Thickness Selection Guide
At 4 mil, these bags fall into the heavy-duty category. For reference: 1-1.5 mil suits dust covers and light products, 2 mil handles general purpose needs, 3-4 mil provides industrial-grade protection for heavy or sharp items, and 6 mil serves extreme applications. Choose 4 mil when packaging metal parts, tools, automotive components, or anything with edges that could puncture thinner material.
