These 4 x 4 inch reclosable poly bags are built from 8 mil polyethylene, placing them in the super heavyweight category. The full-width track zipper spans the entire bag opening, delivering a secure, repeatable closure that holds through multiple open-and-close cycles without seal degradation.

The 8 mil construction provides substantially greater puncture and tear resistance than standard 2 or 4 mil alternatives, making these bags well suited for sharp-edged components, dense hardware, bulk samples, and retail display packaging. FDA and USDA compliance for direct food contact extends their use into food manufacturing, portioning, processing, and distribution environments.

All dimensions are interior measurements. Bags are sold in cases of 1,000 and are eligible to ship via parcel carrier.
