While this can certainly be used as a vapor barrier as per the description, it is also used very extensively as a light barrier and reflective surface for indoor gardening. The 10 mil thickness makes it durable enough to place on the floor or the walls. The black side prevents light from penetrating through while the white side reflects it.

Our whole family just spent an afternoon picking out seeds for different herbs and vegetables for our garden and planting them in plugs in a seedling tray. I lined the inside of a large box with this film (white side visible), placed a warming mat inside the box, added the seedling tray and then placed a grow light above it. Fingers crossed, in a few months we should be eating some nice home grown food from our garden.

5 out of 5 stars - Thick, durable, and versatile material. Highly recommended.

We bake our soft pretzels the old world way, dipping them in Lye Bath (sodium hydroxide) prior to baking. Given this, we need to lay down a protective layer on the floor to catch any drips or splashes. Had been using a thinner plastic sheeting but it would get beat up fairly quickly and have to be replaced. Now with using the Purteria 6 mil White Heavy Duty Plastic Sheeting, we have a layer of strong and durable protection that holds up under the traffic we put to it. We are also using it to provide greater protection to our dough moulder. The plastic sheeting helps keep dust and dirt out. Excellent quality.

This Purteria 10 mil Vapor Barrier, 10'x65', White Plastic Sheeting Heavy Duty for Crawl Space Encapsulation, Crawl Space Vapor Barrier, Plastic Drop Cloth Vapor Barrier for Crawlspace, Polyethylene Film may seem a bit expensive, but not really. Not when you consider how thick it is and how much is in this roll.

This is a heavy duty, quality plastic sheeting that can be used for many different things and it can be cut to size. Just to give you an idea of how thick it is, when I went to pick up the package, I was floored at how heavy it was - could barely carry it into the house! This isn't your average thin sheeting; this is awesome!

I used this sheeting for wrapping mattresses. It's a good thickness for the job. It comes tightly rolled and protected in the box by an outer covering. It's a little pricey, but it is 6mil delivered to your door, so it does offer a particular value that I appreciate. This roll of plastic sheeting is as described as far as I can tell and has been a satisfying purchase.

The material is very robust and is white on both sides. It takes a little while for the folds to flatten out, but otherwise, spreads nicely. Given the tight spaces in most crawlspaces, you’ll want to measure the length(s) you need first, and then cut the pieces to approximate size in a large open area. Then bring the pre-cut sections into the crawlspace for installation.
