Applications
The 6 mil thickness makes these bags ideal for demanding applications where standard 2-4 mil bags fall short. Apparel and textile operations use these for protecting high-value sweaters, cashmere garments, and delicate knits during storage and fulfillment. Art galleries and print shops rely on this size for safeguarding 11x14 and 12x16 prints, photographs, and matted artwork. Industrial operations store components with sharp edges, metal parts, and machinery components that would puncture thinner materials. Archival storage applications benefit from the superior moisture barrier for long-term document and textile preservation.

Thickness Guide
Understanding mil thickness helps select the right bag for your application. At 6 mil, these are among the heaviest flat poly bags available - roughly the thickness of a heavy-duty tarp. For comparison: 1.5 mil suits light dust covers, 2 mil handles general storage, 4 mil manages industrial parts, and 6 mil provides maximum protection for the most demanding applications.
