These 3 x 5 inch reclosable poly bags are built from 8 mil polyethylene, placing them in the super heavyweight category for demanding packaging applications. The full-width track zipper spans the entire bag opening, delivering a secure, repeatable seal that holds through repeated handling and reuse.

The 8 mil construction resists puncture and tearing from sharp-edged components, dense hardware, and irregularly shaped parts — materials that compromise thinner poly bags. FDA and USDA compliance also makes these bags appropriate for food-contact use, extending their utility to food manufacturing, specialty retail, and lab or medical supply environments alongside industrial and distribution settings.

All listed dimensions reflect interior measurements. Each case contains 1,000 bags and is eligible to ship via parcel carrier, making routine replenishment practical for high-volume packaging lines. Buying by the case reduces per-unit cost for warehouses, manufacturers, and fulfillment operations.
