Thickness Selection Guide
At 3 mil, these bags are classified as heavy duty. For reference: 1-1.5 mil suits lightweight items and dust protection, 2 mil handles general-purpose applications, while 3 mil provides the durability needed for sharp-edged parts, heavy small items, and industrial environments. When packaging hardware with threads, burrs, or pointed edges, 3 mil prevents the punctures and tears common with lighter-gauge bags.
