Industrial Applications
The 4 mil thickness makes these bags ideal for operations handling parts and equipment that would puncture lighter-weight poly. Automotive shops use them for engine components, brake parts, and hardware kits with sharp edges. Manufacturing facilities rely on this gauge for machined parts, castings, and assemblies that need protection during storage and transit. Maintenance departments stock them for spare parts inventory and equipment covers.
The 12x18 size accommodates larger components including small engine parts, electronic assemblies, pump components, and multi-part hardware kits. Clear LDPE material allows visual identification without opening bags, reducing handling time in warehouse and shop floor operations.

Thickness Guide
4 mil bags are classified as heavy-duty industrial grade. For reference: 1.5 mil handles lightweight items, 2 mil covers general purpose applications, and 4 mil provides the puncture resistance needed for metal parts, tools, and equipment with edges or points. Choose 4 mil whenever standard poly bags have failed or when parts have sharp characteristics.
