Gauge to Microns Conversion

The measurement of laminated plastics and coex films can be a little unusual for people who have not worked with these materials before. A few notes, gauge is usually reserved for thicknesses below 1 mil. Microns measurements are usually rounded to the nearest whole integer. Mil to Micron conversion is usually the most important conversion to make when working with flexible barrier plastics. Mils being a US unit of measure and Micron (um or Micrometer) being a metric system measurement of thickness. Blow film thicknesses are controlled by the size of the “bubble” that forms when extruding the plastic. Laminated plastics usually are at a minimum 2 mil (50.8um), but can range anywhere from 2 mil to 5.5mil for most commercial applications. Some Mil-Spec materials can be as much as 10mil or 20 mil in thickness. Gauge to micron conversion is important to ensure that your film thickness is correct.
