Covalence Plastics 4ML CLR 10X50 10-by-50-Feet 4-Millimeter Tyco Polyethylene Plastic Sheeting, Clear, No Size, No Color

I used this to line a thermal storage tank in a greenhouse, it did work right up until i cut it with a razor. Not a fault of the product however i gave four stars due to the fact that once its cut it is almost impossible to tape/glue/weld this plastic back together, this may be my lack of knowledge but i tried duct tape (of course), packaging tape, rolling/folding and taping to no avail.It is a heavy duty plastic and I have used the leftovers as a tarp, drop cloth and many other things and it worked great.Update 4/2015So it turns out most plastics cannot be tapped together with any structural integrity, now that i am older and wiser i know that this stuff can be fused together very easily with parchment paper and a cloths iron.

Some reviewers complain that it's milky. It's actually quite clear, about what you'd expect from thick plastic. Not clear as glass, but certainly what I would call clear and what I would expect.

Fast deliver, product exactly as described, reasonable price... all is good.

Good product at a great price. Was delivered quickly.
