The strength of a plastic bag is determined by its material and thickness. We already know that the material HDPE produces the strongest thick plastic bags, but what about thickness? Thicker bags are typically stronger than thinner bags of the same material. To determine the thickness of a plastic bag, or its gauge, you need to find its mil score.

Mil is a measurement used to express plastic bag thickness. A mil is equal to a thousandth of an inch. To get an idea of how bag thickness is expressed in mils, refer to these common examples of types of plastic bags:

Common grocery store bag: ½ mil
Bread bag: 1.5 mils
Clothing store shopping bag: 2 mils
Packaging for screws or nails: 4 mils
Extreme puncture resistance for industrial parts that are sharp or heavy: 6 mils
