These 3 x 3 inch reclosable poly bags are built from 4 mil polyethylene, a heavier gauge than standard 2 mil options, delivering meaningful puncture resistance and a reliable moisture barrier. The single-track zip closure spans the full bag width, allowing repeated opening and resealing without degrading seal integrity.

The 4 mil construction makes these bags well suited for small hardware, electronic components, pharmaceutical samples, jewelry, and retail consumer goods where a secure, resealable enclosure is required. FDA and USDA compliance supports use in food-contact and regulated-product applications across food processing, laboratory, and direct-to-consumer environments.

Stated dimensions reflect interior usable capacity. Each case contains 1,000 bags and is eligible to ship via parcel carrier.
