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

Plastic Sheeting comes in a wide range of thicknesses.  It is rated with the term, "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. Generally, the thicker the plastic, the stronger it is.  If it has string/scrim reinforcement, then the string within the plastic will give it added strength. Depending on the application, the composition of the plastic can play a big role regardless of the thickness.  For example, additives added to the plastic such as the fire retardant additive may play a more significant role than the thickness of the plastic if the job requires FR/ flame retardant plastic.

Note that the term " heavy gauge" plastic is not to be confused with "heavy mil" referring to heavy plastic sheeting. The term "gauge" refers to the thickness of metal. It really doesn't apply to plastic sheeting/ plastic sheets.
