These 13 x 18 inch reclosable poly bags are built from 4 mil polyethylene with a full-width single-track zipper seal that runs the entire width of the opening. The heavier 4 mil construction delivers meaningfully greater puncture resistance than standard 2 mil alternatives, making it the right choice when contents are heavy, irregularly shaped, or require a more durable barrier.

The reclosable zipper supports repeated open-and-reseal cycles without loss of closure integrity, making these bags practical for kitting operations, parts storage, sample packaging, food portioning, and retail or e-commerce fulfillment. FDA and USDA compliance broadens their applicability to food-contact environments and other regulated industries where material safety documentation matters.

Dimensions reflect interior usable space. Bags are manufactured from clear polyethylene, allowing contents to be identified without opening. Each case contains 500 bags and is eligible to ship via parcel carrier.
