Commercial Applications
The 3 mil thickness makes these bags a preferred choice across multiple industries. Hardware distributors use them for screws, nuts, bolts, and small fastener kits where bag integrity matters. Electronics manufacturers rely on the puncture resistance for protecting small components during storage and shipping. Jewelry suppliers choose this gauge for heavier findings, clasps, and metal components. Machine shops package small precision parts, o-rings, and gaskets without concern for sharp edges puncturing the bag.

Thickness Guide
Bag mil thickness determines durability and application suitability. Light-duty 1.5 mil bags work for dust covers and lightweight items. Standard 2 mil handles most general packaging needs. These 3 mil bags serve heavy-duty requirements where puncture resistance is critical. For extreme applications with very sharp or abrasive contents, consider 4 mil or 6 mil options.
