Gauge to mil
Divide the gauge number by 100. Example: 80 gauge = 0.80 mil.
BINGOPLAS TECHNICAL BUYER GUIDE
Stretch film gauge, mil and micron.
North American buyers often see stretch film thickness expressed in gauge or mil, while metric specifications use microns. The units can be converted—but equal nominal thickness does not guarantee equal film performance.
NOMINAL CONVERSION TABLE
Common gauge conversions.
The conversions below are mathematical equivalents. They do not represent BINGOPLAS product availability or a recommendation for a particular load.
| Decision point | Mil equivalent | Micron equivalent |
|---|---|---|
| 47 gauge | 0.47 mil | 11.94 microns |
| 60 gauge | 0.60 mil | 15.24 microns |
| 70 gauge | 0.70 mil | 17.78 microns |
| 80 gauge | 0.80 mil | 20.32 microns |
| 90 gauge | 0.90 mil | 22.86 microns |
| 100 gauge | 1.00 mil | 25.40 microns |
Formula: gauge ÷ 100 = mil; mil × 25.4 = microns. Supplier labels may use rounded metric equivalents, so the purchase specification should state the controlling unit.
THICKNESS IS ONLY ONE INPUT
Compare the application as well as the gauge.
Describe the load
Provide load weight, dimensions, stability, corners, puncture risks and the distribution or storage conditions the wrapped load must withstand.
Describe the wrap process
Identify manual or machine application, the equipment model, prestretch system if applicable, wrap pattern, overlap and normal settings.
Define the result
Evaluate load containment, punctures, film breaks, film used, rewraps and the condition of the load after normal handling.
FREQUENTLY ASKED QUESTIONS
Stretch film thickness questions.
Is 80 gauge stretch film the same as 20 micron film?
They are close nominal equivalents: 80 gauge equals 0.80 mil, which converts to 20.32 microns. Suppliers may round labels, so confirm the stated unit, nominal value and tolerance for the exact product.
Does a higher gauge always provide better load containment?
No. Thickness is only one variable. Resin formulation, layer structure, puncture behavior, stretch response, cling, wrap pattern, equipment settings and load profile also affect performance.
Can two films with the same nominal gauge perform differently?
Yes. Nominal thickness does not describe the complete film design. Compare the written specification and evaluate candidate films on the same loads under the same operating conditions.
