These 18 x 20 inch reclosable poly bags are built from 4 mil polyethylene with a single-track zipper closure that spans the full bag width. The heavier gauge construction delivers meaningfully greater puncture and tear resistance than standard 2 mil bags, making them a reliable choice when contents are dense, sharp-edged, or irregularly shaped.

FDA and USDA compliance makes these bags suitable for food-contact, pharmaceutical, and regulated distribution environments. They perform equally well in general warehousing, parts storage, kitting operations, and retail packaging where a resealable closure reduces waste and supports repeated open-and-close cycles during inspection or fulfillment.

Bags are made from clear polyethylene, and all stated dimensions reflect the interior usable area. Each case contains 500 bags and is eligible to ship via parcel carrier.
