Applications
The 3 mil thickness makes these bags the right choice when standard 2 mil won't cut it. Hardware distributors use them for screws, nuts, bolts, washers, and small fasteners that could puncture lighter bags. Jewelry manufacturers rely on this size for storing and shipping earring backs, jump rings, clasps, and small findings. Coin dealers and collectors choose 3 mil protection for numismatic storage. Electronics assemblers package small components, connectors, and pins. The compact 3x3 size fits perfectly in parts bins, drawer organizers, and inventory systems.

Thickness Guide
Choosing the right mil thickness matters. At 3 mil, these bags are classified as heavy duty—50% thicker than standard 2 mil bags. This extra material provides meaningful puncture resistance for metal parts, better moisture barrier properties, and increased durability for items that will be handled repeatedly. For lightweight items without sharp edges, 2 mil may suffice. For extreme applications, consider 4 mil or 6 mil options.
