“Gauge” measures a film’s thickness and depends on film type: the higher the gauge; the thicker the film. The tool used to measure film gauge is referred to as a micrometer.
Selecting the proper gauge for your packaging can be a complex process with many consideration factors, including, but not limited to: intended use, strength, overall appearance, environmental impact, cost and much more.
Flexible film is measured in either mil (0.001 inches) or microns (0.001 millimeters).
For Example:
3 mil = 0.003 inches
30 microns = 0.030 millimeters
