Best greenhouse film in this eight-sheet comparison
Updated: October 2026
You need a clear cover for a small greenhouse or cold frame, and the star line seems to make the choice easy. It does not: the best greenhouse film in this set is not simply the listing with the highest rating, because reviews mix sizes and countries while several specifications contradict themselves. Our [greenhouse film comparison](/hub/raised-beds-greenhouses-and-compost/greenhouse-film) contains all eight rows. Within that set, AGGAFA B0D8HN9N8Z is our top pick and GSHUR B0D4723JDD is our best-value option, each with a clear limit that matters before you buy.

What best means in this set
These selections compare eight amazon.co.uk listings, not every greenhouse cover sold in Britain.
Specialist tunnel films set a higher bar: Northern publishes 180 micron with a five-season warranty, while First Tunnels lists 200 micron with a seven-year UV guarantee. Neither is one of these eight ASINs. The top pick means the best-supported choice among these eight rows. For gauges, read the greenhouse film buying guide.
Top pick: AGGAFA 150 µm, 2 m × 3 m
AGGAFA is the strongest-specified small sheet here. Its title and bullets state 150 µm, also written as 6 mil, and its 840 g listed weight is plausible for a 2 m × 3 m polyethylene sheet at that thickness. It costs £12.99, has a listing line of 4.5 from 110 reviews, and ranks number 10 in Greenhouse Covering Plastic. The bullets also state 90% light transmission, UV coating, five-layer extrusion and a life over four years. The four-year line is only a bullet, however, not a separate warranty field.
The selected size and installation bullet say 2 m × 3 m, but the model number contains 4M×5M. Buy AGGAFA for a small frame if you can measure it before cutting.
Best value: GSHUR 2 m × 2 m
GSHUR costs £7.99 and has the broadest UK review signal in the comparison. Its amazon.co.uk line is 4.5 from 650 reviews, and all first 50 reviews in the raw file are headed United Kingdom. Buyers describe using it on a small greenhouse, a cold frame and an allotment.
It is nevertheless less fully specified than AGGAFA. The listing gives no micron or mil thickness and no UV claim. One buyer used the sheet as a temporary outside roof and reported that it ripped in the first storm.
Buy GSHUR if you want the most-reviewed inexpensive sheet in this set for a cold frame, mini greenhouse or replaceable patch and will accept an unstated gauge. Skip it for a windy roof, a long-lived tunnel or any job requiring a published UV term.
Why higher stars or more area did not win
The smaller CHESTAF B0FCSMZ83Z shows 4.7 from 93, the highest star line among these sheets, and costs £8.99. One UK review says CHESTAF polythene was used to construct a large garden polytunnel. Yet the URL ASIN is B0FCSMZ83Z while the details ASIN is B0G44BFSNL, and the 2 m × 2 m title sits beside a dimensions line of 200 × 1 × 0.1 cm. The rating is therefore not clean evidence for this precise 2 m square, and no micron thickness is stated.
Pumtus B0FNBJYGGL is the largest plainly stated sheet at 3 m × 8 m, with a 6 mil line and an anti-drip bullet. Its £16.14 price can look compelling by area. However, only one of the seven raw-file reviews is headed United Kingdom, and that reviewer says the sheet was cut where it crossed cable ties. A US review reports breakdown within weeks.
Who should leave this set
Leave this set if you are covering a walking tunnel for several seasons. A proper cover must span the hoop, provide spare material at the ends and use a fitting system that controls tension. It should also give you a thickness and UV term you can read. The polytunnel cover guide explains why Pumtus’s 24 m² area still does not make it a warranted tunnel cover.
For a small frame, AGGAFA offers the best specification evidence and GSHUR offers the strongest cheap, UK-reviewed option. For a tunnel, neither should be stretched into a role it was not shown to fulfil.
Common questions
Why is AGGAFA the top pick rather than the 4.7-star CHESTAF?
AGGAFA states 150 µm and has a plausible corresponding weight, relevant UK small-greenhouse reviews and a Greenhouse Covering Plastic rank. CHESTAF’s 4.7-star pool includes other sizes, while its URL and details ASIN disagree and its dimensions line does not describe the 2 m square.
Why is GSHUR best value when it has no thickness?
At £7.99, GSHUR combines a low price with 4.5 from 650 and UK reviews describing a small greenhouse and cold frame. The missing gauge is a serious limitation, so the recommendation is for a replaceable small cover, not a multi-year tunnel skin.
Should I buy the 3 m × 8 m Pumtus sheet instead?
Choose it only if that area fits your frame and you accept a thin UK record. It states 6 mil and offers 24 m², but the raw file has one UK review, which reports cutting on cable ties, plus a US review reporting rapid breakdown.
Is there a sheet here with no reviews?
JEUIHAU B0FB2YGVGR has no customer-review line and no review text in the raw file. Its rating score is therefore empty rather than a judgement that the product deserves zero for quality.
Does “best” mean the best tunnel cover in Britain?
No. It means the strongest choice within these eight listings and this comparison method. Specialist UK tunnel covers publish measured specifications and warranties that these picks do not match.
