These 4 x 4 inch reclosable poly bags are built from 4 mil polyethylene, a thickness that provides meaningfully greater puncture and tear resistance than standard 2 mil alternatives. The single-track zipper closure spans the full width of the bag opening, delivering a consistent resealable seal through repeated open-and-close cycles.

The 4 mil construction and FDA/USDA compliance make these bags practical across food packaging, pharmaceuticals, hardware and small parts kitting, retail display, and laboratory sample storage. Their square footprint suits compact items that shift or tangle inside larger bags.

Each case contains 200 bags and is eligible to ship via parcel carrier, making it easy to stock pack stations, retail counters, or fulfillment lines without committing to large-format orders.
