Thickness
The thickness, or "gauge", of a plastic bag refers to the thickness of a single wall of the bag, generally measured in mils, or thousandths of an inch (1000 mil = 1 inch).
(Note: Bags are sometimes measured in microns (mic). To convert between mils and microns: 25.4 microns = 1 mil.)
Typical Thicknesses for Low Density Bags
Light weight bags: 0.8 - 1.25 mil
Typical uses: Produce bags. Ideal for economical coverage of lightweight products.
Standard weight bags: 1.5 mil
Typical uses: food, scratch protection, storing, display.
Medium weight commercial bags: 2.0 mil
Typical uses: foods, garments, shipping.
Heavy weight bags: 3 - 5 mil
Typical uses: parts, for shipping scuff and tear resistance
Extra-heavy weight bags: 6 - 8 mil
Typical uses: tools, metal products, total protection of heaviest products |
