Thickness Guide
At 3 mil, these bags fall in the heavy-duty category—significantly thicker than standard 1.5-2 mil bags. Choose 3 mil when packaging items with sharp corners, metal parts, or anything requiring extra puncture protection. For lighter-duty applications, consider our 2 mil options; for extreme protection, see our 4 mil and 6 mil bags.
