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 width. 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.
