These 3 x 12 inch reclosable poly bags are built from 4 mil polyethylene with a full-width single-track zipper that delivers a secure, resealable closure protecting contents from moisture, dust, and contamination. The 4 mil construction provides meaningfully greater puncture resistance and rigidity than standard 2 mil bags, making them well suited for heavier, sharper, or irregularly shaped items.

The narrow, elongated format serves applications where standard square bags waste space or fit poorly — including hardware components, craft supplies, medical instruments, test strips, stir sticks, and promotional inserts. The reclosable zipper makes these practical for retail display, kitting operations, and any workflow where bags are opened and resealed repeatedly across pack cycles.

All listed dimensions reflect interior usable space. These bags meet FDA and USDA requirements, qualifying them for direct food-contact use alongside general industrial and distribution applications. Each case contains 1,000 bags and is eligible to ship via parcel carrier.
