Black & White Poly Film 5.5 Mil 10' x 100'

The product was excellent and true to form and worked as needed.

Not sure why some people report getting a size different than listed - must be another seller hijacking the item... Mine came in a large roll, definitely 10ft wide by presumably 100ft long. For my purposes, I'm using it to block light from coming into a room, and I'm tacking it up to wooden indoor shutters. The white-outside black-inside combination works perfectly - from the outside, if you go up and look in the window you can see the white sheet, but from the inside the black is basically invisible on the opposite side of the shutters. I ordered the 5.5 thickness, and no visible light looks to be making it through, the only leakage I have is on the sides of the shutters but not enough to make me want to change anything.The thickness seems consistent, and my only real complaint would be the creases in the material, but short of putting it on a 10ft roll (which would be impractical to ship), I don't know how you would solve it. Cutting is trivial, you can pretty much use anything with a sharp edge. Under the Arizona heat in the summer hasn't seemed to affect the plastic in any meaningful way - no drooping or sagging that I can tell.All in all a great buy, especially considering the overall length.

This film is fantastic. The rolls are definitely easier for me than the smaller folded sheets. It's pretty thick and is absolutely light-proof. I've wrapped several bulbs with spare pieces to see if any light would leak out and the room goes black when covered. Not even a hint that a bright light is behind it. I applied mine with staple's and haven't had any tears or rips yet. Would definitely buy again.

Works great! My room is 9'x12' so I didn't have to cut anything. I just rolled out the polysheeting & kept going.... wrapped my entire greenhouse top to bottom with just 3 pieces. I have a bunch left over that I'm going to use for potato pots & hanging strawberry sacks. All made out of the same material why not use it up & save some $$$.

I've used this for years, buying 20 or 30 feet at a time from local retailers, and paying well over double the price I paid here. Excellent strength, and complete light blocking with excellent reflective quality on the white side. I use this in my indoor grow room, as well as outdoors to protect photo sensitive plants from light during their flowering cycle, as well as frost or bad weather protection for those of us with a short high altitude growing season. I've had some outdoors for several years at well over a mile high with bone chilling winters and 100+ degree summers. Good Stuff, Maynard!

I love this stuff. It’s thick and tough. I doubled sided it so the white is on the outside and put it in a window. It works great as a blackout and keeps out the heat. Works in planters too!

Used this on the walls inside my garage to help seal up drafts and brighten up the interior. Worked great. Product is as described. Going to install it on the ceiling to reflect light down and keep heat down in my work area.

Using for indoor grow rooms. The black blocks out ambient light and keeps in grow light. While the white side faces plants and insures the plants absorb most of the life giving light.
