Understanding Gauge Thickness
Gauge is a term used to describe thickness. Film thickness is no longer the standard for judging bag strength. Advanced resins and additives have allowed manufacturers to produce thinner, lighter can liners that are stronger than thicker bags made from lesser quality materials. Linear Low-Density Can Liners (LLD) are measured by mil thickness; High-Density Can Liners (HD) are measured by Micron thickness.
Mil (one thousandth of an inch) - One mil equals .001". Can liners range between .35 to 4.0 mils
Micron - 25.4 microns equals .001". 1,000 microns (M) is 1mm. Can liners range between 5 to 24 microns

Gauge Equivalents
Static load (lifting strength) is the best way to choose bag strength. Below are the approximate gauge equivalents for static load:
