind to grab. Measure the span you are covering, then add slack for the overhang you will bury or staple. Ordering too narrow is the most common mistake — you end up seaming two sheets together right where the weather hits hardest.
Decide if you need see-through film
Greenhouse film is meant to pass light so plants underneath get even exposure and even temperatures. General-purpose polyethylene sheeting is built for blocking and protecting, not for letting light through. If your job is growing, buy the greenhouse film. If your job is sealing, masking, or covering equipment, a general sheet does the job and the haze does not matter.

In‑Depth Reviews
1. A&A Clear Greenhouse Plastic Sheeting 8 Mil (20 ft. W x 25 ft. L)
Our pick — 4.5+★ from 100+ verified ratings; the strongest balance of quality and price.
The widest roll here by a long way, built to wrap a hoop house in fewer passes.
Twenty feet of width is the headline. That is twice the span of the 10 ft. Farm Plastic Supply vapor barrier roll, so a wide structure gets covered with one sheet instead of a seamed pair. Fewer seams means fewer weak points where wind works its way under the film.
The UV side is the strongest in this lineup too. A&A builds this film with anti-aging UV additives rated for 5 years of sun resistance, versus the 4 year rating on the 16′ x 25′ Farm Plastic Supply film. If you are leaving a hoop house standing through multiple seasons, that extra year of protection is the reason to pick this roll.
Buyers consistently say it meets expectations and expect it to stay on the frame for years. Light passes through evenly rather than in hot spots. One caution before you order: the roll is sized 20 ft. wide by 25 ft. long, so measure your span first. A 25 ft. length will not wrap a long tunnel in one piece.
Where this roll earns its place
- 20 ft. width — double the 10 ft. span of the Farm Plastic Supply roll, so fewer seams
- 5 year UV resistance, the longest rating in this lineup
- Even light transmission for consistent crop growth and temperature
- Doubles as a vapor barrier or construction dust wall
What to weigh before buying
- 25 ft. length limits it to shorter structures or a partial wrap
- Sold as a single roll, so plan your cut layout first
Made for: hoop houses and greenhouses wide enough that a 10 ft. roll would force a seam down the middle.
Measure first: if your run is longer than 25 ft., you will be joining two lengths regardless of width.
2. Farm Plastic Supply Clear Greenhouse Plastic Sheeting 8 mil (16′ x 25′)
Sixteen pounds of film that shrugs off weather a lighter sheet would not survive.
Here is a number that tells you a lot: this roll weighs 16 pounds. The 10′ x 100′ Farm Plastic Supply roll weighs 50 pounds. Same thickness, far less material — because this one is a 16′ x 25′ cut, not a 100 ft. run. For a small greenhouse, a pergola garden, or a single cold frame, that is exactly the amount you want to handle alone on a ladder.
Durability is the most-praised trait in reviews of this 16′ x 25′ film. Buyers report it surviving a small tornado while still on the frame, and using it as a pool cover as well as a greenhouse cover. The 4 year UV rating is one year behind the A&A roll, but on a smaller structure that difference is easy to live with.
The one honest hitch is thickness. Some buyers describe the film as feeling thinner in hand than they expected for an 8 mil sheet. It is still sold and specified as true 8 mil polyethylene, and the durability record speaks for itself, but do not expect a stiff, board-like sheet. Treat it as film, install it taut, and it performs.
Handling advantage: at 16 pounds this is a roll one person can carry, unroll, and reposition without help — a real plus when you are working overhead on a small frame.
Verify your span: 16 ft. wide covers most backyard greenhouses, but it is narrower than the A&A roll, so a wide structure will need a seam.
Reach for this if you are covering a compact greenhouse, a pergola, or a pool and want a roll you can manage solo.
Look elsewhere if you need maximum UV life on a permanent structure or a span wider than 16 ft.
3. Farm Plastic Supply Clear Plastic Sheeting 8 mil (10′ x 100′)
A hundred feet of heavy LDPE for sealing, masking, and covering — not for growing.
Sheer length is the point of this roll: 100 ft. of 10 ft. wide film, four times the run of the A&A greenhouse roll, and it weighs 50 pounds for it. That is a crawl space vapor barrier, a full-room dust wall, or enough drop cloth to cover machinery and lumber in one go. Low-density polyethylene, or LDPE, is the flexible, tear-resistant plastic that makes it work as a painter’s tarp without cracking when you drape it.
Reviewers praise this 10′ x 100′ LDPE sheet for toughness and tear resistance in real use. It stands up to rain, wind, cold, and heat, and it does not rip easily when dragged across a floor or stapled to a rim joist. Builders, hobbyists, and DIYers use it as a default sheet for general protection work.
Now the catch, and it is a real one for some buyers: this sheet is not see-through the way greenhouse film is. It reads as opaque white rather than clear, which is a nuisance if you wanted light to pass through. For blocking, sealing, and containing, the haze is irrelevant. Opinions on value split: many call the 100 ft. roll the best value around, while others say it is more film than their job needed. Match it to a big job and it makes sense.
Why it suits big containment work
- 100 ft. length covers long runs without a splice
- LDPE film resists tearing when dragged or stapled
- Handles rain, wind, cold, and heat outdoors
- Works as vapor barrier, dust wall, spray barrier, or equipment cover
The trade-offs to expect
- Reads opaque white rather than clear — not a light-transmitting greenhouse film
- 50 pounds of roll means two hands and some space to unroll it
Best used for: crawl spaces, paint and dust containment, and covering lumber or machinery where blocking beats clarity.
Not the one for: a greenhouse cover, since the film does not pass light the way a dedicated greenhouse sheet does.
Understanding the Specs
Mil Thickness
Mil is a measurement of film thickness, and 8 mil equals.008 inches. It is the heavy-duty middle ground above the 6 mil film most stores stock — thick enough to resist tearing and wind, still flexible enough to drape and staple. All three rolls here are true 8 mil, so thickness is not how you separate them.
UV Resistance
UV additives are blended into the polyethylene to slow sun damage, and the rating tells you how many years of exposure the film is built for. A greenhouse cover that stays up year-round needs the longest rating you can get. A seasonal cover or an indoor job needs far less. Ratings here run 4 years to 5 years.
Polyethylene Type
Low-density polyethylene, or LDPE, is the flexible, tough plastic used in these rolls. It resists cracking when folded or dragged, which is why it works as a painter’s tarp and a vapor barrier. Greenhouse films use the same base plastic with UV additives and a formulation tuned for light transmission.
Roll Size and Coverage
Width and length decide how many seams you create. A wider roll wraps a structure in fewer passes. A longer roll covers a crawl space or a masking job without splicing. Match both dimensions to the job, then add overhang for stapling or burying the edge.

Final Thoughts: The Verdict
For most people, the winner in this lineup is the A&A Clear Greenhouse Plastic Sheeting 8 Mil because 20 ft. of width and a 5 year UV rating cover a real hoop house with the fewest seams and the longest protection. If you are covering something smaller and want a roll you can handle alone, grab the Farm Plastic Supply 16′ x 25′ film. And for crawl spaces, dust walls, and covering equipment, the Farm Plastic Supply 10′ x 100′ roll is the one to reach for. Whichever you pick, buy for the job in front of you — a wide, long-rated roll on a small frame is money spent on coverage you will never unroll.
