Mil Thickness of Plastic Sheeting- What works best for what?

Common Uses For Different Thickness of Plastic Sheeting

Heavy Duty Plastic Sheeting:

Heavy Duty Plastic Sheeting- what is it? It first boils down to what job will the plastic sheeting be required to perform? A six mil reinforced film can be considered "heavy-duty" when it is used to cover a desk to keep it clear of dust. That same "heavy-duty sheet" would not be strong enough to line a landfill.

 Understanding the strength and thickness of the film, it's composition and additives and chemical make-up, as well as the job it has to perform, will help determine if a film is fit for the job at hand. It is critical that the film not only is assessed on its mil thickness.  For example, if the film is in the sun, it needs UV protection additives to maintain its strength.

Don't confuse a micron with a mil.

How thick is a micron?

A micron is a unit of measure in the metric system equal to 1 millionth of a meter in length (about 39 millionths of an inch). The average cross-section of a human hair is 50 microns.

How thick is a mil?

A mil is a measurement that equals one-thousandth of an inch, or 0.001 inch. Most human hair is One-thousandth of inch, or 0.001 inch. The most common size in the thickness rating for plastic sheeting is 6 mil. This is 6-thousandths of an inch, or 0.006 inch.
