The average thickness of the film is 6 mils thick. A 6-mil polyethylene film is about the thickness of a sheet of paper. The thickness is important because it determines the amount of light that can pass through the film. The thicker the coating, the more light it can block out.
For example, if you have a greenhouse with a coating of 1 mil, and you put a light bulb in the greenhouse, it will block the light from the bulb, but it won’t block all of it. If you want to cover the entire greenhouse with the same film, you’ll need to use a thicker coating.
