These 3 x 5 inch reclosable poly bags are built from 4 mil polyethylene, a heavy-duty thickness that delivers meaningfully greater puncture and tear resistance than standard 2 mil options. The full-width single-track zipper closure creates a secure, moisture-resistant seal that holds reliably through repeated open-and-reseal cycles.

The 4 mil construction makes these bags well suited for items with sharp edges, irregular surfaces, or abrasive textures. Common applications include hardware kits, electronic components, pharmaceutical samples, retail hang-sell items, and food-contact packaging — the bags meet FDA and USDA requirements for regulated-environment use.

Dimensions reflect the interior usable area. Each case contains 1,000 bags and is eligible to ship via parcel carrier.
