Plastic Sheeting Rolls/ Plastic Sheets -Thickness In Mils- Shop by Thickness

Plastic sheeting comes in various thicknesses, which are measured in "mil." A mil is equal to one-thousandth of an inch or 0.001 inch, similar to the thickness of a human hair. The most common thickness rating for plastic sheeting is 6 mil, which is 0.006 inch or 6-thousandths of an inch. Generally, thicker plastic is stronger, and if it has string or scrim reinforcement, it gains additional strength from the embedded string.

However, the composition of the plastic can also be crucial, regardless of thickness. For example, if fire retardant properties are required, additives in the plastic, such as fire retardant additives, play a more significant role than the thickness itself.

It's important to note that the term "heavy gauge" should not be confused with "heavy mil" when referring to plastic sheeting. "Gauge" is used to measure the thickness of metal and does not apply to plastic sheets.

To understand the differences between mil, mm, and inches, you can find more information here. Similarly, you can learn about the distinctions between micron and mil.

If you have a project and need guidance, we have some questions that can help. You can find them here.

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, its 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 be assessed on its mil thickness.  For example, if the film is in the sun, it needs UV protection additives to maintain its strength.
