Definitions of commonly used thickness terms
Gauge: refers to the thickness of the film
Mils: standard term used to measure the thickness of film
in thousands of an inch.
In reference to thickness or gauge, is “mils” the same as millimeters or microns?
No. The gauge or thickness of plastic film is expressed in thousands of an inch, said as “mils”. For example, .005" is said “5 mils”.
These are all different forms of measurement. One millimeter
= .039" or “39 mils” thick.
About how thick is a mil?
A piece of copier paper is about .004" (4 mils) thick.
Typically, what thickness of film does Grafix stock?
Each item is different and should be checked. However, Grafix
usually does not stock film thinner than .001" (1 mil) and
thicker than .020" (20 mil).
