9 x 12" - (100 Pack) 4 Mil Reclosable Poly Bags

These 9 x 12 inch reclosable poly bags are built from 4 mil polyethylene, a gauge that delivers meaningfully greater puncture and tear resistance than standard 1–2 mil options. The 9 x 12 inch measurement reflects interior usable dimensions, giving buyers an accurate fit reference when matching bags to product size.

The full-width single-track zipper seal supports repeated open-and-close cycles without degrading closure performance, making these bags well-suited for retail display packaging, e-commerce fulfillment kitting, parts storage in manufacturing environments, and food-contact applications where resealability and contamination control are required. FDA and USDA compliance extends their use into regulated food and pharmaceutical packaging workflows.

Construction from 4 mil polyethylene provides added rigidity that handles heavier or irregular items without the flex or puncture risk common in lighter gauges. Each case contains 100 bags and ships via parcel carrier.
