Manufacturing facilities use these bags to protect finished assemblies, machinery components, and large fabricated parts during storage and transit. Warehouse operations rely on the heavy 4 mil construction for covering equipment, protecting inventory from dust and moisture, and packaging bulky items. The size works well for automotive parts, HVAC components, small appliances, electronics, rolled textiles, and oversized documents or artwork. E-commerce fulfillment centers stock this dimension for large merchandise that exceeds standard poly bag capacities.

Mil Thickness Guide
The 4 mil thickness on these bags represents heavy-duty construction suitable for industrial applications. For reference: 2 mil handles general-purpose lightweight packaging, 3 mil provides medium-duty protection, and 4 mil delivers the puncture resistance needed for sharp-edged parts, heavy components, and demanding warehouse environments. Choose 4 mil when contents have rough surfaces, sharp corners, or significant weight.
